Force Pulse (1/Day). Ank'rathum radiates a wave of gravitational energy in a 30 ft. sphere centered on itself. All other creatures and objects not being carried or worn and weighing less than 300 lbs. within 30 feet of it must make a DC 16 Constitution saving throw. On a failure, the creature or object is moved 30 ft. either directly towards or directly away from Ank'rathum. On a successful save, a creature is unmoved.
Gravity Aura. Creatures that end their turn with 20 ft. of Ank'rathum are subject to it's crushing gravitational aura. A creature that ends it's turn in the aura must succeed on a DC 16 Constitution saving throw or suffer 2d8 force damage and are knocked prone. If the saving throw is successful, the target takes half the force damage and isn't knocked prone.
