    A piranha swarm turns quiet water into a churning red surface once blood enters it. The fish scatter from an uninjured intruder, then gather faster than a wound can be bound.

    Special Attack

    Feeding Rush: piercing, every wounded creature sharing the swarm's water takes 2d4 damage at the end of the round. An unwounded creature takes 1d4 damage instead.

    Special Defense

    Scattered Bodies: ordinary weapon attacks deal only 1 damage to the swarm. Nets, broad blows, lightning through the water or draining the pool deal full damage. Leaving the water ends its attack immediately.
