Brittle (Ex)

Bludgeoning and sonic attacks can inflict critical hits on a carnivorous crystal. A successful critical hit from such attacks causes the carnivorous crystal to split, even if the attack causes no damage. The crystal remains immune to precision-based damage, such as damage from sneak attacks.

Crystallize (Ex)

A creature entrapped by a carnivorous crystal’s attack must succeed at a DC 16 Fortitude save each round or become helpless. If a helpless creature fails this save, it becomes petrified as its body crystallizes. In 1d4 hours, the petrified victim shatters and a new carnivorous crystal emerges from the remains.

Entrap (Ex)

A carnivorous crystal’s attack encases its target in crystal and restricts the creature’s movement. The target must make a DC 18 Fortitude save or become entangled for the listed duration. If a target is already entangled by this ability, a second entrap attack means the target must make a Fortitude save or become helpless for the listed duration. A target made helpless by this ability is conscious but can take no physical actions (except attempting to break free) until the entrapping material is removed. An entangled creature can make a Strength check (at the same DC as the entrap saving throw DC) as a full action to break free; the DC for a helpless creature is +5 greater than the saving throw DC. Destroying the entrapping material frees the creature.

Subsonic Hum (Su)

An active carnivorous crystal gives off supernatural sonic vibrations. Any living creature starting its turn within this aura must succeed at a DC 18 Fortitude save or be Stunned”>stunned for 1 round. A creature that successfully saves cannot be affected by the same carnivorous crystal’s subsonic hum for 24 hours. This is a sonic mind-affecting effect.


Environment any underground
Organization solitary, colony (2–4), or formation (5–10)

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.
