Silverfish Swarm

Creature -1 (uncommon) — animal, swarm

Pre-Remaster content. May include legacy alignment.

CrasherLANDVERTICALanimalswarm

It's uncommon for silverfish to congregate in sufficient numbers to constitute a swarm, but forgotten libraries or similar out-of-the-way places might harbor a multitude of the voracious pests. A common pest with a silvery carapace and an undulating, fishlike scuttle, the nocturnal silverfish infests homes and libraries throughout Golarion. These insects aren't typically dangerous, but their tendency to devour books and clothing often puts them at odds with larger creatures.

Abilities

Voracious Consumption — Action 1 minute

A silverfish swarm consumes up to 1 Bulk of paper, cloth, or similar material. It can consume up to 4 Bulk each day.
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.
Swarming Bites — Each enemy in the silverfish swarm's space takes 1d4 piercing damage (DC 14 Fortitude save). A creature that fails its save is Sickened 1.

WORKS WELL WITH

AnvilLAND / VERTICALA frontline body occupies the space the swarm wants to flow into, forcing more creatures to eat the Swarming Bites damage.
SnareLAND / VERTICALA controller that keeps foes standing still guarantees repeated Fortitude checks against the swarm's Sickened effect.
WeaverLAND / VERTICALA caster's area effects cover the space the swarm shares, since the swarm's own attacks are already area-based rather than single-target.

PUNISHES

✖ precision reliance✖ single-target focus✖ melee clumping
Avoid stacking with another weak-defense swarm; both share the same area-damage weakness and collapse together.
