Any iron or iron alloy item you touch crumbles into rust. If the item is so large that it cannot fit within a 3-foot radius, a 3-foot radius volume of the metal is rusted and destroyed.
You may employ rusting grasp in combat with a successful caster check. Rusting grasp used in this way instantaneously destroys 1d6 points of AC gained from metal armor through corrosion.
Weapons in use by an opponent targeted by the spell are more difficult to grasp. You must succeed on a caster check against the weapon. A metal weapon that is hit is destroyed. Striking at an opponent’s weapon provokes an attack of opportunity. Also, you must touch the weapon and not the other way around.
Against a creature with the metal creature, rusting grasp instantaneously deals 3d6 points of damage + 1 per caster level (maximum +15) per successful attack. The spell lasts for 1 round per level, and you can make one caster check per round.
