==London Grinds==
Can be done without leaving London.
===Publishing Newspapers===
'''Requirements'''
*{{IL|Shadowy}} 217
*{{IL|Newspaper}}
*{{IL|Watchful}} 200 or {{IL|Persuasive}} 200
'''Expected EPA: 3.73 (3.93 with extra requirements, 4.21 when combined with Rat market)'''
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
'''Extra recommendations'''
*{{IL|Renown: The Great Game}} 40
*{{IL|Teaching Reputation of Your Laboratory}} 20
*(Active) enough acquaintances that they hire assassins equally fast or faster than you [[A column revealing certain facts about an acquaintance|slight them]]

*See [[Publishing a Newspaper (Guide)|Publishing a Newspaper]] for more information.

'''Basic cycle'''
#Finish the [[The Missing Woman|'The missing Woman']] carousel in {{IL|Wilmot's End}} to get {{IL|Whirring Contraption|2 x}}s.
#Use them in {{IL|Doubt Street}} to publish any edition requiring 104 pages of copy (note that this requires '''not''' taking '[[Employ a little theatrical accountancy]]' option).
A full cycle is items worth 138 {{e}} for 37 actions, a total of '''3.73 EPA.'''

'''With recommended'''
#<li value="2">Take only and all Salacious options including [[A column revealing certain facts about an acquaintance]].
#Publish [[A gossipy and tantalising edition]].</li>
This will result in {{IL|Journal of Infamy|148 x}} and {{IL|Sulky Bat|2 x}}s (by [[The interception of scandal]]). While [[A column revealing certain facts about an acquaintance|slighting]] consumes {{IL|Scrap of Incendiary Gossip|Appearance=Scraps of Incendiary Gossip|2 x}}, that is equivalent to 0.35 actions since you can [[Publish a seditious edition]] twice (also using slight) and earn {{IL|Scrap of Incendiary Gossip|214 x}} in 37 actions.
A full cycle is items worth 148.8 {{e}} for 37.35 actions, a total of '''3.98 EPA.'''

If whomever you've '''Slighted''' [[Respond to a social slight|retaliates]], then this gives you a 12.5 {{e}} item for an extra action on that card. So this means 173.8 {{e}} over 39.35 actions = '''4.416 EPA'''.

===Mr Chimes' Grand Clearing-Out Unveiled activities===
*Expected EPA: Up to '''3.8 EPA''' with {{IL|Watchful}} 297
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
[[Mr Chimes' Grand Clearing-Out (historical)|Mr Chimes' Grand Clearing-Out]] added five new activities similar to Brawling with Dockers. There are many differences from Brawling, but the most relevant to Money-Making are the lack of difficulty scaling and lack of caps on secondary rewards. This means that you can spend as long as you want raising progress quality simply by repeating the single most efficient option, allowing us to amortize actions spent on entering/claiming the rewards/exiting. Since one point of every progress quality is worth 0.1 {{e}}, EPA is essentially progress per action/10. Below are listed ''maximum'' EPAs for each activity.
*[[Seeking Documents in the Sunken Embassy|The Sunken Embassy]] - '''3.8 EPA''' with [[Seek out spy-holes]] (requires {{IL|Watchful}} 297 to 100%).
*[[Assist an Unfinished Man|Underclay]] - '''3.3 EPA''' with [[Commingle fact and falsehood]] (requires {{IL|Mithridacy}} 15 to 100%) or [[Convince the Calcified Man that you are of Polythreme]] (requires {{IL|A Clay Arm}} to access and {{IL|Mithridacy}} 10 to 100%).
*[[Sides in a Debate|Spider Symposium]] - '''3.2 EPA''' with [[Posit that language makes reality]] (requires {{IL|Persuasive}} 300 to 100%).
*[["Welcome to L.B. Industries!"|L.B. Industries]] - '''3.2 EPA''' with [[Assist with assembly]] (requires {{IL|Shadowy}} 297 to 100%).
*[[Hunt Bees in Old Newgate|Old Newgate]] - '''2.85 EPA''' with cycling between best randomizer options, [[Betray both sides]]/[[Hunt a swarm of drones]]/[[Commune with the bees]] (requires {{IL|Dangerous}} 209, {{IL|Monstrous Anatomy}} 7 and {{IL|Mithridacy}} 10 to 100% all three).
For a detailed breakdown of options and rewards in these activities see respective guides - [[The Sunken Embassy (Guide)]], [[Underclay (Guide)]], [[The Spider Symposium (Guide)]], [[L. B. Industries (Guide)]], [[Hunting Bees in Old Newgate (Guide)]].

===The Tomb of the Silken Thread===
'''Requirements:'''
*{{IL|Watchful}} 267
'''Expected EPA: 3.41'''
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
*See [[Forgotten Quarter Expeditions (Guide)]].

*Buying {{IL|Strong-Backed Labour}} to [[Burly guards and porters|fund]] expeditions to [[The Tomb of the Silken Thread 1|The Tomb of the Silken Thread]] gives [https://www.reddit.com/r/fallenlondon/comments/9ptuju/profitable_ways_of_spending_basic_resources_in/e87s1ts '''2.9096 EPA'''] (if you reinvest the profits into more SBL).
*Obtaining {{IL|Strong-Backed Labour}} from [[Send an Unfinished Man to Spite|The Underclay]] approaches '''3.409 EPA'''.
*Using Docks Favours exclusively to fund expeditions (and acquiring Rostygold at 3EPA by [[Intervene in a Dockers' Brawl|Brawling]]) gives '''4.272 EPA'''.
</div>

===Brawling with Dockers===
*Requires high {{IL|Dangerous}}
*Expected EPA: '''2.1-3.3'''
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
If you have unlocked [[Intervene in a Dockers' Brawl]], you can use it to grind echoes with varying efficiency depending on whether you're fighting in group or solo, specific crates you pick and your {{IL|Dangerous}}, Skills, BDR and items. For a detailed breakdown of options and rewards see [[Brawling with Dockers (Guide)]] - this grind focuses purely on earning eсhoes. Most relevant crates for that are:
*[[Accept a share of the extremely dusty crates]]/[[Claim the extremely dusty crates]] - 100/150 Brawling for 27.5/40 {{e}} (27.94/40.64 with access to {{IL|Upper River}}).
*[[Accept a share of the coffer of Admiralty maps]]/[[Claim the coffer of Admiralty maps]] - 90/140 Brawling for 25/37.5 {{e}} and 0.25 {{e}} per each point of Brawling above the requirement (up to 100/150).
*[[Accept a share of the crates cleared out of Saint Cyriac's Illuminated College]]/[[Claim the crates cleared out of Saint Cyriac's Illuminated College]] - 50/70 Brawling for 15/20 {{e}} and 0.25 {{e}} per each point of Brawling above the requirement (up to 100/150).
While there's a large number of possible combinations of options, this guide focuses on establishing overall EPA ranges, and so only analyzes least-demanding and most-demanding strategies. Regarding the most demanding - with rare successes estimated at 25%, average Brawling per action gain is 14.25 (in group)/15.5 (solo) for BDR/Skill options, 14.25/16.25 for Airs options, and 11.625/14.125 for [[Fight without taking your eye off the goods!]] combined with Airs options (available 50% of the time on average). However, since Airs options are only possible to 100% after reducing their difficulty with accumulated Brawling, you can't use them from the start.
*Least-demanding - have Dangerous 209/292 and simply repeat [[Fight without taking your eye off the goods!]] until getting to target Brawling amount, for 9/12 Brawling per action.
*Most-demanding - have Dangerous 274/304 and at least one out of:
**{{IL|A Hunter's Instinct for Nightmares}} and an outfit with {{IL|Dreaded}} 15 and {{IL|Monstrous Anatomy}} 13.
**{{IL|Honed Ushanka}} and an outfit with {{IL|Bizarre}} 15 and {{IL|Kataleptic Toxicology}} 13.
**{{IL|Vigilant Chitin-Fur Boots}} and an outfit with {{IL|Respectable}} 15 and {{IL| Artisan of the Red Science}} 13.
**{{IL|Special Dispensation}} (must be fighting for yourself or for order). Note that unlike the other options, this one does not have rare successes.
*In group - use BDR/Skill option 4 times, then, if needed, use [[Fight without taking your eye off the goods!]] combined with Airs options until getting to target Brawling amount.
*Solo - use BDR/Skill option 2 times, then [[Fight without taking your eye off the goods!]] 4 times, then, if needed, combine it with Airs options until getting to target Brawling amount.
EPA ranges for the various combinations:
*[[Accept a share of the extremely dusty crates]] - 13 (least-demanding)/9 (most-demanding) actions for 27.5 {{e}}. '''2.115/3.055 EPA''' (2.149/3.104 with access to {{IL|Upper River}}).
*[[Claim the extremely dusty crates]] - 14/12 actions for 40 {{e}}. '''2.857/3.333 EPA''' ('''2.902/3.386''' with access to {{IL|Upper River}}).
*[[Accept a share of the coffer of Admiralty maps]] - 11/8 actions for 25/25.5 {{e}}. '''2.272/3.187''' EPA.
*[[Claim the coffer of Admiralty maps]] - 13/12 actions for 38.5/40 {{e}}. '''2.961/3.333 EPA.'''
*[[Accept a share of the crates cleared out of Saint Cyriac's Illuminated College]] - 7/5 actions for 16/16.75 {{e}}. '''2.285/3.35 EPA.'''
*[[Claim the crates cleared out of Saint Cyriac's Illuminated College]] - 7/7 actions for 20.5/22.25 {{e}}. '''2.928/3.178 EPA.'''

===A Trade in Reputations===
*Requires {{IL|A Person of Some Importance}}
*High {{IL|Shadowy}} and {{IL|Persuasive}} is an advantage.
*High {{IL|Respectable}}, {{IL|Dreaded}} or {{IL|Bizarre}} is an advantage
*Expected EPA: '''2.8-3.3'''
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
The strength of this grind is that it has very low base requirements, but you can make it harder and more profitable if you want to.
*See [[A Trade in Reputations (Guide)]] for strategies.
Around level 270 is needed in the main attributes for max EPA, but around level 200 should reach above 2.8 EPA, and you can modify the strategy based on your strengths.
</div>

----
===Professional Activities===
*Requires a tier 3 [[Profession]]
*Stat requirements depend on Profession and player progression
*Expected EPA: At least '''3.2-4.1''', more for certain Professions and Specializations
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
See [[Professional Activities (Guide)]] for details. As the player progresses through the game and unlocks more content, more options will unlock in this wheel, causing it to grow in value over time. Certain rewards can also be exchanged for {{IL|Rat-Shilling}} or {{IL|Hinterland Scrip}}, improving profitability. 
</div>

----
===Hearts' Game===
*Minimal stat requirements
*Best with {{IL|Shadowy Gains}} 20+ and at least one of {{IL|A Complete Account of Frogs, Toads, and Other Croaking Beasts|Appearance=Complete Account of Croaking Beasts}} or {{IL|Unexpurgated Accounting of the Anatomies of Aquatic Life-forms|Appearance=Unexpurgated Accounting of Aquatic Life-Forms}}
*Expected EPA: up to '''4.73-4.87''' directly, or up to '''5.31''' using the Bone Market or '''5.36''' using Khanate horsebitrage
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
See [[Hearts' Game (Guide)]] for details. Stats have little effect on this grind, as the player earns {{IL|Hearts' Game: Exploits}} regardless of their performance in Hearts' Game. Exploits can be cashed out for various T7 items. Of particular note are the {{IL|Leviathan Frame}}, which can be profitably used in the Bone Market, and the {{IL|Scrap of Ivory Organza}}, which can be offloaded profitably at the Rat-Market.

With access to the Bone Market and the ability to create Reptile and/or Fish skeletons, the strategy for Hinterland Scrip grinding [[Hinterland Scrip-Making#The Game of Poison and Delight (a.k.a. Heart's Game)|detailed here]] can be used to generate up to 744 {{IL|Hinterland Scrip|Appearance=}} over 74 actions, or 10.05 SPA. Using {{IL|Tinned Ham}} Arbitrage this becomes 393.13 E over 74 actions, or 5.31 EPA.

