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.
Nibble
Each enemy in the squirrel swarm's space takes 1d6 piercing damage (DC 15 reflex save).
Scrabbling SwarmThe squirrels clamber over the creatures in their space. Each such creature must succeed at a DC 17 reflex save or become Clumsy 1 as long as it remains in the swarm's space.
Descending with a shriek, a swarm of squirrels is a menace to foes, crawling in and out of pockets and clothing, biting and scratching as it goes. Though squirrels are usually independent, they might form into swarms when cornered or if a predator creates enough of a recurring threat that the little creatures need to gang up.
Squirrels' ability to dart into sticky situations, extract berries or nuts from the most precarious of circumstances, and then hide their loot from prying eyes make them nature's thieves in trees. Their cute appearance-soft fur, big eyes, and fluffy tails-makes them inconspicuous and endearing, at least to some. Their reputation among humanoids is split between those who consider them cute little creatures and others who believe they're vermin.
Usually no more than a nuisance on their own, they can become a dangerous annoyance under the command of a druid, fey, or other creature that practices nature magic or is otherwise tied to the natural world. With their ability to reach remote places, excellent eyesight, and adept problem-solving, squirrels can perform effective reconnaissance for druids.
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
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.
