Heatsense. The swarm can pinpoint the location of creatures emitting heat such as warm-blooded Beasts and Humanoids within 30' of it.

Spider Climb. Difficult surfaces even ceilings no ability check.

Swarm. Can occupy another creature's space and vice versa and swarm can move through any opening large enough for a Tiny elemental. Can't regain hp or gain temp hp.