With access to the Khanate, the strategy outlined in [[Money-Making/Lategame#Crackling_Trade|detailed here]] can be used on the {{IL|Salt Steppe Atlas}} gained from [[The dusty book]] to increase its EPA to 5.26.

{{GuideNeedsWork|Reason=With recent changes to the Lab, lab research is rather less predictable.

Exact calculations for the whole grind are very complicated and require [[Media:AC9863F1-0489-471E-ADE7-5034F53175D5.jpeg|a probability tree]] and a [https://docs.google.com/spreadsheets/d/1AqUye_8rkXU0PZwN-0q_YsyDsUxDJ3bVtQRSh7SKMWk spreadsheet]. Excluding unsellable items ({{IL|Moonlit}}/{{IL|Wing of a Young Terror Bird| Appearance=Wings of a Young Terror Bird}}) and amortizing travel, EPA ranges from a high of '''5.39 EPA''' with {{IL|Monstrous Anatomy}} 15 and {{IL|Bone Market Fluctuations:}} Antiquity to '''3.98 EPA''' with {{IL|Monstrous Anatomy}} 10 on non-Antiquity weeks.

Taking full advantage of {{IL|Bone Market Fluctuations:}} raises EPA at the cost of depending on RNG/stretching the profits even more long-term. It should be noted that you can't spend all your actions at such efficiency, since it takes fewer actions to gather materials than to assemble and sell a skeleton and Antiquity week on average occurs 1/3 of the time — as a result, you will need to spend some actions either on different types of activities/stories or accept the On Average EPA.

In case of other grinds/activities, you can also exclude travel actions from the grind by doing its parts while already being in Upper River/specific location for the other purpose. EPA can be improved yet further (though unreliability makes calculating exact increase impossible):
*{{IL|Favours: The Docks}} gotten from cards can be used to [[Watch a parade]], with resulting {{IL|Esteem of the Guild}} spent on trips to [[Charter a barge to the Octagonal Tomb|Octagonal Tomb]] for 2 {{IL|Human Ribcage}}s per each trip as well other items. Hold onto {{IL|Night-Whisper}}s until {{IL|The Rat-Season:}} Dimmest-Dark, Freeze-and-Fall or Lying-Longing and cash them out through [[Sell a Night-Whisper for 850 Rat-Shillings]].
* While most {{IL|Favours: Constables}} sources aren't good enough for [[A longer conversation with the Commissioner of Police]] to be better than Brawling for {{IL|Human Ribcage}}s, [[Visit him in his lodgings|visiting the Regretful Soldier]] on [[A Visit]] yields up to 5.6 {{e}} in items and {{IL|Favours: The Docks|1 x}} in addition to {{IL|Favours: Constables|1 x}}.
* If you're a member of {{IL|The Clay Tailor Club}}, the [[An Evening at the Clay Tailor's|associated card]] gives {{IL|Thirsty Bombazine Scrap}}s as well as {{IL|Jasmine Leaves}} which can be sold in bulk with a 30% markup through [[Sell all your Jasmine Leaves via the contacts of the Gracious Widow]].

It's also possible to [[Hinterland_Scrip-Making#Licentiate_Bone_Market_grind|grind for scrip]] instead of echoes. At 30 {{h}} per skeleton, after Tinned Ham Arbitrage this gives '''3.81 EPA''', not counting AP spent on travel.

==Upper River Grinds==

===Moulin Expeditions===
*Expected EPA: '''3.97 to 4.71'''
'''Requirements'''
*Access to {{IL|Moulin}}
*{{IL|Kataleptic Toxicology}} 8 and {{IL|Transfixing Squirrel}} is an advantage
*{{IL|Shapeling Arts}} 10 is an advantage.
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
Take the [[A Bandaged Navigator on your Expedition|Bandaged Navigator]] and [[A Renegade Claw on your Expedition|Renegade Claw]] with you, equipping a [[Kataleptic Toxicology Items|Kataleptic Toxicology item]], up to 3 [[Shapeling Arts Items|Shapeling Arts items]] and as much [[Stat-reducing items|Persuasive-reducing stuff]] as possible if you have a [[Transfixing Squirrel]]. If you don't have a [[Transfixing Squirrel]], instead equip up to 3 [[Shapeling Arts Items|Shapeling Arts items]] and as much [[Shadowy Items|Shadowy stuff]] as you can. While on the expedition, play any [[A Lesser Find]] cards you get, use obstacle cards to get out to [[Moulin: Distance Traversed|Distance]] 8 before digging and heading back, making up any shortfall in supplies with [[Convince your team to keep going]]. For a list of which obstacle cards to play, and the order of preference for them (as well as a more detailed explanation of the grind more generally) see [[Moulin Expeditions (Guide)]].

This gives an EPA of between '''4.18''' and '''4.43''' depending on what equipment you have. If combined with writing Exceptional Monographs, which for 9 actions and 75 echoes worth of expedition materials give 119.5 echoes worth of various resources, EPA rises. If you can 100% relevant challenges (require {{IL|Mithridacy}} 10/12, {{IL|Glasswork}} 10 or {{IL|Artisan of the Red Science}} 10 depending on challenge), it gives an EPA of between '''4.59''' and '''4.70'''.

Each subcycle yields 28 CP {{IL|Casing...}}, so repeating 9 times is 252 CP {{IL|Casing...}} for 36 actions.
#<li value="2">Enter {{IL|A hidden camp nestled in the woods of Balmoral}}.</li>
#Do seven second-tier larcenies.
#*The option on the [[Larceny at Balmoral]] card ([[Ambush a courier]]) is the most profitable, yielding {{e}}25.4 from the {{IL|Vital Intelligence|2 x}} after Tinned Ham Arbitrage.
#*The next best choices are on the [[Larceny at Jericho Locks]] card ([[Seize a jewel smuggler's boat]]) and the [[Larceny at the Magistracy]] card ([[Break into the offices of Baseborn & Fowlingpiece]]), both yielding {{e}}25 of items.
#*Ignore the cards for larcenies in Ealing Gardens ({{e}}24.4) and/or Burrow-Infra-Mump ({{e}}22).

Total payout depends on how often can you draw [[Larceny at Balmoral]]. Without Burrow, this happens 1/2 of the time: the average payout is 25.2 {{e}} per larceny, or 176.4 {{e}} for 43 actions, a total of '''4.10 EPA'''.

With Burrow, this happens 1/3 of the time: the average payout is 25.13{{e}} per larceny, or 175.93 {{e}} for 43 actions, a total of '''4.09 EPA'''.

*Enter with [[Just the right person]]
*[[Deploy your Morally and Physically Flexible Rubbery Cat]] 2 times
*Watch a Rubbery Calligraphist (option in The Sculpture Garden) 2 times
*[[Forget the biscuits, take the Solacefruit]]

6 actions for {{IL|Intriguing Snippet|3 x}} (0.6 echoes), {{IL|Extraordinary Implication|2 x}} (5 echoes), {{IL|Solacefruit|20 x}} ({{IL|Hinterland Scrip|20 x}} or 10.16 echoes), 14 CP {{IL|Casing...}}, 2 CP {{IL|Fascinating...}} and 2 CP {{IL|Investigating...}}. Since you can spend 36 CP in one action for ~25.13 echoes (as outlined in Parabolan Larcenies above), 14 CP Casing can be abstracted as additional 0.38 actions/9.774 echoes. Every 104 loops, you Show your Pendant of Helicon Amber at the door, enter with [[No one!]], use one of +3 {{IL|Fitting in at Helicon House}} options ([[Join in with a Rubbery Euphonium]], [[Contribute some extra practitioners]], [[Encourage the Boneless Pianist to join in]]) and [[Attract a companion for the rest of the evening]], spending 208 CP and three actions for 70.06 echoes - therefore, 2 CP Fascinating can be abstracted as additional 0.028 actions and 0.673 echoes. Since Investigating lacks good cash-outs, 2 CP Investigating can be disregarded.

Total - (6 + 0.38 + 0.028) 6.408 actions for (0.6 + 5 + 10.16 + 9.774 + 0.673) 26.207 echoes. '''4.089 EPA'''. (Discounting actions spent on travel, since {{IL|Casing...}} can be stockpiled indefinitely.)

===Holding your breath in the Hurlers===
'''Requirements:'''
*Access to {{IL|The Hurlers}}
*Preferably {{IL|Dangerous}} 317
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
Requires high {{IL|Dangerous}}, and access to [[The Hurlers]], the eighth station of the Railway. Relies on {{IL|Hurlers: Darkness}} manipulation and [[Hold your breath underwater|holding your breath underwater]], plus requires {{IL|Correspondence Plaque|Appearance=Correspondence Plaques}}. Generates large amounts of {{IL|Final Breath}} for Tinned Ham Arbitrage. ([https://www.reddit.com/r/fallenlondon/comments/n2h70h/holding_your_breath_in_the_hurlers_5_epa/gwkgcfs/?utm_source=share&utm_medium=web2x&context=3 '''Source'''])

#Start with [[Stoking the Stove]] 1 and 7 Darkness (this is the state immediately after bringing the stove back to the station).
#[[Add more plaques to the stove]] 9 times (this drops Darkness to 1 + 0 CP and raises Stoking the Stove to 4 + 0 CP). This costs 9 actions and 63 Correspondence Plaques.
#Perform the following loop 9 times:
##[[Hold your breath underwater]] (raises Darkness to 2 + 0 CP). This costs 1 action and gains 22 Breaths. (Holding your breath underwater gives an amount of Final Breath dependent on Darkness)
##Add more plaques to the stove (drops Darkness to 0, raises Stoking the Stove by 1 CP). This costs 1 action and 7 Plaques.
##Hold your breath underwater twice. The first time gets you 23 Final Breaths (0 Darkness), the second gets you 22. This costs 2 actions and gains 45 Final Breaths (it also raises Darkness to 2 + 1 CP)
##Add more plaques to the stove (drops Darkness to 1 + 0 CP, raises Stoking the Stove by 1 CP). This costs 1 action and 7 Plaques.
#Each iteration of the loop costs 5 actions and 14 Plaques, raises Stoking the Stove by 2 CP, and gains 67 Breaths. So, performing 9 iterations costs 45 actions and 126 Plaques, raises Stoking the Stove to 7 + 0 CP and gains 603 Breaths.
#Hold your breath underwater 14 times.
##The first time gives 22 Final Breaths (1 Darkness)
##The second and third give 21 Breaths (2 Darkness)
##The fourth and fifth give 19 Breaths (3 Darkness)
##The sixth and seventh give 16 Breaths (4 Darkness)
##The eighth to tenth give 12 Breaths (5 Darkness)
##The eleventh to fourteenth give 8 Breaths (6 Darkness)
#In total, this costs 14 actions and gains 202 Breaths.
#[[Add more plaques to the stove 2|Add more plaques to the stove]]. Since you now have Stoking the Stove 7, this sets it to 8. This also gives 2 CP of Scandal (Tracklayers' Displeasure is ignored, since its effects are insignificant). This costs 1 action and 7 Plaques.
#Now you need to hunt the stove down. This is technically card-dependent, but it's a 10x frequency card in a smaller deck so you shouldn't have much trouble. If you succeed all the checks, this costs 4 actions and gets you 5E worth of bats. This returns you to where you started, with 7 Darkness and Stoking the Stove 1.

In total you spend 73 actions and 196 Plaques for 805 {{IL|Final Breath|Appearance=Final Breaths}} (which are worth 408.94E when we convert via {{IL|Tinned Ham}}) and 5E. 

