Vortex (Recharge 4-6). The devil shark creates a vortex of water within 30 feet of it that lasts for 1 minute. The vortex is 5 feet in diameter and up to 30 feet tall. A creature occupying the space where the vortex appears or entering the vortex for the first time on a turn must make a DC 18 Dexterity save or be restrained and take 2d8 bludgeoning damage. As an action, a creature can free itself or another creature from a vortex by succeeding on a DC 18 Strength check. The devil shark loses its Freezing Breath action.
