 "The unusual physical construction of warforged makes them vulnerable to certain spells and effects that normally don't affect living creatures. A warforged takes damage from 
heat metal and 
chill metal as if he were wearing metal armor. Likewise, a warforged is affected by 
repel metal or stone as if he were wearing metal armor. A warforged is repelled by 
repel wood. The iron in the body of a warforged makes him vulnerable to 
rusting grasp. The creature takes 2d6 points of damage from the spell (Reflex half; save DC 14 + caster's ability modifier). A warforged takes the same damage from a rust monster's touch (Reflex DC 17 half). Spells such as 
stone to flesh, 
stone shape, and 
wood shape affect objects only, and thus cannot be used on the stone and wood parts of a warforged."
