You can only activate this card when there are 'Don Zaloog', 'Cliff the Trap Nemover', 'Dark Scorpion - Chick the Yellow', 'Dark Scorpion - Gorg the Strong', and 'Dark Scorpion - Meanae the Thorn' face-up on your side of the field. During this turn, any of these 5 cards can attack your opponent's Life Points directly. In that case, the Battle Damage inflicted to your opponent by each of those cards becomes 400 points.'
