If you have a base arms equipped, transform it into this, then equip this. (Put it under this in your arms zone.) When this defends, you may destroy a card under it. If you do, gain control of target item with cost 0 or 1 controlled by the attacking hero. Temper (When the combat chain closes, if this defended, put a -1DEFENSE counter on it, then if it has 0DEFENSE, destroy it.)