In order to make this a self-contained grind, the necessary {{IL|Correspondence Plaque|Appearance=Correspondence Plaques}} must be obtained from somewhere. The best way to get them is by publishing [[A gossipy and tantalising edition|Salacious newspapers]] with all of the special options for {{IL|Journal of Infamy|Appearance=Journals of Infamy}} (the {{IL|Scrap of Incendiary Gossip|Appearance=Scraps of Incendiary Gossip}} needed for the social action can be obtained by publishing [[Publish a seditious edition|seditious editions]]: see [[Publishing a Newspaper (Guide)]] for more details) and cross-converting them. Doing this gets you ~6.76 Plaques per action, so obtaining the 196 Plaques necessary costs 28.98 actions (101.98 actions total).

However, this grind involves a number of difficult {{IL|Dangerous}} checks. [[Hold your breath underwater]] has difficulty 190 (needs 317 {{IL|Dangerous}} to 100%), and bringing the stove back requires succeeding a difficulty 280 check 3 times (impossible to 100%), though this can be substituted with a difficulty 310 {{IL|Shadowy}} check (not considered here). The final EPA is calculated for two different {{IL|Dangerous}} values: '''317''' (minimum to 100% the [[Hold your breath underwater]] check - technically obtainable, but out of reach for most characters) and '''288''' (maximum obtainable without mood/fate/ambition/profession/destiny/spouse/club items). Menaces must also be taken into account - it is assumed here that all menaces are cleared at 6 CP per action using social actions.

With '''317''' {{IL|Dangerous}}, the difficulty 190 check on [[Hold your breath underwater]] never fails, and the difficulty 280 check on [[Challenge it with your fists]] succeeds 67% of the time. Since you need three successes, the expected number of failures is 1.478. Each failure incurs 3 CP of Wounds and each success incurs 1 CP, so the expected amount of Wounds incurred is 7.432 CP. You also get 2 CP of Scandal when the stove escapes, so in total the expected number of actions spent clearing menaces is 1.572. The final action cost is therefore 105.03, for '''3.94 EPA'''.
*If you are a {{IL|Monster-Hunter}}, you can [[Spear it with your harpoon]] instead of trying to pass Dangerous challenge to capture the stove. While this adds 2 actions, it also removes actions spent on failing challenges (-1.478), clearing Wounds (-1.238), and grinding {{IL|Correspondence Plaque|Appearance=Correspondence Plaques}} - each spearing gives 2 on average, so per five spearings you get 10 total, removing 1.47 actions. The final action cost is therefore 102.84, for '''4.02 EPA'''.

With '''288''' {{IL|Dangerous}}, the [[Hold your breath underwater]] check has a 90% success chance, and the [[Challenge it with your fists]] check has a 61% success chance. You need 37 successes when holding your breath, so the expected number of failures is 4.111 (incurring 8.222 CP of Wounds). You need 3 successes when bringing the stove back, so the expected number of failures is 1.918 (incurring 5.754 CP of Wounds from failures, and 3 CP from successes). The expected number of actions spent on menace reduction is 3.163, and the final action cost is 111.17, for '''3.72 EPA'''.
*If you are a {{IL|Monster-Hunter}}, you can [[Spear it with your harpoon]] instead of trying to pass Dangerous challenge to capture the stove. While this adds 2 actions, it also removes actions spent on failing challenges (-1.478), clearing Wounds (-1.238), and grinding {{IL|Correspondence Plaque|Appearance=Correspondence Plaques}} - each spearing gives 2 on average, so per five spearings you get 10 total, removing 1.47 actions. The final action cost is therefore 108.98, for '''3.79 EPA'''.

===Selling very advanced identities===

The main idea of this grind is making a cover identity with maximum nuance, credentials, witnesses and elaboration and 500 points of backstory. The biggest part of this grind is grinding {{IL|Mortification of a Great Power|20 x}} in the Sunken Embassy, so watchful is definitely the most important stat in this grind. 
*Begin with going [[Eastward]] or [[Westward]] in [[Seeking Documents in the Sunken Embassy]]
*[[Seek out spy-holes]] 16 times.
*Then go out and [[Send an inordinately enormous stack of documents to Mount Palmerston]] Repeat these steps until you have {{IL|Mortification of a Great Power|20 x}}. You will also accrue some {{IL|Lump of Lamplighter Beeswax}}, 1600 to be exact.
*Go to [[All aboard!]] and [[Take the sleeper all the way to Balmoral]]
*Go into your {{IL|Cabinet Noir}} and [[Begin to construct a cover identity]] until you have 10 elaboration. Assuming {{IL|Shadowy|300 x}} this should take 10.97 actions on average.
*[[Endow your cover identity with eccentricities]] 6 times
*[[Make sure your cover identity has been observed in the right quarters]] 6 times
*[[Credential your cover identity]] 6 times.
*[[Embed your cover identity in the story of a terrible humiliation]] 20 times
*Play the card [[Halfway to Hell]] and choose to [[Sell a very advanced identity to Devils]] or the card [[The Railway and the Great Game]] and choose to [[Sell a very advanced identity to Spies]]. Selling to devils also loses 4 favours (but does not require them), so the great game option is likely better. 
*[[Make a leap of code-breaking insight]] 18 times and [[Interpret your Intercepted Document]].
This should take 429.97 actions for an item worth 1560 echoes and 16 echoes in beeswax, so '''3.67 EPA'''.

----
===Deciphering Documents===
Expected EPA: Up to '''3.86'''
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
After reaching {{IL|Balmoral}} and setting up a {{IL|Cabinet Noir}}, you can intercept documents and decipher them for various rewards - it's recommended to have at least {{IL|A Player of Chess}} 7, {{IL|Watchful}} 292 and {{IL|Shadowy}} 300, and for maximum efficiency you need to be a {{IL|Midnighter}}. The main documents sources are:
*[[Intercept a piece of post]]: This has a 60/40 chance of giving a document with either {{IL|Vital Intelligence|1 x}} ({{IL|Hinterland Scrip|25 x}}/12.7 {{e}}) or {{IL|Blackmail Material}} (12.5 {{e}}) as a reward. However, since it's currently impossible to 100% the Shadowy challenge, with Shadowy 300 you have a 10% chance of failure, which gives a document with {{IL|An Identity Uncovered!|1 x}} and {{IL|Scrap of Incendiary Gossip|18 x}} (11.5 {{e}} in total) as a reward. Therefore, the reward spread is actually 54/36/10 for 12.7/12.5/11.5 respectively, averaging to 12.508 {{e}}. All these documents require {{IL|Deciphering...}} 5.
*[[Intercept a message (Balmoral Kitchens)|Intercept a message]]: This requires {{IL|Balmoral: Darkness}} to 100% the Shadowy challenge and gives a document with {{IL|Night-Whisper|1 x}} (62.5 {{e}}) as a reward. However, to access this action you first need to [[Seek admittance]] and then [[Sneak down to the Kitchens of Balmoral]] - this Shadowy challenge isn't currently 100%-able. With Shadowy 300 you have a 15% chance of failure which wastes an action and gives 2 CP {{IL|Suspicion}}, meaning that on average you spend 3.15 actions in total and get 0.3 CP Suspicion. This document requires {{IL|Deciphering...}} 15.
*[[Steal a curious document from the Tracklayers' Office]]: This requires {{IL|Following up Rumours of Cornelius}} 3 and gives a document with {{IL|Primaeval Hint|1 x}} (62.5 {{e}}) as a reward. However, since it's currently impossible to 100% the Shadowy challenge, with Shadowy 300 you have a 10% chance of failure which wastes an action and gives 2 CP {{IL|Suspicion}}, meaning that on average you spend 1.1 action and get 0.2 CP Suspicion. This document requires {{IL|Deciphering...}} 15.
There are two ways to earn {{IL|Deciphering...}}, both more efficient if you're a Midnighter:
*[[Crack a code]]: This requires {{IL|Watchful}} 292 and {{IL|A Player of Chess}} 7 to 100%, and gives 5/6 CP.
*[[Make a leap of code-breaking insight]]: This requires {{IL|Watchful}} 292 and {{IL|A Player of Chess}} 10 to 100%, and gives 7/9 CP (rare success not counted).
For dealing with Suspicion you need to earn {{IL|Disappearing...}} through covering your tracks (which is also more efficient if you're a Midnighter), with 5/6 CP per action. As [[Eliminate a good deal of suspicion]] action requires 11/10 additional actions to earn Disappearing... 10 and eliminates 33 CP, 1 CP Suspicion can be abstracted as 0.36/0.33 actions. Therefore, EPA of deciphering depends on specific document, your {{IL|A Player of Chess}} level and whether you're a Midnighter:
*[[Intercept a piece of post]] requires 1 action to start, 3/2 actions to decipher, and 1 action to finish, with a total of 5/4 actions for 12.508 {{e}}. '''2.5026/3.127 EPA'''.
*[[Intercept a message (Balmoral Kitchens)|Intercept a message]] requires 3.258/3.249 actions to start, 24/20/18/14 actions to decipher, and 1 action to finish, with a total of 28.258-18.249 actions for 62.5 {{e}}. '''2.211-3.424 EPA'''.
*[[Steal a curious document from the Tracklayers' Office]] requires 1.172/1.166 actions to start, 24/20/18/14 actions to decipher, and 1 action to finish, with a total of 26.172-16.166 actions for 62.5 {{e}}. '''2.388-3.866 EPA'''.
</div>

----
===Marigold Emblems===
Expected EPA: '''3.76 EPA'''
*Expects main attributes at 300
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
After reaching {{IL|Marigold Station}} you can take commissions from Gnarled Stationmaster (or, if he's replaced by Cerise Condottiere, from him - mechanically they're identical) for various rewards. For maximum efficiency you need to have {{IL|Persuasive}}, {{IL|Watchful}} and {{IL|Dangerous}} all at 300, {{IL|Jericho Library}} 2, and clear menaces using social actions, at 6 CP per action. Steps:
*[[Accept another commission]]
*Depending on {{IL|The Marigold Bearer's Fate}}, [[Carve out the emblem]], [[Scour the earth]] or [[Coax out the Knight]]
*[[Return the Marigold]]
With 90% chances on all challenges, on average you spend 3.1 actions and gain 0.8 CP Menaces for (again, depending on {{IL|The Marigold Bearer's Fate}}) {{IL|Verse of Counter-Creed}}, {{IL|Cave-Aged Code of Honour}} or {{IL|Brass Ring}}. Per 15 emblems on average you spend 46.5 actions and gain 12 CP Menaces for {{IL|Verse of Counter-Creed|5 x}}, {{IL|Cave-Aged Code of Honour|5 x}} (62.5 {{e}}) and {{IL|Brass Ring|5 x}} (62.5 {{e}}). With two additional actions spent clearing Menaces and five spent [[Lend religiously|cashing out]] Verses for {{IL|Hinterland Scrip|150 x}} (76.2 {{e}}), the full cycle is 53.5 actions for 201.2 {{e}}. '''3.76 EPA'''. (Discounting actions spent on travel, since Verses can be stockpiled indefinitely.)

If you have 334 in one of the stats and therefore have 100% chance on one of the challenges, on average you spend 3.06 actions and gain 0.53 CP Menaces per emblem. Per 600 emblems on average you spend 1836 actions and gain 318 CP Menaces for {{IL|Verse of Counter-Creed|200 x}}, {{IL|Cave-Aged Code of Honour|200 x}} (2500 {{e}}) and {{IL|Brass Ring|200 x}} (2500 {{e}}). With 53 additional actions spent clearing Menaces and 200 spent [[Lend religiously|cashing out]] Verses for {{IL|Hinterland Scrip|6000 x}} (3048 {{e}}), the full cycle is 2089 actions for 8048 {{e}}. '''3.85 EPA'''.

If you have {{IL|A Submerged Rector}} you can draw cards in Upper River and boost EPA somewhat, cashing out Verses partially (since you probably can't draw enough cards for them all) through [[Noisily subvert the entire process]] for 36 instead of 30 Scrip per Verse.

