You clamp down on a target, attempting to deal damage and keep them in place. Make a melee attack roll. On a hit, the target takes 1d6 + MOVE water damage and is grappled. At the beginning of each of its turns, it may attempt to escape with a STR save against your Move DC. On your subsequent turns, while you are grappling a creature with this move, you can activate it again as a bonus action, with an automatic hit, dealing 1d6 water damage.
