He waved a hand and two Spectral Skulls appeared.
As he dodged another attack from the demon, Dave sent both Skulls through a mirrored wall and sixteen Spectral Skulls emerged from all around the room.
Dave willed half of the Skulls to attack the demon and sent the other eight back into one of the walls.
The attack of the massed Skulls Staggered the demon even as the new multiples of Skulls emerged from the walls, eight Skulls from each of the eight walls.
Taking advantage of the momentary lapse in pursuit Dave ran away from the demon to the other side of the room. He began directing the flocks of Spectral Skulls, continuing to multiply them and then will a portion to attack the demon. He looked like a mad orchestra conductor, pointing, waving his arms and snapping his fingers.
