2 Level 5 monsters
You can also Xyz Summon this card by using a Rank 4 "D/D/D" Xyz Monster you control as the Xyz Material. (Xyz Materials attached to that monster also become Xyz Materials on this card.) Once per turn, during either player's turn, if you took any effect damage this turn: You can detach 1 Xyz Material from this card, then target 1 face-up monster on the field; it loses 1000 ATK and DEF, and if it does, inflict 1000 damage to your opponent. If this card is sent from the field to the Graveyard: You can send 1 "D/D" or "Dark Contract" card from your Deck to the Graveyard.