===Ealing Spa===
Expected EPA: '''3.02'''
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
Since basic options are included in Simplest Endgame Grinds, this grind describes how to get the absolute most from the spa.
*For [[Attend for a treatment|attending a treatment]] you need to be a Spirifier. On average you get 1.875 echoes in {{IL|Brilliant Soul}}s and {{IL|Compromising Document}}s in addition to 50 {{IL|Soul}}s per action. Spirifiers can exchange 1000 {{IL|Soul}}s for 3000 {{IL|Nevercold Brass Sliver}}s and 2 {{IL|Appalling Secret}}s in one action, for a total of 30.3 echoes. In 21 actions, ignoring travel (since souls can be stockpiled indefinitely), you get 67.8 echoes - '''3.228''' EPA.
*For [[Offer to design a treatment: a steam-bath of Mutersalt Vapours|offering a treatment]], besides {{IL|Mutersalt}} and {{IL|Kataleptic Toxicology}} 10, you need to have [[Put up a statue honouring Virginia, former Mayor and current Board Member|built the Virginia statue]]. With 5% chance of rare success, per 40 actions you get 190 {{IL|Brilliant Soul}}s (95 echoes), two {{IL|Silent Soul}}s (25 echoes) and two {{IL|Favours: Hell}}. Considering the small deck in Upper River, it can be assumed that you will draw the [[Under the Statue|statue card]] often enough to turn in all favours, spending one action to turn in two favours for 16.25 echoes on average (50/50 split between 12.5 and 20 echoes). 41 actions for 136.25 echoes - '''3.32 EPA'''.
**If you don't have a statue, you can still cash in favours through [[A soothing sight]]. 140 actions for 665 {{IL|Brilliant Soul}}s (332.5 echoes) 7 {{IL|Silent Soul}}s (87.5 echoes) and 7 {{IL|Favours: Hell}}. 2 traveling actions for a {{IL|Rumour of the Upper River}} (2.5 echoes). 7 cashing in actions for 2940 {{IL|Nevercold Brass Sliver}}s (29.4 echoes). 149 actions for 451.9 echoes - '''3.03 EPA'''.

===Eversmoulder Trips===
Expected EPA: '''3.215'''
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
After reaching {{IL|Jericho Locks}} and raising {{IL|A Member of the Gondoliers}} to 6, you can convert various resources into {{IL|Esteem of the Guild}} and spend it on trips to various destinations. Most profitable destination is the Eversmoulder, on average giving {{IL|Primaeval Hint|1 x}} (62.5 {{e}}), {{IL|Uncanny Incunabulum|2.5 x}} (31.25 {{e}}) and {{IL|Moves in the Great Game|18 x}} (9.144 {{e}}) for a total of 102.894 {{e}}. If you are a {{IL|Crooked-Cross}}, not a {{IL|Lyon Pursuivant of Arms Extraordinary}} and have unlocked Parabolan War, the following loop is possible:
*[[Enter the Palatinate alone (Restored, no Lyon)|Enter the Palatinate alone]] 24 times
*[[Debate with the Nostalgic Landlady]] 6 times
*[[Charter a barge to the Eversmoulder]]
*[[Leave the barge (The Eversmoulder)|Leave the barge]]
32 actions for 102.894 {{e}}. '''3.215 EPA'''.

Alternatively, if you're gaining Esteem through [[Watch a parade]], getting favours at roughly one per action rate from cards in London or Moulin (with {{IL|Moulin Commemorative Development}} exactly 22) and traveling to Jericho every time you accumulate 5, you spend 15 actions getting favours, 3 watching parades, 6 traveling (gaining additional 15 {{e}} from {{IL|Rumour of the Upper River|6 x}} and 2 on trip itself. 26 actions for 117.894 {{e}} - '''4.534''' EPA.

Require a [[Ship]].
===Khaganian Intrigue===
*Expected EPA: '''4.1''' (5.10 with Rat Market)
*Requires access to {{IL|Khan's Heart}}
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
By setting up a Cover Identity and zailing across the zee, you can play a number of Intrigues at [[Khan's Heart]] - however, you need to ensure that your Cover Identity and your chosen outfit permits you to 100% the challenges to increase you Intrigue in all hours in the Khanate day cycle. See the [[Khaganian Intrigue (Guide)|guide]] for details on such outfits. The main intrigues for earning money are:
*[[Sabotage a power plant]]: This requires {{IL|Colour at the Chessboard}} 1-2, costs {{IL|Intercepted Cablegram|5 x}}, takes 77 actions (1 to start, 75 to progress, 1 to finish), and yields {{IL|Night-Whisper|5 x}} (312.5 {{e}}) + 10 CP {{IL|Advancing the Liberation of Night:}}.
*[[Plant a mirror]]: This requires {{IL|Connected: Fingerkings}} 4, costs {{IL|Intercepted Cablegram|2 x}}, takes 15 actions (1 to start, 13 to progress, 1 to finish), and yields {{IL|Oneiromantic Revelation|1 x}} (62.5 {{e}}) + {{IL|Favours: Fingerkings|1 x}}.
*[[Expand your network: Recruit (Agent)|Expand your network]]: This costs {{IL|Intercepted Cablegram|2 x}}, takes 15 actions (1 to start, 13 to progress, 1 to finish), and yields a T6 item - which one depends on a specific agent/{{IL|Airs of the Khanate}} range. Academic, Thief and Diplomat give {{IL|Searing Enigma}}, {{IL|Crackling Device}} and {{IL|Bottle of Fourth City Airag: Year of the Tortoise}} respectively, each worth 62.5 {{e}}. Dissident gives {{IL|Stalemate}} worth 125 {{IL|Hinterland Scrip|125 x}} (63.5 {{e}}). Tailor and Engineer give {{IL|Much-Needed Gap}}, and Physician gives {{IL|Oneiric Pearl}}, each worth {{IL|Assortment of Khaganian Coinage|125 x}}. Since you can buy {{IL|Crackling Device}} for 130 coinage, 125 can be abstracted as 60.096 {{e}}. Aristocrat, Officer and Soldier give {{IL|Mortification of a Great Power}}. Currently, it can only be cashed out though [[Cover Identities (Guide)|Cover Identities]], spending to gain {{IL|Cover Identity: Backstory|26 x}} with [[Embed your cover identity in the story of a terrible humiliation]] option. Simplest way is to just [[Fence this identity]], which gives {{IL|Magnificent Diamond|1 x}} per 5 backstory points (essentially 2.5 {{e}} per 1 point). Since there’s no cap on backstory, the actions/additional rewards for raising Elaboration/fencing can be removed from calculation, and cashout can be abstracted as 1 action/65 {{e}} per Mortification. Therefore, on average you spend additional 3 actions and gain 626.288 {{e}} per 10 agents/0.3 actions and 62.6288 {{e}} per 1 agent. Also, any recruited agent raises {{IL|Strength of your Khaganian Network}} by 1.

All of these intrigues cost {{IL|Intercepted Cablegram}}s, and there are two ways to get those:
*[[Intercept a cablegram]]: This takes 4 actions (1 to start, 2 to progress, 1 to finish) and yields {{IL|Intercepted Cablegram|5 x}} + {{IL|Vital Intelligence|1 x}} worth 25 {{IL|Hinterland Scrip}} (12.7 {{e}}).
*[[Tap a telegraph cable]]: This requires {{IL|Strength of your Khaganian Network}} 10, takes 15 actions (1 to start, 13 to progress, 1 to finish), and yields {{IL|Intercepted Cablegram|50 x}} + {{IL|Vital Intelligence|1 x}} worth 25 {{IL|Hinterland Scrip}} (12.7 {{e}}) + either {{IL|Queen Mate|1 x}} or {{IL|Epaulette Mate|1 x}}, both worth 50 {{IL|Hinterland Scrip}} (25.4 {{e}}).

Possible combinations include:
*[[Intercept a cablegram]] - 4 actions yielding {{IL|Intercepted Cablegram|5 x}} + 12.7 {{e}}. [[Sabotage a power plant]] - costs {{IL|Intercepted Cablegram|5 x}}, takes 77 actions, and yields 312.5 {{e}}. In total - 81 actions, yielding 325.2 {{e}}, which is '''4.015 EPA'''.
*[[Tap a telegraph cable]] - 15 actions yielding {{IL|Intercepted Cablegram|50 x}} + 38.1 {{e}}. [[Sabotage a power plant]] 10 times - costs {{IL|Intercepted Cablegram|50 x}}, takes 770 actions, and yields 3125 {{e}}. In total - 785 actions, yielding 3163.1 {{e}}, which is '''4.029 EPA'''.
*[[Intercept a cablegram]] twice - 8 actions yielding {{IL|Intercepted Cablegram|10 x}} + 25.4 {{e}}. [[Plant a mirror]] 5 times - costs {{IL|Intercepted Cablegram|10 x}}, takes 75 actions, and yields 312.5 {{e}}. In total: 83 actions, yielding 337.9 {{e}}, which is '''4.071 EPA'''.
*[[Tap a telegraph cable]] - 15 actions yielding {{IL|Intercepted Cablegram|50 x}} + 38.1 {{e}}. [[Plant a mirror]] 25 times - costs {{IL|Intercepted Cablegram|50 x}}, takes 375 actions, and yields 1562.5 {{e}}. In total: 390 actions, yielding 1600.6 {{e}}, which is '''4.104 EPA'''.
*[[Intercept a cablegram]] twice - 8 actions yielding {{IL|Intercepted Cablegram|10 x}} + 25.4 {{e}}. [[Expand your network: Recruit (Agent)|Expand your network]] 5 times - costs {{IL|Intercepted Cablegram|10 x}}, takes 76.5 actions, and yields 313.144 {{e}}. In total: 84.5 actions, yielding 338.544 {{e}}, which is '''4.006 EPA'''.
*[[Tap a telegraph cable]] - 15 actions yielding {{IL|Intercepted Cablegram|50 x}} + 38.1 {{e}}. [[Expand your network: Recruit (Agent)|Expand your network]] 25 times - costs {{IL|Intercepted Cablegram|50 x}}, takes 382.5 actions, and yields 1565.72 {{e}}. In total: 397.5 actions, yielding 1 603.82 {{e}}, which is '''4.034 EPA'''.

With {{IL|Strength of your Khaganian Network}} 20, [[An opportunity: (Opportunity)]] becomes available, which takes {{IL|Emetic Revelation|1 x}} (12.5 {{e}}) and can yield 62.5 {{e}} worth of items for 12 actions for ideally '''4.17 EPA'''. The upside of this method is that the sequence of Opportunities is deterministic and [[Khaganian Intrigue (Guide)/Opportunity cycles|good cycles]] exist which only give you sellable items. The downside is that you need {{IL|Emetic Revelation}}s to do this. If you grind them by using options which yield Khanite currency, convert that into light bulbs and sell these in London, one Revelation will take about 3.66 actions. This will lower the efficiency of that grind to just about '''4 EPA'''.

===The Court of the Wakeful Eye===
After completing [[Associating with Radical Academics]] storyline, [[Offering Tribute to the Court of the Wakeful Eye|The Court of the Wakeful Eye]] lets you exchange various Favours and items for {{IL|Tribute}}, up to 260. [[Zailing_(Guide)|Zailing]] to the Court takes 6 actions, and returning to London takes 8 if you use {{IL|Zubmarine}} or {{IL|Majestic Pleasure Yacht}}/7 if you use {{IL|Swift Zee-Clipper}} or {{IL|The Cladery Heart}}, for a total of 14/13 actions per trip. At the Court, 20 Tribute can be exchanged for 62.5 {{e}} worth of items in 4 actions, up to 812.5 {{e}}/52 actions per trip. The most efficient strategies are:

*Every time you have 7 favours of the same faction, exchange them for 23 Tribute. Assuming 1 action/card per Favour, you get 241-263 Tribute in 88 actions, depending on leftovers from previous trips.
*Zail to the Court in 6 actions.
*Turn 260 Tribute into 812.5/875 {{e}} worth of items in 52/56 actions, depending on whether the tribute 260 or more.
*Return in 8/7 actions. 
The 260 Tribute case occurs in 4/20 or 1/5 cases, so on average 147.8/148.8 actions for 825 {{e}} - '''5.54/5.58 EPA'''. Options which give more than 1 Favour per action and/or give additional profit (e.g. [[A Visit]], [[More Larks with the Young Stags]], [[The Calendrical Confusion of 1899]], fate-locked Restoring souls from [[A Trade in Souls]], [[The Tower of Eyes: Behind Closed Doors at a Handsome Townhouse|The Tower of Eyes]] if you have [[Augmented Electrostatic Machine]], professional payments, etc.) will increase the EPA further, while options that consume items and/or give menaces (faction cards, for example) will lower the EPA.

