Blood Sense.

Can pinpoint by scent the location of creatures that aren’t Undead or Constructs within 30' of it.

False Appearance.

While motionless indistinguishable from collection of snowflakes whether resting on the ground or carried by natural winds. It loses this trait if it has consumed blood in the last 24 hrs.

Rust Vulnerability.

The large amount of iron in its diet makes it susceptible to effects that harm ferrous metal such as the rust monster’s Antennae.

Swarm.

Can occupy another creature’s space and vice versa and flurry can move through any opening large enough for a Tiny crystalline Aberration. Can't regain hp or gain temp hp.
