While the equipped monster battles, your opponent cannot activate any Spell/Trap Cards until the end of the Damage Step. If an attack is declared involving the equipped monster: Negate the effects of face-up Spells/Traps your opponent controls until the end of the Damage Step (even if this card leaves the field). When the equipped monster destroys an opponent's monster by battle: You can destroy all Spells and Traps your opponent controls. When this face-up card in a Spell & Trap Zone leaves the field, that player takes 3000 damage.
