How traits and ancillaries work
A trait collects points from triggers (events like "won a battle" or "ended the turn in a city with a church"). Each level has a points threshold: reach it and the character gets that level and its effects. Many triggers only fire with some probability, and some take points away. Ancillaries are simpler: a trigger either hands one over or it doesn't, and a character can carry at most 8.
