Swarm. The swarm can occupy another creature’s space and vice versa, and the swarm can move through any opening large enough for a size Tiny insect. The swarm can’t regain hit points or gain temporary hit points.

Weak Poison. A creature reduced to 0 hit points by a swarm of centipedes is stable but poisoned for 1 hour, even after regaining hit points, and paralyzed while poisoned in this way.

Actions


Bites. Melee Weapon Attack: +3 to hit, reach 0 ft., one target in the swarm’s space. Hit: 10 (4d4) piercing damage, or 5 (2d4) piercing damage if the swarm has half of its hit points or fewer.

This represents a mass of centipedes.
