Golem Armor: This enormous suit of black iron +10 full plate armor increases the wearer’s size by one category (to a maximum of Colossal). The wearer gains a +10 enhancement bonus to Strength and is rendered immune to mind-affecting effects, poison, disease, and similar effects. He or she is not subject to critical hits, nonlethal damage, ability damage, energy drain, or death from massive damage. Golem Armor is immune to rust attacks. The wearer of Golem Armor gains damage reduction 15/adamantine. He or she also cannot regain hit points by any means (mundane or magical) while the armor is worn. It requires 1 hour to don or extract oneself from Golem Armor.
