More teeth and fury than body, few fish command as much fear and anxiety as the piranha. They move almost exclusively in schools, overwhelming larger creatures with sheer numbers and ferocity. Piranhas aggress toward sudden disturbances in the water and can smell blood from far away. Harvested piranha teeth serve as excellent cutting tools.

Abilities

Blood Scent — The piranha swarm can smell blood in the water from up to 1 mile away.
Swarm Mind — This monster doesn't have a single mind (typically because it's a swarm of smaller creatures), and is immune to mental effects that target only a specific number of creatures. It is still subject to mental effects that affect all creatures in an area.
Feeding Frenzy — Each enemy in the swarm's space takes 2d6 piercing damage (DC 20 Reflex save).

A creature that fails the save also takes 1d6 bleed and takes a -2 circumstance penalty to their Reflex saves against Feeding Frenzy while this damage continues, as the piranhas' frenzy increases in intensity when they smell blood.

SniperAQUATICRanged attackers exploit the Reflex penalty imposed by the swarm's feeding frenzy to land critical shots on debuffed targets.
FlankerAQUATICMobile aquatic strikers pick off isolated enemies fleeing the swarm's occupied space, punishing disengagement attempts.
