Monster Mash: Monster Classes for Basic-Era Games

This Old-School Essentials-compatible supplement lets players take the roles of monsters rather than traditional dungeon-delving heroes. It includes 13 horror-themed classes, including golems, cat folk, ghosts, haglings, hobgoblins, revenants, shadow elves, shades, werewolves, wererats, vampires, profane necromancers, and gothic witches. The book also adds new spells for several classes, along with occult powers and ritual spells for gothic witches.
