Personality

Personalities are special qualities possessed by some heroes that can provide meaningful advantages or disadvantages in either the strategy or tactical portion of the game. They are similar to traits in that regard, but personalities are typically acquired through seeding and training, whereas traits are usually acquired at birth via a genetic system.

Singularity and duality personalities
"Singularity" personalities are not paired with any opposite personality. "Duality" personalities, however, have an opposite. It isn't possible for heroes to have both personalities in a duality pair.

Common and unique traits
Common personalities have no special requirements to appear on heroes, and as such, they can randomly appear on heroes not trained in keeps. Unique personalities, on the other hand, must be acquired through special means. Currently, the available unique personalities are acquired through certain outcomes of some random events.

Minimum and maximum age
Some personalities do not activate until the hero reaches a certain age. Note that an inactive personality is hidden and will not be revealed until the hero reaches the minimum age. The hero may still train others in the personality, however. Thus far, there are no personalities with a maximum age, though such functionality is supported and may be seen in the future.

Acquiring desired and eliminating undesired personalities
A hero's personality is influenced by the regent and partner at the keep where he or she trains and by all standards, all of whom count as the hero's trainers. Each trainer has an equal influence on a trainee's personality every day. The total amount of influence on any given personality does not change with the number of trainers; instead, each simply exerts less individual influence. This means for the highest chance of passing on a particular personality, it is best to try to make sure as many trainers as possible.

Personalities in a duality pair are more complicated as influence towards one counteracts influence toward the other. If two of a hero's trainers have opposite personalities and the other trainers have neither, the influence of each is completely cancelled out.

Unless the hero has no progress toward any given personality upon coming of age, which should be rare as some random progress is seeded at birth, one to three personalities will be randomly selected with the odds weighted toward the most trained personalities.
