Immunity to Magic

A brass 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 magical attack that deals cold damage slows a brass golem (as per the slow spell) for 1d6 rounds, with no saving throw. A magical attack that deals fire damage breaks any slow effect on the golem and heals 4d8+20 points of damage.
