Evolution
From The Unofficial POWDER Wiki
When monsters are tamed, and especially when created as familiars, they have the potential to gain levels by killing monsters, just as the avatar does. The avatar can also give them more experience directly, with the Transfer Knowledge spell.
Certain monsters have the potential to "evolve" directly into more powerful forms as they gain levels. Some monsters have only one "advanced form" available, while others, like the familiar Bat, can go through two or more extra forms in sequence.
When a creature evolves, its hit points and maximum mana get rerolled based on their new monster definition. This will erase both the effects of system shock, and any gains from drinking potions or eating corpses.
