Fantasci20: Creature Creator

A creature-creation guide for fantasy roleplaying games. Monsters use the same six classes, skills, and feats as other characters, while differing mainly in their lack of backgrounds, occupations, hobbies, and Reputation. The guide provides new feats and guidelines for building a wide range of monsters and creatures, with intelligent creatures able to receive these character elements at the game master's discretion.
