# Cover Identities (Guide)

 End-Game Content

## Mechanics

### Cabinet Noir

In order to construct a Cover Identity, you need at least Cabinet Noir. Higher values of Cabinet Noir enable more advanced Identities with more available Cover Identity Qualities. The Cabinet Noir can be built and upgraded in Offices of the Tracklayer's Union: Balmoral Branch for the usual scaling cost of (50 x ( Balmoral Development + 1)) x Hinterland Scrip in addition to the other listed requirements.

### Constructing an Identity

#### Starting a New Identity

A new Cover Identity always starts with Cover Identity: Elaboration 1. With Cabinet Noir 4 and either Favours to spend, Ambition items to show, or Whitsun beasties to enclue, it is possible to also set Cover Identity: Ties when creating a new Cover Identity. It is not possible to later add or change Cover Identity: Ties until you lose your current Cover Identity and start a new one.

## Strategy

Assuming all checks are 100%, the baseline cost of a constructing a Cover Identity is ( Cover Identity: Elaboration + Cover Identity: Credentials + Cover Identity: Nuance + Cover Identity: Witnesses) actions. You may also have a cost of 1 Favour for adding Cover Identity: Ties. The cost in both items and actions of Cover Identity: Backstory depends on the options used to raise it, but can also be fairly approximated as 1 action per Backstory with some exceptions.

From this, we can determine that Provide an Urchin with evidence that she's a long lost heir, Sell an undercover identity to a constable, Sell a socially plausible cover identity to a Devil each cost 5 actions (not including travel) + 1 Favour to receive 2 Favours. We can also approximate that Put up a statue in honour of your Cover Identity (which is to say, yourself) costs 14 actions + 1 Favour.

Involve the Clay Highwayman's gang in industrial steel robbery (Non-Marauder) costs 32 actions + 1 Favour to receive 10-11 Railway Steel. In order to get 10 railway steel from other sources, it takes 2 actions, 230 BSI and 2 Justificande coins. Assuming 2 actions for the coins, and 1 action for the favour, one would have to get more than roughly 7.9 or 8.7 BSI/action to make it more efficiently through other sources. This is in line with the best sources of Steel.

Selling a very advanced identity to Devils or to to Spies costs around 530 actions to receive an Intercepted Document that results in a Reported Location of a One-Time Prince of Hell or Rumourmonger's Network, respectively.

We can also approximate that Fence this identity is upper-bounded at 2.50 EPA. Each point of Cover Identity: Elaboration, Cover Identity: Credentials, Cover Identity: Nuance, or Cover Identity: Witnesses adds one 2.50 E item to the reward and each 5 points of Cover Identity: Backstory adds one 12.50 E item. Spending a Favour to add Cover Identity: Ties when starting the identity does not increase the reward at all, but merely changes which 2.50 E items you receive. That said, while it does not compare favorably to other options as an Echo grind, this is a good source for some of the possible rewards.

### Elaboration

The scaling difficulty check for increasing Elaboration means even top-level characters will not be able to guarantee success when building an Identity that require high level of Elaboration. The challenge to add a 10th point of Elaboration has a difficulty of 240, which would take Shadowy 400 to guarantee success. A realistic value of Shadowy 300 gives only a 75% chance of success. On average it will take ${\displaystyle 1/0.75=1.33}$ attempts to achieve success.

The table below summarizes the scaling challenge, success chance, and cumulative action cost for a character with Shadowy 300. The scaling is not exactly proportional, but is somewhat close. A character with 280 Shadowy would take 11.78 actions on average to reach Elaboration 10, while a character with 320 Shadowy would need 10.74 actions on average.

Elaboration Challenge Success % Attempts Needed Cumulative Actions
1 150 100% 1 1
2 160 100% 1 2
3 170 100% 1 3
4 180 100% 1 4
5 190 95% 1.05 5.05
6 200 90% 1.11 6.16
7 210 86% 1.16 7.32
8 220 82% 1.22 8.54
9 230 78% 1.28 9.82
10 250 75% 1.33 11.16

### Backstory

There are several items which can be spent to gain backstory.

Well-Placed Pawn: It's hard to get these reliably.

Vienna Opening: Overall, this ends up at x ~1 per action.
