There can only be 1 face-up "Earthbound Immortal" monster on the field. If there is no face-up Field Spell Card on the field, destroy this card. Your opponent cannot select this card as an attack target. This card can attack your opponent directly. When this card is removed from the field, except by its own effect, destroy all face-up monsters your opponent controls, and inflict 800 damage to your opponent for each monster destroyed.
