Temperament

Each hero has a temperament which modifies the hero, and remains part of them if they are captured and converted into a monster.

Your starting acolyte always begins with their own temperament, which can be upgraded at the Dark Gods' Spear using Progenitor Blood. Once upgraded to the Awakening level they will keep their own temperament effect when transferred a hero's temperament. When a prisoner is converted into a monster they keep the temperament of the hero.

Body Swap, once acquired, allows you to apply a new prisoners temperament to one of your existing monsters.
