You can only activate 1 “Ring of Destruction” per turn. (1) During your opponent’s turn: Target 1 face-up monster your opponent controls whose ATK is lower than or equal to your opponent’s LP; destroy that face-up monster, and if you do, you take damage equal to that monster’s original ATK, and if you do that, inflict damage to your opponent equal to the damage you took.
