Hydaelyn

You create an aquatic prison around a large or smaller creature you can see within range. The target must succeed on a Dexterity saving throw or take 3d10 cold damage and be engulfed in a bubble of water, which acts as a prison. On a success, the target takes half damage and suffers no other effects. The engulfed creature can't breathe, is restrained, and takes 3d10 cold damage at the start of each of its turns. The creature can attempt to escape by making a Strength saving throw against your Spell save DC.
