Abilities

Swarm Minddefensive

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.

Trigger A creature walks into the room --- Effect The sprites scream "Surprise!," attempt a opossum flyby Strike, and roll initiative.

Description
