Immunity to Magic

Feats

A clay golem is immune to any spell or spell-like ability that allows spell resistance. In addition, certain spells and effects function differently against it, as noted below. A disintegrate spell slows the golem (as per the slow spell) for 1d6 rounds with no saving throw, and deals 1d12 points of damage. Any magical attack against a clay golem that deals acid damage heals 4d8+20 points of damage.