*[[Recognise an opening because of your professional affiliations]]
*[[Open with a familiar move]]
*[[Play a move you learned from the Boatman]] 5 times
*[[Choose an epaulette mate]] or [[Choose a queen mate]]
9 actions for a {{IL|Vienna Opening}} (5 {{IL|Hinterland Scrip}}), mate (50 {{IL|Hinterland Scrip}}) and 138 {{IL|Well-Placed Pawn}}s. Per 60 cycles you spend 540 actions for 3300 {{IL|Hinterland Scrip}} and 8280 {{IL|Well-Placed Pawn}}s.

Spending cycle:
*[[Remain current Colour]]
*[[Recognise an opening because of your professional affiliations]]
*[[Open with a familiar move]]
*[[Sabotage your side]]
*[[Play a move you learned from the Boatman]] 4 times
*[[Force a Stalemate]] (+125 scrip, -360 pawns)
9 actions and 360 {{IL|Well-Placed Pawn}}s for a {{IL|Vienna Opening}} (5 {{IL|Hinterland Scrip}}) and a {{IL|Stalemate}} (125 {{IL|Hinterland Scrip}}). Per 23 cycles you spend 207 actions and 8280 {{IL|Well-Placed Pawn}}s for 2990 scrip.

With 60 gathering and 23 spending cycles you have no leftover pawns, spending 747 actions for 6290 Scrip/3195.32 echoes - '''4.277 EPA.'''

If you are NOT a {{IL|Midnighter}}, the value is lessened somewhat at {{IL|A Player of Chess}} 13: you lose the Vienna Opening and gain 10 (for a total of 148) Well-Placed Pawns. At 90 cycles (810 actions), get 4500 {{IL|Hinterland Scrip}} (in Queen and Epaulette mates) and 13320 {{IL|Well-Placed Pawn}}s. Spending cycles (37 of them) are 333 actions and 37 {{IL|Stalemate}}s worth 4625 scrip. 1143 actions for 9125 Scrip/4635.5 echoes yields '''4.055 EPA''' (7.983 SPA). This decreases with less aPoC; 12 aPoC gives '''4.026''' EPA (7.925 SPA). [NOTE: If you find the loss (or gain) of {{IL|Advancing the Liberation of Night}} distasteful, you can use the Endgame 'Betray' action to switch to the opposite side. You can stay on those pieces as long as you want--the AtLoN check won't apply.]

===Parabolan War===
The strategy for Parabolan wars is complicated, and you're recommended to check [[Parabolan War (Guide)]] for a calculator to find your specific EPA. The profitability is boosted by doing the Cat campaign and selling the Parable on the rat market.

Based on the default calculator at end-game stats, this should reach at least '''5.4 EPA''' with the rat market.

===Waswood Shore===
'''Requirements'''
*Access to {{IL|The Waswood}}
*That's it! No skills!
'''Expected EPA: 3+'''
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
Repeatedly [[Reach towards the shore 2|Reach towards the shore with Airs 50+]]. Note that Airs can be shuffled at no action cost by leaving and returning to the Waswood, so it is not necessary to take the less profitable option.

Specifically, this stated EPA depends on the probability of rare success getting the [[Bottle of Fourth City Airag: Year of the Tortoise|Airag]]. Then we can calculate the expectation, so let's do the math!

Firstly, we assume that the probability of the normal failure and alternative failure are equal (25% each, for an overall failure rate of 50%), and also thusly that the game's stated overall failure/success probability of 50% is in fact true. We will also assume no value for Expertise of the 2nd/4th city ([[User:Druut|the writer]] pulls the old "leaving that as an exercise to the reader" trick), but they do have some value in the lab. Now, since we don't know the true rate of rare success, we assign it the variable <math>x</math>, representing the percent chance of rare success (overall—NOT the probability that a given success will be rare [though that should in this case just be <math>2x</math>]), which makes the probability of a normal success (0.5 - <math>x</math>).

Now, we consider the values of each outcome by their sell values:

*normal failure: 0.45 {{E}}, with a probability of 0.25
*alt failure: 0.95 {{E}}, with a probability of 0.25
*success: 5 {{E}}, with a probability of (0.5 - <math>x</math>)
*rare success: 62.5{{E}}, with a probability of <math>x</math>

This gives us an expectation <math>EPA_{reach2}= (0.25)(0.45 E) + (0.25)(0.95 E) + (0.5-x)(5E) + x(62.5E)</math>

If only there was a way to visualize how our EPA changed with different values of <math>x</math> numbers... Oh right, graphing! From [https://www.wolframalpha.com/input?i=plot+%280.5%29%280.53%29+%2B+%28x*62.5%29+%2B+%28.50-x%29%285%29+for+x%3D%5B0..0.05%5D this plot] we can see the following results:

*Without any Airag at all, this generates an expected 2.765 EPA
*This hits 3 EPA at ~0.4% rare success rate.
* At 1% rare success, we get 3.34 EPA. At 2%, 3.915 EPA. 3%, 4.49 EPA! (These higher probabilities are likely not the case, however—more data is needed.)

It's important to note that it does cost an action to enter as well as 100/50 drops of honey, so when calculating your final EPA, you'll need to multiply by a factor of <math display="inline">\frac{N}{N+1}</math> where <math>N</math> is your actions spent reaching, then subtract your personal honey cost. You also don't have access to any cards, which can be significant depending on your goals and playstyle. 

Ultimately, we really need a large sample size to determine the small mystery probability and until that data is collected, it's hard to say just how profitable this should be. It's important to remember that even with an expectation of some EPA, it is just that—an expectation: while one <i>can</i> expect to approach that number if you try enough times, it can take a very long (technically infinitely long) to reach it. This is ultimately still an RNG grind, and some will be luckier than others. So while this analysis was prompted by my annoyance at the vagueness of the stated "3+" expected EPA, I now believe that it's possibly in fact the best way to succinctly present the results. Go figure. 

Still, this has the potential to be a very simple, very profitable grind especially for those like [[User:Druut|me]] who have very middling stats (low 100s), unlocked parabola quickly before anything else, and are basically flat broke. </div>

==Rat Market Grinds==
{{HasGuide|GuidePage=The Rat Market (Guide)}}These grinds require efficiently obtaining items that can be sold at the {{IL|The Rat Market (Area)|Appearance=Rat Market}} for {{IL|Rat-Shilling|Appearance=Rat-shillings}} at a better rate than their sell price elsewhere. Each Rat-shilling is worth {{E}}0.10.

Any grind requires cashing out during the appropriate {{IL|1=The Rat-Season:|Appearance=Rat-Season}}. Take a look at the [[The Rat Market (Guide)|guide]] to plan out your grinds.

'''Items that sell higher at The Rat Market:'''

* {{E}}12.50 items for {{IL|Rat-Shilling|Appearance=}} 200 (170 in bulk), a mark-up of +60% (+36% in bulk). Selling items in bulk is only worth doing if your grind is higher than 3.75 EPA, since you’re saving 4 actions but losing {{e}}15 profit.
** {{IL|Uncanny Incunabulum}}
** {{IL|Storm-Threnody}}
** {{IL|Ratty Reliquary}}
** {{IL|Unlawful Device}}
* {{E}}62.50 items for {{IL|Rat-Shilling|Appearance=}} 850, a mark-up of +36%

** {{IL|Corresponding Sounder}}
** {{IL|Scrap of Ivory Organza}}
** {{IL|Cartographer's Hoard}}
** {{IL|Parabolan Parable}}

Once you have Rat-shillings, you can convert them to Echoes or [[Hinterland Scrip-Making|Hinterland Scrip]] by spending the shillings on items to resell at the Bazaar or in the Upper River.

'''Rat Market items that can be sold elsewhere:'''

* {{IL|Rat-Shilling|Appearance=}} 1 items ({{E}}0.10), always available
** {{IL|Inkling of Identity}}
** {{IL|Maniac's Prayer}}
** {{IL|Amanita Sherry}}
** {{IL|Map Scrap}}
** {{IL|Phosphorescent Scarab}}
* {{IL|Rat-Shilling|Appearance=}} 3125 items ({{E}}312.50), dependent on the {{IL|Direction of the Rat-Wind:|Appearance=Rat-Wind}} and {{IL|Phase of the Rat-Moon:|Appearance=Rat-Moon}}

The {{IL|Fabulous Diamond}} profit can be increased by {{e}}10 per diamond by [[Trade one Fabulous Diamond|trading it in The Hurlers]] for {{IL|Hinterland Scrip}}. This requires {{IL|Hurlers Commercial Development}} 2, and costs actions for the trade and for travelling to and from the Upper River. The action cost can be mitigated by saving diamonds to trade all in one trip.

*[[Trade one Fabulous Diamond|Trade]] one diamond for {{IL|Hinterland Scrip|Appearance=}} 625 (at value, as {{IL|Hinterland Scrip|Appearance=}} 1 is equal to {{e}}0.50), plus {{e}}5 in {{IL|Stolen Kiss|Appearance=Stolen Kisses}}.
*Spend the scrip on {{IL|1=Tinned Ham|2=5 x}} at {{IL|Hinterland Scrip|Appearance=}} 125 (equal to {{e}}62.50) each.
*Sell the ham to the Bazaar for {{e}}63.50 each, a profit of {{e}}1 per ham ({{e}}5 total per diamond).

*Favour grind gives you {{IL|Night-Whisper|12.2 x}} for 147.8/148.8 actions on average.

====Combination Tribute Grinds====
The above three methods all have disadvantages: Favours has the highest EPA but relies on card draws which limits realtime output, Orphans requires a large amount of starting cash, Mountain Sherds is fully grindable but has lower EPA, and both orphans and sherds have some inefficiency due to not getting 13 items on every trip. However, they can be combined in various ways to maintain full efficiency for each voyage while reducing some of the disadvantages of each individual tribute source, and to provide flexibility.

'''Requirements'''
*Same as above three
*[[The Minister of Culture]]
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
The below table assumes that all tribute is turned in for [[Night-Whisper|Night-Whispers]], which are then sold to the [[The Rat Market (Guide)|Rat Market]] during the weekends that it buys them. Actions are listed for twenty tribute cycle/trips, including zailing with a zub or yacht (14 actions); for the zee-clipper, subtract 1 action per trip, and for the tramp steamer, add 2. Favours are assumed to require 1 action each, and have no other cost; in reality, occasionally drawing [[A Visit]] (or, after finishing [[Associating with a Youthful Naturalist]], [[The Seekers of the Garden]]) will slightly reduce total actions for favours, but this will be balanced by the minor item/menace costs for many of them. Below table is for 20 cycles, with leftover tribute applied each cycle. If Favours are applied to top out at 260, 261, 262, 263--with the over-cap 1,2,3 tribute being discarded prior to the zail--the EpA increases somewhat.

