Swarming Bites
Each enemy in the swarm's space takes 5d6 piercing (DC 23 reflex). A creature that fails the saving throw also takes 1d4 bleed and is Clumsy 1 as long as it's taking bleed damage.
When a massive creature such a dinosaur or giant dies in skin beetle territory, the industrious vermin swarm together.
Skin beetles are found in most environments that can sustain life, from cold, dry steppes to dense, humid jungles. They use their complex multi-jointed mandibles to strip the skin and flesh from recently deceased creatures with almost surgical precision. While skin beetles eat most of what they remove, they also preserve chunks for later by coating it in special salivary secretions similar to formaldehyde. The skin beetle rolls this coated flesh into a ball, then stores it under an exposed tree root or rock for leaner times. Signs of skin beetle activity include excoriated skeletons and the smell of the beetles' preservative saliva.
Umasi Beetle Masters
Though best known for flaying carrion, skin beetles can also heal gravely wounded individuals. Skin beetles can graft preserved flesh onto a dying animal or humanoid. The end result isn't pretty, but it sometimes works. From the perspective of the healed, the blessing can be mixed, as the beetle's surgery often transforms the subject into a patchwork aberration called an @UUID[Compendium.pf2e.pathfinder-bestiary-3.Actor.Umasi].
Umasi created by skin beetles sometimes develop supernatural connections to their insectoid saviors. Such umasi can command skin beetles to harvest more flesh to keep their decaying bodies intact.
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.
