Monster Mash II: A Midsummer Night's Dream

A fantasy roleplaying supplement for Basic-era games that lets players take the roles of monsters rather than traditional heroes. It includes 12 faerie- and sylvan-themed classes, including bugbears, centaurs, hamadryads, leprechauns, nymphs, pixies, púc​as, satyrs, werebears, werefoxes, woodwoses, and faerie witches. The book also adds spells for clerics, druids, illusionists, and magic-users, along with occult powers and ritual spells for faerie witches. It is compatible with Old-School Essentials and other Basic-era games, and requires the Old-School Essentials Core Rules.
