You can only activate this card when you have "Don Zaloog", "Cliff the Trap Remover", "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 the turn this card is activated, any of these 5 cards can attack your opponent's Life Points directly. In that case, the Battle Damage inflicted by each of those cards (that attack your opponent's Life Points directly) becomes 400 points.
