This is a pretty fun little encounter for a bit of silliness to throw into your game. The PCs find themselves in the magical brewhouse of a wizard renowned for his ales. The problem is that his imp familiar has grown tired of the abuse he has to take and has put both the wizard, his spellbook and the assistant in peril.
The players are expected to save everyone as well as the spellbook before it is ruined through avoiding/surviving the devious use made of the various vats and equipment found inside the house.
This is definately a nice change from the ol' dungeon crawl when the DM is having one of those nights where he can't think up anything for the ongoing story.
