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 MindThis 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.
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.
Traits
Something of uncommon rarity requires special training or comes from a particular culture or part of the world. Some character choices give access to uncommon options, and the GM can choose to allow access for anyone. Less is known about uncommon creatures than common creatures. They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.
AnimalAn animal is a creature with a relatively low intelligence. It typically doesn't have an Intelligence attribute modifier over –4, can't speak languages, and can't be trained in Intelligence-based skills.
SwarmA swarm is a mass or cloud of creatures that functions as one monster. Its size entry gives the size of the entire mass, though for most swarms the individual creatures that make up that mass are Tiny. A swarm can occupy the same space as other creatures and must do so in order to use its damaging action. A swarm typically has weakness to effects that deal damage over an area (like area spells and splash weapons). Swarms are immune to the grabbed, prone, and restrained conditions.