'''Beneficial'''
* {{IL|a Preserver of London}}

By running expeditions to [[The Wellspring of Moulin]] with the Bandaged Navigator and the Miniature Major-General, you can gain {{IL|Flask of Waswood Wellspring Water|4 x}} in exchange for (on average) 21.96 actions {{IL|Piece of Rostygold|100 x}} and 10 {{H}}. These flasks can be converted to {{IL|Hiding Place of a Peculiar Item}} via [[Search Parabola for a Place in the Neath]], for an average of ~5.09 actions each with 280 {{IL|Shadowy}}, 12 {{IL|Glasswork}}. Gaining {{IL|Casing...}} from [[Search Parabola for a Place in the Neath]] (average 4.07 actions, plus 1 and {{IL|Drop of Prisoner's Honey|100 x}} to enter Parabola) and then doing heists of [[The shaded estate on Hemlock Row]] (average 10.11 actions with 11 {{IL|Glasswork}} and 10.04 with 12, ~0.001% chance of a heist ending in failurea and thus ~0.0005% chance of a heist resulting in jail time without a quick switch to an outfit with -2 {{IL|Suspicion}}, or some social actions followed by a -1 {{IL|Suspicion}} outfit) gives {{IL|Captivating Ballad|1 x}} and {{IL|Touching Love Story|16 x}}. Selling the {{IL|Captivating Ballad}} at the Rat Market gives a total profit of 511.58{{e}} per expedition<ref>Taking into account the [[A Lesser Find]] and {{IL|Altered, Somehow}} profits from the expedition</ref>, for an EPA of 4.92{{e}} with 10 {{IL|Glasswork}} in the heist outfit and marginally higher EPAs with higher {{IL|Glasswork}}.

===Hearts' Game Atlases (Rat Market)===
*Expected EPA: '''5.21-5.35'''
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
In the right Rat-Season, playing [[Hearts' Game (Guide)|Hearts' Game]] for 650 actions, taking the {{IL|Salt Steppe Atlas}} payout 26 times (26 actions) and using [[Money-Making/Lategame#Crackling trade|Crackling Trade]] (an additional 25 actions) makes 2125 E in Rat-Shillings plus 1625 E directly from selling Puzzling Maps. This is a total of 3750 E over 701 actions (zailing excluded), or up to '''5.35 EPA'''. If zailing is included, a single cycle is '''5.21 EPA''', though this improves with stockpiling, [[Piracy (Guide)|piracy]], and any other reasons to visit Khan's Heart. Spare Docks favours can also potentially be used to upconvert {{IL|Puzzling Map}}s for a hypothetical increase in EPA (maximum '''5.46'''), but the opportunity cost is probably greater than the benefit. Note that the significantly quicker and simpler Bone Market grind gets 5.31 EPA, so it's better unless you're already going to Khan's Heart.

==Reference==
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
The most profitable action in the game is [[A special delivery? (50 FATE)|A special delivery?]] although it is very expensive (in terms of actual money). There are more efficient ways to gain Echoes via Fate, see the section on Fate-locked grinds at the top of the page.
<!-- 
As a point of reference, grinding 11712.8e for an {{IL|Overgoat}} via the Special Delivery would take 37.48 actions and 1874 Fate, or $334.64 (even with the most efficient Fate purchase rate of 280 Fate per $50). Cider would take 512 actions and 25600 Fate, or $4571.43—you could achieve immortality in just a few days. Financially speaking, though, you'd be better off waiting for another [http://con-or-bust.org/archive/2016/05/fallen-london-firkin-of-hesperidean-cider/ Cider auction].
-->

These aren't grinds, classically, but are here to show you how many echoes you're earning in various repeatable activities:
*[[Calling in Favours (Guide)|Calling in Favours]] at the [[Call in favours at the Shuttered Palace|Shuttered Palace]], [[Call in favours in the Forgotten Quarter|Forgotten Quarter]], and [[Call in favours in the Wolfstack Docks|Wolfstack Docks]] gives 4.2 Echoes of items per favour, for an EPA of 2.1.
**If players [[Call in favours at the Empress' Court|call in their Society Favours at Court]], this is increased. After saving up 6x Society Favours, they may be exchanged in a total of 3 actions (Traveling to the Court and calling in Favours twice) to obtain a profit of 25 E, or 2.8 EPA. Calling in those 6 Favours normally would give 25.2 E for 6 actions, at the regular 2.2 EPA.
**[[Call in favours in the Flit|Calling in favours in the Flit]] to turn in Revolutionaries favours gives 12.6e for a total of four actions (3.15 EPA), [[Trade favours with urchins|25 scraps + Bundle of Oddities (max value 230)]] (12.17e in scraps + 1.64e in oddities = 13.81e/4a = 3.46 EPA) for Urchin favours or [[Trade favours with criminals|12e worth of items]] for four actions (3 EPA) for Criminal favours. Note that the common sources of Revolutionaries favours [[Offer a report from the Surface|give a point of Suspicion]], [[Disguise a Revolutionary-minded member|give a point of Suspicion and Scandal on failure]] or cost [[A personal approach|50p in Compromising Documents]].
*[[A furious and incoherent drunken rat]] gives 1.5 x [modified {{IL|Shadowy}}] pence per action in exchange for 6 CP of {{IL|Someone Is Coming}}, with a 1% rare success of [[Ratwork Watch|230e]]. With maximum {{IL|Shadowy}} (including a [[Cool as Ice|Mood]], a [[A Crooked Cross|Profession]], and [[Will you titillate listeners with the stories of your misdeeds?|Overcapping]]), the rat can give up to 4.7e per theft; including the rare success, this option gives a maximum of approximately 7 echoes per attempt on average, or 1.15 echoes per SiC CP. SiC may also be exchanged for [[A Gift from the Capering Relicker]]; note that [[Raw material]] gives you 22E for 10CP SiC, which is a better deal.
</div>

==Cards==
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
This section only lists cards with greater than 2.5 EPA.
*Drawing [[The Aftermath of the Great Sink of 1899]] twice, and then [[A Gift from the Capering Relicker]] (playing the [[Raw material|Bone Market branch]]), gives 26 {{e}} over 3 card draws (the last of which is guaranteed to occur immediately), which is '''8.67 EPA'''.
*[[The Calendrical Confusion of 1899]] has a variety of options with good EPA. Choosing [[Purchase wine at cut-rate prices]] can get anywhere from '''5.31 EPA''' to '''12.28 EPA''' at 230 base {{IL|Persuasive}} assuming you have the glim on hand. [[Check in with your Revolutionary contacts]] gets '''7 EPA''' at 230 base {{IL|Watchful}} and requires {{IL|Language of Laces}}. If you have completed a certain ending in Heart's Desire, [[Inquire as to the state of your arrangement]] gets '''4.78-5.76 EPA'''.
*For those with an {{IL|Inculcating Kraken}}, lodgings at the Spire-Emporium at the Bazaar, and high enough level of {{IL|A Player of Chess}}, [[Allow your Inculcating Kraken to engage in commerce|an option]] on the (Frequent!) Lofty Tower card gives on average '''8.5 EPA''' for those with 14 aPoC. Profitability drops with each missing level of aPoC, but even with aPoC 11 this action still yields '''5.1 EPA'''.
*[[Arbor, of the Roses]] by grinding massive amounts of {{IL|Attar}} and then cashing it all out via [[Gift your Attar in tribute to the Roseate Queen]] can get up to '''6.02 EPA''' if done in massive enough batches. More information can be found [[Arbor (Guide)#Making Money|here]].
*[[Discordant Ripples]] are 3 sets of highly profitable red-bordered cards, one of which can be added to your deck at a time once you have made sufficient progress at the Hurlers. Since these are red-bordered cards which autofire when clicked on, you do not need an action to play them (click on them when you have no actions left). Their payouts range from 4e to 12.5e, although the most valuable cards also give significant menaces.
*Favours ([[Favours: The Docks|the Docks]], [[Favours: Bohemians|Bohemians]], [[Favours: The Church|the Church]], [[Favours: Society|Society]], or [[Favours: Criminals|Criminals]]) to [[Tribute]]: see [[Money-Making#Favour_grind_(using_cards)]] ('''5.64 EPA''') and [[Money-Making#The Court of the Wakeful Eye (Rat Market)]] (around '''7 EPA''')
*[[A Visit]] has options which give out two Favours and rewards dependent on relevant base stats. At 200/230 gives 4/4.6e from Repentant Forger (Criminals, Bohemians) or Wry Functionary (Society, Great Game), 3/3.45e from Sardonic Music-Hall Singer (Bohemians, Society), 5/5.6e from Regretful Soldier (Docks, Constables). Note that the Forger and Music-Hall Singer will give you two Favours useable in the above grind.
*[[The Neath's Mysteries]] ([[A strange sort of prank]] is '''4 EPA''')
*[[Learn of the Overgoat|All fear the Overgoat!]] (gives 3.65 EPA at maximum base {{IL|Watchful}} (scales with base {{IL|Watchful}})
*[[The High Castle: What Occurs in a Rooftop Shack]] (3e). {{IL|Acquaintance: the Repentant Forger}} 9 is required to 100% the action; failing the check increases your Acquaintance.
*[[Engage in commerce|The Lofty Tower: the Potential of Premises at the Bazaar]] (2e + 4 scraps [3.7e incl. scraps])

Rare Frequency Cards:
*[[A disgraceful spectacle 2|A disgraceful spectacle]] (12.5e, sell the item to allow the card to appear again)
*[[A commotion above!]] (2.9/2.5/2.2e, only in your lodgings)
*[[The Bonfire of the Decencies]] (7.5e, but requires high bizarre, 6+ bizarre give greater than 5e)
Grinding (3200) [[Certifiable Scrap|Scraps]] to trade in with one of the Relickers for a Tier 8 (1562.5e) item is only efficient if an average rate of 3+ Scraps per action is maintained, giving roughly 1.5 EPA. Scraps are generally worth approximately .5e each.
</div>

===Dreaming Zee-Dreams===
*Requires a Ship
*Improved with access to {{IL|Khan's Heart}} and better ways of dealing with {{IL|Nightmares}}
*'''Up to 6.81 EPA''' over 11 cards
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
When {{IL|Zailing the Unterzee}}, you will eventually draw cards that allow you to experience Zee dreams.

{{IL|Southern Wind}} gives {{IL|Having Recurring Dreams: I Shot the Albatross}}, {{IL|Northern Wind}} gives {{IL|Having Recurring Dreams: Betwixt Us and the Sun}} and {{IL|Eastern Wind}} gives {{IL|Having Recurring Dreams: Upon a Painted Sea}}.

Each cycle of dreams takes 11 actions of dreaming and gives an {{IL|Oneiric Pearl}}.
Pearls can be exchanged for 62.5 {{e}} worth of items with an action, or sold in the Khanate and exchanged for a {{IL|Crackling Device}} that can be sold at the rat market for 85 {{e}} worth of items, at the cost of an action and 5 {{IL|Assortment of Khaganian Coinage}}. In the long run, this ends up giving 62.5 or 81.73 {{e}} per cycle in the long run.

Dreaming typically also gives nightmares.
* A cycle of Northern wind gives 19 CP
* A cycle of Southern wind gives 15 CP
* A cycle of Eastern wind gives no nightmares.

Assuming the winds are gained passively while travelling the zee, and that {{IL|Nightmares}} are cleared at 3 CP/action.

:The leftern value assumes throwing the pearls into the zee, while the rightern ones assumes exchanging the pearls for {{IL|Crackling Device}}s (requires access to {{IL|Khan's Heart}})
*{{IL|Northern Wind}}: 3.41 / 4.46 EPA
*{{IL|Southern Wind}}: 3.68 / 4.81 EPA
*{{IL|Eastern Wind}}: 5.21 / 6.81 EPA
</div>

==Weekly actions==

These are all actions that you can do once per week. Some depend on [[Time, the Healer]], other on living stories. These are especially great for casual players who do not have the time to spend 1008 actions per week. 

As you will only do these schemes once a week, they will take longer to enter your muscle memory than e.g. the newspaper grind. If you spend an hour reading up on bone market recipes while your actions are maxed out, this will not result in an optimal EPA. The low-hanging fruits are labeled easy and are recommended for everyone. 

The complex schemes are mostly interesting for people who already spend 900 actions per week, but want to gain the last possible bits of efficiency.

===[[A Professional Reward]] (easy)===
With a tier one profession, over '''8.125EPA'''. With a tier three profession, '''15EPA'''. 

