Follower traits

Each of your Followers can have several distinguishing traits. Traits can be positive or negative. Permanent ones can be given to followers through the use of Doctrines.

Spawning Specifics

Unique Followers have their own pre-determined traits that may or may not follow the method below, possibly leading to over 3 traits.

Generic Followers do not have preset traits and will follow the following method to generate 1-3 traits:

The first trait will roll a max of 100 times for a random Starting Trait that does NOT match a Cult Trait, or else it gives a "None" trait. The Fear of Death trait and Against Sacrifice trait are unavailable if another Follower already has it.
The second trait repeats step 1, but does NOT add the trait IF: (1) it matches the first trait OR (2) it matches an Exclusive Trait.
The third trait rolls a random number between 0 and 1. If it is less than or equal to 0.2, it will repeat step 1 but for Rare Traits and without the Fear of Death/Against Sacrifice check (since they are not part of the Rare Trait list).
If step 3 fails, it rolls again. If it is less than or equal to 0.4, then it repeats step 2.

This leads to an average of 1-3 total traits. It is technically possible to get 0 traits but the probability of doing so is so low as to be effectively impossible. The best chance would be to get the Industrious Cult Trait from Work & Worship and Materialistic trait from the Possessions Cult Trait along with having Followers with the Fear of Death and/or Against Sacrifice trait. This leads to a 2/11 chance of getting a cult trait, leading to a: (2/11)^2(100) * 0.8 * 0.6 = 4.0616578729180591e-147% chance (This calculation is probably wrong since I don't see the Industrious Trait in the game files for Starting Traits).
