Spider Swarm

Creature 0 — animal, swarm

SnareLANDVERTICALanimalswarm

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.

Abilities

Web Sense — 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.
Swarm Mind — 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.
Spider Swarm Venom (poison) — Saving Throw DC 14 Fortitude

Maximum Duration 4 rounds

Stage 1 1 poison and Enfeebled 1 (1 round)

Stage 2 1d4 poison and enfeebled 1 (1 round)
Swarming Bites — Each enemy in the spider swarm's space takes 1d4 piercing damage with a DC 14 Reflex save.

A creature that fails its save is exposed to spider swarm venom.

WORKS WELL WITH

WeaverLAND / VERTICALArea magic ignores the swarm's resistance to piercing and slashing, clearing the space a melee party would struggle to break.
CrasherLAND / VERTICALA bludgeoning-capable bruiser can actually damage the swarm while it ties up the party's positioning.

PUNISHES

✖ melee reliance✖ clumping✖ precision reliance
Avoid stacking multiple area-denial swarms; a redundant obstacle once the party finds an area answer.
