Secrets of the Witchkind
This d20 System supplement introduces the Witchkind, a player character race whose culture and abilities are deeply connected to magic. It includes character creation rules, details on their distinctive spellcasting methods, 17 feats, and six talent trees that expand their magical capabilities. Designed for d20 Modern, the material can be adapted to other d20 settings and supports a looser style of spellcasting inspired by fantasy fiction and television.