Every four weeks, you can assemble four [[Professional Perk]]s to get one [[Trade Secret]], which [[...something else.|yields]] {{e}}125 for 11 actions, for a total of '''11.36EPA'''.
----
===[[The Rewards of Ambition]] (easy)===
This gives at least '''{{e}}62.5''' every four weeks after you have finished your ambition. 
*Owners of {{IL|A Vast Network of Connections Wherever the Bazaar's Influence can be Found|Appearance=A Vast Network of Connections}}, {{IL|A Winged and Taloned Steed Formerly Mr Veils|Appearance=A Winged and Taloned Steed}}, or {{IL|A Palatial Holiday Home in the Arctic Circle|Appearance=A Palatial Holiday Home}} receive items which can be sold at the Rat Market for '''{{e}}85''', an additional {{e}}22.5 at the cost of another action. 
**{{IL|A Vast Network of Connections Wherever the Bazaar's Influence can be Found|Appearance=A Vast Network of Connections}} additionally gives {{IL|Hinterland Scrip|Appearance=}}5, for a total of roughly '''{{e}}87.5'''.
*Owners of {{IL|A Kitten-Sized Diamond, Liberated from the Mountain|Appearance=A Kitten-Sized Diamond}} will receive a {{IL|Magnificent Diamond}} if they have an {{IL|Ostentatious Diamond}} (which is consumed), for a total of '''{{e}}74.5'''.
----

===[[Accept a gift from Balmoral's Castellan]] (easy)===
*{{e}}63.5 at '''18 EPA'''
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
'''Requirements'''
*{{IL|Balmoral's Castellan}}
All Castellans give you a gift worth {{e}}63.5 after Tinned Ham Arbitrage. If you fail the checks for the 2 actions traveling to/from Balmoral, '''15.875 EPA'''. Succeeding those is worth {{e}}5, raising EPA to '''18 EPA'''.
</div>

===[[Receive the latest 'reports' from your 'agent']] (easy)===
*{{e}}107.5 over 28 actions at '''3.83 EPA''' EPA Improved through [[Piracy (Guide)|Piracy]] to '''6.41-6.59''' EPA
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
Somewhat low yield compared to other weekly actions. Note that challenges in the Snares and the Salt Steppes can have very high requirements.

'''Requirements'''
*{{IL|An Agent of No Consequence}}, the current end of [[Khaganian Intrigue (Guide)]]
*Sufficient stats to 100% challenges in the Snares and the Salt Steppes. With piracy, 14+ {{IL|Zeefaring}} is needed for the snares to be worth considering. Having a {{IL|Zubmersibility|Appearance=Zubmersible}} or {{IL|Obstinate-class Cruiser}} is an advantage due to safety.
* A source of {{IL|Fistful of Surface Currency}} or {{IL|Assortment of Khaganian Coinage}}.

'''The Cycle'''
#Gain 510 x {{IL|Fistful of Surface Currency}} or 30 x {{IL|Assortment of Khaganian Coinage}} (worth ~15E)
#Travel to the Khanate from London via [[Trace a route through the Snares]] (at least 9 actions, approx. 10, 9 of which have Zee-EPA (Using 4EPA as Zee-EPA))
#[[Pay for cargo in Surface money]] or [[Pay for cargo in Khaganian money]] (3 actions)
#[[Enter Khan's Heart]]
#[[Receive the latest 'reports' from your 'agent']]
#Return to London via [[Trace a route through the Snares]] (at least 9 actions, approx. 10, 9 of which have Zee-EPA)
#[[Deliver the crate to the Widow]] 3 times

This results in {{e}}107.5 for 28 actions, for a total of '''3.83 EPA''' plus whatever you happen to pick up at zee. This assumes you're able to get either Surface Currency or Khaganian Coinage at sell value. This can be done by selling the occasional skeleton to [[The Trifling Diplomat]] while passing by or by selling skeletons to [[A Dreary Midnighter]] in London when he is the [[Occasional Buyer:|Occasional Buyer]]. Buying with {{IL|Fistful of Surface Currency}} is slightly preferable, since {{IL|Assortment of Khaganian Coinage}} can be used to buy Crackling Device and cashed out in the Rat-Market during its appropriate seasons. In fact, additional profit can be made by [[Assembling_a_Skeleton_(Guide)/Recipes#Khaganian_Hydra_Arbitrage|assembling a skeleton to sell to the Diplomat for Coinage]] for this purpose on your way to pick up the report.

Zailing around through {{IL|Shepherd's Wash}} and {{IL|The Sea of Voices}} with a Clipper would make the challenges more manageable, but would add 3 zailing actions both ways for a total of 12 one-way. Assuming a Zee-EPA of 3.5, this gives an EPA of '''5.76'''. Using a zub would give around '''5.57''', though this could be increased by taking the route through the Snares on the way back. If you're doing other things on your journey and can discount parts of the trip, this will increase further. Discounting the distance from London to Shepherd's Wash both ways (e.g. when doing tribute runs) would give the EPAs '''6.29''' and '''6.09''' respectively.

===Board Meeting Dividends (moderate)===
*Up to {{e}}156.08 for 19 actions, for a total of '''8.21 EPA'''
*Several requirements for maximum efficiency
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
If you have a Pro-Labour Railway Charter, you can use Furnace or Cornelius in lieu of The Vicountess's {{IL|Persuasive}} 200 check. However, this will lower the final payout by {{e}}10 and lower EPA by 0.52.

'''The cycle'''
#Boomerang the Tentacled Entrepreneur
##[[Invite the Tentacled Entrepreneur to the Board]]
##[[Vote the Tentacled Entrepreneur off the Board]]
##5 actions to convince your board members and declare victory
#Voting for dividends 2 times
##[[Vote a dividend to the shareholders]]
##5 actions to convince your board members and declare victory
In the absolute worst case scenario (Ealing, no Luxuries, Pro-Labour Charter), this yields {{e}}100.08 for 19 actions (after Tinned Ham Arbitrage), a total of '''5.26 EPA'''. Note that using {{IL|Help from the Board Secretary}} will allow you to repeat this but lowers efficiency slightly to '''5.13 EPA'''. With the Recommended qualities, this yields {{e}}156.08 for 19 actions, for a total of '''8.21 EPA'''.

===Board Meeting Charity (complex)===
*2-3x {{IL|Bottle of Fourth City Airag: Year of the Tortoise}} per Board Meeting.
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
'''Requirements'''
*{{IL|Board Member: Sinning Jenny}}
*{{IL|Board Member: the Gracious Widow}}
*{{IL|Involved in a Railway Venture}} 60 (Have build the station at {{IL|Jericho Locks}})
Additionally at the start of the Board Meeting have:

#When [[Rising Reports of Banditry]] autofires, select [[Ticket sales are going down]].
#[[Invite the Gracious Widow to the Board]]
:*If debt remains, get rid of it (via e.g. [[Raise funds for the railway]], -12.5{{e}})

In total, you have six items on the board agenda, each of which should take six actions. Combined with the rest of the actions this should take in total 42.66 actions. 

Your net gain will be 196.66 Echoes, on average for '''4.6EPA'''. If the {{IL|Bottle of Fourth City Airag: Year of the Tortoise}} are sold at the Khaganian Markets for {{IL|Crackling Device}}s according to [[Money-Making/Lategame#Crackling Trade]], the net gain increases to 254.35{{e}} at the cost of 2.88 actions, increasing to '''5.6EPA'''. 
</div>

----

===Board Meeting Assistance to Parabolan War (moderate-complex)===
*Up to 380 {{e}} at up to '''9.51 EPA''' over 5 Board Meetings
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
If you're engaged in a Parabolan War campaign, you can use your weekly board meeting to fully advance one stage in the war. It also causes 8 x {{IL|Ravages of Parabolan Warfare}}, but the weekly ''Time, the Healer'' is enough to remove those.

The following is slow: advancing one stage of the war per week, for a cash-out only after 5 weeks. So you'll only spend on average 8 actions per week, but those few actions end up being very profitable.

'''Requirements'''
*{{IL|Board Member: The Viscountess of the Viric Jungle}}
* 3 other Board Members who are OK with Parabolan Warfare (e.g. The Drummer, September, or the Gracious Widow)

'''The cycle'''

Assume we start already at the end of one of the stages of the Cats campaign (i.e. {{IL|Advance!}} is already 24), with no Ravages:
#Move into Parabola. Costs 100 x {{IL|Drop of Prisoner's Honey}} (only 50 for Silverers)
#Progress your campaign to the next stage.
##If you've just completed stage 4 (Along the Smoking Shore), ensure to [[Encourage the Prince to reject the King's offer]].
##If you've just completed stage 5, collect your reward and start a new Cats campaign (no general).
#Return to London (0 actions)
#Assemble a board meeting:
##[[Propose you deploy your train in the Parabolan War on behalf of Cats]]
##The Viscountess automatically agrees.
##4 extra actions to convince the other board members and declare victory.
#Wait for ''Time, The Healer'' to remove Ravages of the war.

This involves 5 board meetings (costing just 5 actions each), 5 entries into Parabola (costing 500 x Drops of Honey, which can be bought from the Bazaar for 20 Echoes), and 10 extra actions in Parabola to start a campaign, progress between the stages, and to collect the reward. The reward is a {{IL|Parabolan Parable}}, worth 312.5 Echoes. So we have (312.5 - 20) Echoes / 40 Actions = '''7.3125''' EPA (or '''7.5625''' for Silverers).

'''The Rat Market'''

If you wait for {{IL|The Rat-Season:}} Kifer-Caitiff, Skitter-Scatter or Dimmest-Dark, you can [[Sell a Parabolan Parable for 4000 Rat-Shillings]] (at the cost of an additional action). This means: (400 - 20 ) Echoes / 41 Actions = '''9.268 EPA''' (or '''9.512''' for Silverers).

===[[The Waters of the Wellspring]] (complex)===
Somewhere between '''4.55''' and '''4.8EPA''', but only for {{IL|Crooked-Cross}}es.
<div class="mw-collapsible mw-collapsed mw-collapsible-content">

'''Requirements'''
*One of
**{{IL|Kataleptic Toxicology}} 8 ''and'' {{IL|Transfixing Squirrel}}

'''The basic cycle'''
#Travel to Moulin
#*[[Pay off your Assistants]] with Hinterland Scrip if necessary
#[[Recruit a Miniature Major-General]]
#[[Recruit a Bandaged Navigator]]
#[[Set off]]
#Move away from Moulin and deeper into the Waste (5 actions)
#[[The Wellspring, at Last]]
#[[Bathe in the waters]]
#[[Collect some Wellspring water]]
#[[Cross the Threshold]]
#[[Look for the fingerking]]
*At some point, [[Sell it to a honey-den|Sell your Wellspring water to a honey-den]] 4 times

You should always be able to make it to the Wellspring without incurring menaces. The basic cycle yields {{e}}48.20 and {{IL|Memory of a Much Lesser Self|1 x}} for 19 actions, for a floor of '''2.53EPA'''. This is much lower yield than other weekly actions, but playing [[A Lesser Find]] and [[Something Nacreous]] will raise EPA to something around '''2.8EPA'''.

If you keep track of when [[Viric Fades]] is going to trigger (by e.g. adding [[Bathe in the waters]] to your list of plans and adding a note stating the last time you did it), then you can arrive at the Wellspring shortly before [[Viric Fades]], [[Collect some Wellspring water]], and wait for [[Viric Fades]] so you can [[Bathe in the waters]] as normal. This allows you to gain an extra four flasks of Wellspring water, gaining {{e}}50 at the cost of 5 additional actions, raising the basic cycle to '''4.09EPA'''.

'''Recommended'''
#<li value="7">Instead of [[Bathe in the waters]], [[Dip your Cross in the Waters]]</li>
Eventually
*[[Lend inventively]] to exchange {{IL|Revisionist Historical Narrative|1 x}} for {{h}}
*[[Noisily subvert the entire process]] to exchange {{IL|Verse of Counter-Creed|1 x}} for {{h}}

This cycle yields after THA {{e}}95.63 for 21 actions, for a floor of '''4.55EPA'''. Again, the true EPA will be slightly higher at around '''4.8EPA'''.

