From publisher blurb: The Valley of the Rock Baboons is another hex in the Rawhide Gang cluster. It features three dungeons (a mini-shrine to a baboon god, a brigand outpost, and the redoubt of a long-dead illusionist) as well as rules for creating animated objects, legendary weapons (magical items that grow more powerful along with the wielder) and a monk class for Old School Essentials or other similar games.
