Changing Ways (W20)
This roleplaying sourcebook explores the Garou, supernatural warriors who are part human, part wolf, and part spirit, and their struggle to defend Gaia. It examines how transformation affects the body and mind, including shifting senses, instincts, healing, and the spirit-given Gifts and Rites that empower them. The book details the experiences of lupus and metis characters, along with ways packs can be organized as groups of warriors. It also provides pack frameworks, new tactics, and systems for developing the pack as part of play.
