Sure, you could hire some minions to take care of your dungeon, but the upkeep on them can get pretty crazy. Why not just build yourself some guardians instead? That's where golems come in. And if you want some more variety in your golems, Skirmisher Publishing has released New Golems of the Labyrinth for you.
From the website:
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 publication 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. They include the Cerebral, Ectoplasm, Flesh-and-Blood, Gas Metal, Leaf, Lightning Rod, Magic, Particulate, Shield, and Water Chariot Golems.
“New Golems of the Labyrinth” also comes with four Cardstock Characters™ miniatures that storytellers can add to their tabletop games.
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.
