False Appearance. While the carnivorous remains motionless, it is indistinguishable from normal crystal formations.
Subsonic Hum. Any creatures that starts it's turn within 30 feet of the crystal must make a DC 15 Constitution saving throw. On a failed save, the creature is stunned until the end of their next turn. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the crystal's Subsonic Hum for the next 24 hours.
Slam. Melee Weapon Attack: +10 to hit, reach 5ft., one target. Hit: 41 (8d8 + 6) bludgeoning damage. If the target is medium or smaller, it is grappled (escape DC 15) and restrained until the grapple ends.
Crystallise. The crystal attempts to engulf the creature grappled by it. The creature must succeed a DC 15 Consitution saving throw or it becomes paralyzed. On the following round if the crystal uses its Crystallise ability and the creature is paralyzed, it must succeed a DC 15 Constitution saving throw or become petrified. In 4 days the petrified creature shatters and becomes a new carnivorous crystal killing the creature. The creature can be cured by a greater restoration spell or other magic.
Split. When a crystal that is medium is subjected to bludgeoning or thunder damage, it splits into two new crystals if it has at least 10 Hit Points. Each new crystal has Hit Points equal to half the original crystal's, rounded down. New crystals are one size smaller than the original crystal.
