    Special Traits

    • Feeding Frenzy. The swarm has advantage on attack rolls against creatures that do not have all their hit points as a result of having taken piercing or slashing damage (including from the swarm itself).
    • Swarm. The swarm can occupy one or more other creatures’ spaces and vice versa, and the swarm can move through an opening large enough for a Tiny piranha. The swarm can’t regain hit points or gain temporary hit points. While the swarm occupies the space of a Large or larger creature, the swarm has from cover. Weapon attacks directed at the swarm which miss, but which would have hit without the bonus from cover, instead hit the creature sharing the space.
    • Water Breathing. The swarm can only breathe underwater.


    • Multiattack. The swarm makes up to three Bite attacks, each on a different target.
    • Bite. Melee Weapon Attack: +4 to hit, reach 0 ft., one creature in the swarm’s space. Hit: 12 (4d4 + 2) piercing damage or 7 (2d4 + 2) piercing damage if the swarm has half of its hit points or fewer.
