Bag of Teeth

This small sack is made of fish skin and contains a handful of piranha teeth. By opening the bag and scattering its contents in a body of water, the user creates a swarm of quippers.

The swarm is average in all regards and remains for 10 minutes. The swarm moves toward and attacks the closest living creature in the water, and the user has no control over its target or direction of travel. If no other creature is available, the swarm remains where it was summoned and attacks the first creature that approaches.
