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.

Cute But Deadly (aura, visual)

30 feet. The sight of these bunnies with their red glowing eyes and sharp teeth is so unsettling that upon seeing them a creature must attempt a DC 17 Will save. On a failure, that creature becomes Frightened 1 (or Frightened 2 on a critical failure) and cannot lower their frightened condition lower than 1 while within the aura. A creature that succeeds at its save is temporarily immune to all abyssal bunny swarm's cute but deadly auras for 1 minute.

Speed 20 feet

Swarming Bites

Each enemy in the swarm's space takes 1d6 piercing damage (DC 14 basic Reflex save). A creature that critically fails its save is becomes Clumsy 1.
