From the campaign:
Strange Brew: The Ultimate Witch & Warlock is the book that will bring all of these products together in one massive volume. This book will combine the efforts of members of the original team that worked on The Way of the Witch and the original author of Liber Mysterium: the Book of Witches and Warlocks.
This book will contain everything you need to play any sort of witch, warlock, or witchlike character in your Pathfinder game. Presently, we have three witch base classes, a warlock class, several traditions, new uses for skills, new feats, new hexes and powers, dozens of prestige classes, new archetypes, and several multi-class paths; and we have compiled hundreds of spells and lots of Open Gaming Content. No two witches ever need to be the same again!
For the Game Masters we also include witch-related monsters, new magic items, ritual magics, and adventure hooks for your game. Get your witches involved on quests that mean something to them or provide some witch-centric adventures.
