Spider Swarm
Level 0Abilities
The spider swarm has imprecise tremorsense to detect the vibrations of creatures touching its web. Tremorsense allows a monster to feel the vibrations through a solid surface caused by movement. It is an imprecise sense with a limited range (listed in the ability). Tremorsense functions only if the monster is on the same surface as the subject, and only if the subject is moving along (or burrowing through) the surface.
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.

Description
An abundance of food, the sudden hatching of a clutch of eggs, or magical influence can cause smaller spiders to gather in terrifying, deadly masses.
Few everyday vermin inspire as much dread as the infamous spider.
