Split (ex) - Slashing and piercing weapons deal no damage to the Carnivorous Crystal. Instead, it splits into two identical forms, each with half of the original's current hit points (round down). Pieces of the orignal continue to split until they have less than 10 hit points. Each piece dies at 0 hit points.
Freeze (ex) - When this creature holds still, it appears to be an inanimate object, allowing it to take 20 on stealth checks to hide in plain sight.
Brittle (ex) - This creature is brittle and sonic and bludgeoning damage automaticaly deal critical hit damage.
Subsonic Hum (su, Sonic, Mental, Aura) - This creature emits an aura of supernatural, sonic vibrations. Any living creature starting its turn within this aura must succeed at a CON save or be stunned (level 3) for 1 round. A creature that successfully saves cannot be affected by subsonic hum for 24 hours.

If the target misses the DC by more than 5, then it is instead completely restrained (level 3) as the crystal entraps it completely.

The facets of this crystalline formation shift and vibrate, as though in anticipation.
Natives of the endless caverns of the Plane of Earth, carnivorous crystals normally lead quiet existences, subsisting on minerals leeched from the surrounding rock. Living creatures, however, provide a veritable feast, as devouring the minerals in their bones and blood allows a crystal to reproduce in mere hours instead of years. Though lacking in anything that could be called intelligence, carnivorous crystals sense the living, and hunger for the sustenance trapped within their bodies. On the Plane of Earth and in the deepest caverns of the Material Plane, ancient carnivorous crystals grow without bounds, reaching incredible sizes.
