From publisher blurb:
Of all the creatures found guarding hoards of lost treasure, Golems — constructs created by powerful spell casters from specific sorts of materials — are among the most interesting and dangerous. Some might even constitute treasure in and of themselves.
Golems crafted from materials like clay, flesh, stone, iron, amber, bone, bronze, and wood are familiar to the players of OGL-based games, but they represent just a narrow glimpse of the possibilities for such creatures. This mini-sourcebook contains 10 new sorts of Golems, all of them are very different from the basic models and some of them pretty weird, that GMs may find useful in making their campaigns more interesting and unpredictable.
Monsters in this publication are stat'ed for the "Basic" version of the OGL system and can easily be modified or used as-is with any related games.