----

===The Heists of the Wellspring (complex)===
About 6.0 EPA, more for some professions. 
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
'''Requirements'''
* A willingness to risk [[New Newgate Prison - again!|imprisonment]]
*An outfit that grants 12 [[Monstrous Anatomy]]
'''Recommended''' 
*An [[Alliance with the Big Rat]]
*Being either a [[Silverer]] or a [[Crooked-Cross]]
*An outfit that gets you to ''both'' 12 [[Glasswork]] and 12 [[Monstrous Anatomy]] (Monstrous Anatomy is more important)
*Max level [[Parabolan Defences]] or a willingness to use social actions.
There are two basic components to this grind: Getting [[Flask of Waswood Wellspring Water|Flasks of Waswood Wellspring Water]] and turning them into [[Hiding Place of a Peculiar Item|Hiding Places of Peculiar Items]], then stealing those items. 

'''Step one: The Expedition'''

The basic cycle for a Wellspring expedition is as follows: 
#Travel to Moulin
#*[[Pay off your Assistants]] with Hinterland Scrip if necessary
#[[Recruit a Miniature Major-General]]
#[[Recruit a Bandaged Navigator]]
#[[Set off]]
#Move away from Moulin and deeper into the Waste (5 actions)
#[[The Wellspring, at Last]]
#[[Bathe in the waters]]
#[[Collect some Wellspring water]]
#[[Cross the Threshold]]
#[[Look for the fingerking]]
Once there, mark the time you made the '[[Bathe in the waters|Bathe in the Waters]]' action. On the following week, arrive just before this time elapses and collect 4 [[Flask of Waswood Wellspring Water|Flasks of Waswood Wellspring Water.]] Then when Viric Fades triggers, you'll be able to collect 4 more flasks in a single visit. 

As soon as you are in Parabola, turn all you flasks into [[Hiding Place of a Peculiar Item|Hiding Places of Peculiar Items]] via [[Search Parabola for a Place in the Neath]], and perform [[Find the weakness in an opponent's defences]] once. 

When you leave Parabola, you will be afflicted with [[That Which was Taken (Fallen London)|That Which Was Taken]]. Choose the nightmares option and lower it with [[Hide in your Base-Camp]], or choose either wounds or nightmares and lower the menace with social actions. 

'''Step two: The Heist'''

The goal is to begin the heist with 2 pieces of [[Inside Information]] using as few actions as possible. To do that you need [[Casing (Guide)|Casing...]] and the best ways to get that are: 

*[[Purchase some assistance with Casing...|Purchase some assistance with casing...]]
*[[Find the weakness in an opponent's defences]]

Including transportation costs, [[Purchase some assistance with Casing...|Purchase some assistance with casing...]] is the superior choice, even for Silverers. Ignoring them, [[Find the weakness in an opponent's defences]] is slightly better. So get your Casing... from Parabola if you're there already or don't have access to the Big Rat, get it from the Big Rat otherwise. 

Once you have your Casing... go ahead and start the heist from [[The shaded estate on Hemlock Row]], buy 2 pieces of inside information, and put on your outfit that gives both a [[Monstrous Anatomy]] and a [[Glasswork]] of 12. Note that passing the [[Monstrous Anatomy]] check is more important, so if getting it up to 12 requires replacing some [[Glasswork]] items you should still do it. 

Once you reach [[A Prize Achieved!|A Prize Achieved]], select the Captivating Ballad and sell it at the Rat Market. Repeat the above until you are out of [[Hiding Place of a Peculiar Item|Hiding Places]]. 

'''Professional Improvements'''

[[Monster-Hunter|Monster-Hunters]] will find it easier to obtain the required outfit. 

[[Silverer|Silverers]] will find it easier to obtain the desired outfit and take less damage from [[The Mirror's Hunger]]. This raises EPA to about 6.1. They also pay less to enter Parabola, useful for characters without access to the Big Rat. 

[[Crooked-Cross|Crooked-Crosses]] may [[Dip your Cross in the Waters|Dip their Cross in the Waters]] for additional resources. With [[Jericho Library]] 2 and a [[A Submerged Rector|Submerged Rector]] this brings EPA to about 6.3. 

'''Folly'''

Using [[Purchase some assistance with Casing...|Purchase some assistance with casing...]] only twice and purchasing no [[Inside Information]] will net about 7 EPA. While this looks tempting, performing the most difficult heist 8 times a week with no Inside Information will certainly land you in prison eventually. But perhaps you really are the best thief in the Neath.

===Using up Bone Market Exhaustion (easy - complex)===
*Roughly 200 {{e}} per week at various speeds.
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
See [[Assembling a Skeleton (Guide)]]. Your [[Bone Market Exhaustion]] drops by four every week, which corresponds to 200E worth of bonus items. 

Playing the bone market is rather intricate. Also note that exhaustion can lock you out of profitable non-exhausting use of the bone market for weeks (or years).

Using up Exhaustion is hard in the mid-game, but still profitable. Exhaustion in itself is around 200 {{e}} per week. If you have {{IL|A Custom-Engraved Skull}} from {{FontRose}}, you can use those, leading to a net gain of 160 {{e}} for 2 skulls. The exception to the rule is when the Phantasist is around - then you'll be able to spend all your exhaustion through other means.

If you're a lategame player, you could use the least number of actions to use up {{IL|Bone Market Exhaustion}} as efficiently as possible, see [[Assembling a Skeleton (Guide)/Recipes#Amalgamy Bomb]].

===The Nadir (complex)===
Highly random, but in the long-term, '''8.13EPA'''.
<div class="mw-collapsible mw-collapsed mw-collapsible-content">
'''Requirements'''
*{{IL|Route: The Cave of the Nadir}}
The Nadir can be entered once a week without spending Fate. Players are [[Drowning in violet|forcibly ejected]] from the cave when reaching {{IL|Irrigo|10 x}} whereupon it is not possible to return until the next visit from [[Time, the Healer]] ([[Irrigo, begone (50 FATE)|unless they wish to pay 50 Fate]]). Optimal play yields approximately '''8.13EPA''' — see [[Cave of the Nadir (Guide)#Analysis]] for details

== Intermittent Actions ==
{{WIP|User=Kislev|Reason=needs elaboration on world events}}
These grinds are profitable but operate on a much longer timescale, from weeks to even years. This includes grinds tied to seasonal events, World Qualities, or that otherwise only open up after multiple time-limited events.

=== Discordant Soul Redemption (complex) ===
{{Spoiler|Spoiler Type=Discordance|overlay=no}}
Difficult requirements for maximum efficiency; between '''6.63-11.40 EPA''', not counting Discordant Ripples and optional bones. Between the extremely steep requirements and the long time scale, this is only of interest to those grinding highly expensive items such as [[Treasures of the Neath (Guide)|Hellworms, Hesperidean Cider, the Heptagoat, and A Woeseller]]. 

Discussion for this grind is hosted separately at [[Deeper Discordant Studies (Guide)/Completed]], to avoid spoilers.

=== Living World Events ===
==== Zee Monster Hunts ====
===== Angler Crabs =====

===== Ravenous Lifeberg =====

===== Midnight Whale =====

==== A War in Spite ====

==== The Great Crate Commotion ====

=== Seasonal Grinds ===
==== {{FontRose}} ====
Currently, there are no known money grinds only available during the Feast of the Rose.

==== {{FontWhitsun}} ====
===== De Gustibus (easy) =====
Around '''2.5-5.5 epa''', depending on items offered.
<div class="mw-collapsible mw-collapsed mw-collapsible content>
For an endgame player, most of the options for redemption at De Gustibus are fairly disappointing. The most profitable is to grab a {{IL|Tiny Cave Fish}} at {{FontHallowmas}} and hold onto it for a few months, which gives a net of {{e}}11 for two actions. Other options, including {{IL|A Recipe for Zzoup}}, are not worth playing.

Gaining {{IL|De Gustibus: Eggxhaustion}} is only about 2.5e as well; fairly good for a player in the early or midgame, but not worth it for an endgame player unless you really care about the {{IL|Making Waves}}.
</div>

===== Hellworm Cheese (easy, but exclusive) =====
Annual benefit of {{e}}''62.5-125'' for Hellworm owners.
<div class="mw-collapsible mw-collapsed mw-collapsible content>
If you have {{IL|Your Very Own Miniature Hellworm}}, saddled or not, one of the items you can produce from milking it is, surprisingly enough, {{IL|Hellworm Milk}}. This can be given to the Questionable Cheesemonger at Whitsun and, one entire year later, be turned into {{IL|Ripened Wheel of Hellworm Cheese}}.

Hellworm cheese is worth {{e}}62.5 at the Bazaar, but one and only one time, you may become {{IL|A Purveyor of Cruel and Unusual Cheeses}}, worth {{e}}312.5, or {{e}}357.5 with use of the Rat Market.
</div>

==== {{FontSummer}} ====
There's no way of knowing what Estival will be like in any given year, but it's usually balanced so that participating in the event is more profitable than normal gameplay. 

==== {{FontFruits}} ====
TBD for new Fruits.

==== {{FontHallowmas}} ====
===== Menace Profit (easy) =====
Indirectly increases profit of other grinds.
<div class="mw-collapsible mw-collapsed mw-collapsible content>
The most interesting thing about Hallowmas from a money-making perspective is that it makes Menaces free, and in fact slightly profitable with {{IL|Spirit of Hallowmas}} (though Spirit is not that profitable to grind directly). There aren't any grinds exclusive to Hallowmas, but it's encouraged to try riskier and more menacing actions here. Grinds that involve menaces directly as well, such as dealing with {{IL|The Mirror's Hunger}} from Wellspring visits, become more profitable at Hallowmas.

As noted above as well, you may want to pick up a {{IL|Tiny Cave Fish}} for selling to De Gustibus.
</div>
==== {{FontChristmas}} ====
=====Christmas Cards (easy, social)=====
Efficient source of Second Chances for various uses.
<div class="mw-collapsible mw-collapsed mw-collapsible content>
As part of the Christmas cheer, you can send and recieve {{IL|Potential Christmas Card}}s. In addition to being very efficient menace cleanses, these lovely cards are also one of the most efficient sources of Second Chances in the game, and they're uncapped at that! Coordinate with friends and try to make sure you don't waste any of them, and if you're looking for particular Second Chances, be sure to try shuffling the Airs of London, which is most profitably done by [[Brawling with Dockers (Guide)|Brawling]].

Stockpiles of Second Chances from Christmas can be useful for several things when it comes to money-making. All of the types but especially {{IL|Hard-Earned Lesson}}s can be useful when Zailing in dangerous regions like {{IL|The Snares}} and {{IL|The Pillared Sea}}. Smart use of Second Chances can be the difference between reaching port with all your Plunder intact or paying an unexpected visit to the Boatman. The card {{IL|An Unlikely Garden}} in the {{IL|Cave of the Nadir}} also benefits from a stockpile of {{IL|Confident Smile}}s.

Second Chances can also be directly utilized on {{IL|The End of Battles}} in the {{IL|Cave of the Nadir}}: exchanging {{IL|Sudden Insight|3 x}} for {{IL|Bottle of Fourth City Airag: Year of the Tortoise}} is probably the most profitable overall when arbitraged in the Khanate for {{IL|Crackling Device}}, but all of the options are worth at least {{e}}62.5. Note you need {{IL|Favours: Tomb-Colonies}} in order to [[Trade your Collection of Curiosities for five Puzzling Maps|profitably]] redeem {{IL|Collection of Curiosities}}.

==Extras & Historical==
[[Money-Making/Extras]] show simple end-game grinds - grinds that aren't as good as the ones listed here, but only uses a single click. The page also lists ways to spend Fate in order to grind money.

Some grinds have been nerfed so much are simply become unavailable that they are not mentioned on this page anymore. These grinds are preserved [[Money-Making/Historical|here]] for historical interest but are no longer relevant for Money-Making.
