They spawn freely in vanilla 1.7. I must admit that I've never seen one spawn near a vanilla or mod witch hut. I've only ever seen them spawn in the Mystic Forest biome like you mentioned.Welcome to vanilla? I have seen too manybwitches in the Mystic Forest Biome from BoP to understand the idea behind them spawning in huts. Maybe in the wilds around their hut. Maybe if their hut wasn't impossible to get into without building a way in(or magic, I suppose). But yes, Jeb was very proud ofbwitches, and I don't understand why either.
