Leader Traits

Each personality is reflected in their permanent traits. These may provide bonuses or maluses and/or affect the leader's actions. Traits may be gained but never removed.

Acquired traits are added randomly as the game progresses. There does not seem to be anyway to affect when they gained, and whether they are positive or negative does not appear to be related to their current opinion level. You will receive a notification whenever a new one is acquired.

Inherent traits are present when a leader is first hired and cannot be gained by any other means. The trait is rare but particularly powerful.
