## Traits
 
***Keen Smell.*** The swarm has advantage on Wisdom ([Perception](rules/skills.md#Perception)) checks that rely on smell.
 
***Swarm.*** The swarm can occupy another creature's space and vice versa, and the swarm can move through any opening large enough for a Tiny rat. The swarm can't regain hit points or gain temporary hit points.
 
## Actions
 
***Bites.*** *Melee Weapon Attack:* `+2` to hit, reach 0 ft., one target in the swarm's space. *Hit:* 7 (`2d6`) piercing damage, or 3 (`1d6`) piercing damage if the swarm has half of its hit points or fewer.
