Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Once per turn: You can pay LP in multiples of 100; other face-up monsters on the field lose that much ATK. Once per turn: You can target 1 monster on the field with ATK less than or equal to this card's; destroy it. If this card is destroyed by battle or card effect: All face-up monsters on the field lose 1000 ATK.
