Rust golems are composed of rusty metal and most often resemble suits of armour, though many are made to resemble rust monsters . A rust golem's touch causes metal objects to rust, and they are far mightier than most creatures with similar capabilities. A rust golem can exhale a cloud of powder that causes metal to corrode, as if the target were struck by one of its rusty limbs.
