Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
[ Pendulum Effect ] Once per turn: You can pay 500 LP, then target 1 face-up monster your opponent controls; it loses 500 ATK (even if this card leaves the field). Unless you have a "D/D" card in your other Pendulum Zone, this card's Pendulum Scale becomes 5. ---------------------------------------- [ Monster Effect ] When this card is Normal Summoned: You can add 1 face-up DARK Pendulum Monster from your Extra Deck to your hand.
