Casing (Guide)

Spoiler warning!
This page contains details about Fallen London Actions.

Casing... is used for four endeavours:

For details on the first two villainies check the corresponding quality pages. (Note that CPs and levels of Casing are interchangeable between all sources and crimes, i.e. you do not necessarily have to steal paintings to do the Topsy King one)

Gaining Casing...[edit]

Preparing for a Big Score[edit]

Preparing for a Big Score in The Flit unlocks at Shadowy 73. Here are the options and possible outcomes (disregarding skill challenge based CPs to Shadowy).

Steal paintings[edit]

If you instead agree to steal paintings for the Topsy King - which is not mutually exclusive with planning a heist, so you can have both selected at the same time - you can steal a painting from a struggling artist (costs 10 Greyfields 1879, grants +2 Casing on success or +1 Suspicion on failure) or a noted gallery (grants +3 Casing on success or +1 Suspicion on failure). Each of these takes 1 action point, so this can be used to grind Shadowy slightly faster.

Big Rat[edit]

Furthermore; if you made a deal with the Big Rat you can Purchase some assistance with Casing... from the Alliance with the Big Rat storylet available at your lodgings. At 9 CP per Action point, this is the most action-efficient method, but it is of course a bit costly.

Parabola[edit]

In addition to the above, there is a late game option to acquire casing in Parabola by Finding the weakness in an opponent's defences, however this requires Shadowy Gains 6. Furthermore, this involves a Shadowy challenge with high difficulty; spending an Action point to reduce the difficulty may be needed to make this method more reliable, but this reduces the CP per Action from slightly over 9 to 7.

Helicon House[edit]

Late-game players can also gain Casing... at Helicon House. See the Tables of Progress Qualities in the house guide.

Using Casing...[edit]

Sell Information[edit]

You can Sell information to these three factions (unlocked with Casing... 3):

Thefts of Particular Character[edit]

You can do Thefts of Particular Character once you reach Casing 10 to gain different items (requires Shadowy 73). All options will gain 12.50 Echoes worth of items after a Shadowy 120 challenge costing you 32 CP of Casing if successful. Failing will give the same amount of items but deduct 51 CP Casing. The options are:

Embark on a Heist[edit]

You can choose to Embark on a Heist. Check the On a Heist (Guide) page for a guide and advice.

Various thefts in the Flit[edit]

You can do larger crimes at various difficulties, all of them resetting your Casing if successful:

Suggested level and expected actions per theft assume that you can gain Casing... at 3 CP/action and reduce suspicion at 4 cp/action usually, or 2 cp/action while in prison. Bear in mind there may be other consequences as well. The numbers are not completely accurate due to rounding, in reality they will usually be higher.

  1. Assumes Casing... gained at +3 CP/action, and all attempts at level 5 (30% chance of failure). Expected actions is 6 + (0.3^1 * 3) + (0.3^2 * 3) + (0.3^3 * 2) + ... —note that the number of additional actions for each failure depends on whether the sum of all previous failure penalties is divisible by 3.
  2. Hard to measure due to prison mechanics
  3. This will increase Nightmares from 0 to 8 and drive you mad unless you wear Nightmare-reducing gear

Highway Robbery[edit]

If you've made it at least partially through the Clay Highwayman's story, you'll have access to Assorted Larcenies at his camp in Balmoral. These crimes can be accessed through the card deck there (it's infinite draw), do not have associated challenges, and have overall high EPA.

The EPAs for some of the options are hard to calculate. For example, Consignment of Scintillack Snuff cannot be sold directly and must be converted either to Hinterland Scrip via Engage in a bit of smuggling or Preserved Surface Blooms via Offer a well-packed keg of scintillack snuff. The calculated EPAs below generally assume that the items are directly sold, or sold as directly as possible. In cases where this is not possible, EPAs are approximate.

Arguably, larcenies with 8 casing in Balmoral are the most rewarding from an EPA perspective as they pay in scrip, but neither option is particularly outstanding, unless you need some specific resources.

Grand Larcenies[edit]

By combining Casing... 10 with a Cover Identity, several more advanced larcenies can also be done.

The following table from the Cover Identity guide shows the different items that can be stolen. It's hard to measure an EPA value for these options, but if one assumes 20 actions per cover identity, 10 actions for casing and 200E in cover identity supplies it provides around 3.75 EPA. That's very optimistic assumptions, however. Based on this, these rewards are good if you need them, but not something one would usually do for echoes.
