Traits

Constructed Nature

The swarm doesn't require air, food, drink, or sleep.

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 insect. The swarm can't regain hit points or gain temporary hit points.

Spider Climb

The swarm can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

Web Sense

While in contact with a web, the swarm knows the exact location of any other creature in contact with the same web.

Web Walker

The swarm ignores movement restrictions caused by webbing.

Actions

Bites

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