Chain Golems are constructed as guardians for libraries, palaces, and treasure hoards, often integrated into room decoration or placed inconspicuously as a coil of chain. When disturbed or called to defend their hoards, chain golems rise up into an animated chain that moves like a swift snake, lashing out in all directions up to 15 feet. Size and appearance vary, but the average specimen is made of heavy chain, 300 feet long and weighing 3,000 pounds.

Lash attacks may be distributed between multiple targets or focused on a single target. When three successful attacks are made on a target in a single round, the chain golem has achieved a grappling hold and may apply a special attack to the victim the following round: constriction, tearing, or hurling. Characters thus held may escape with a successful save vs. Death Ray, per the wrestling rules in the Basic Fantasy RPG Core Rules.
