This spell is only possible at least 15 feet underwater. If it is cast outside of a body of water, it has no significant combat effect.
At a point of your choosing up to 60ft away from you, a 15 foot cube of free water is immediately destroyed. (water in containers and creatures is unaffected) Each creature within the area of effect must make a Dexterity saving throw. On a failed save, a creature is slammed by the water rushing in to fill the void and takes 4d12 bludgeoning damage and is deafened and stunned until the end of your next turn. On a successful save, the creature takes half as much damage and escapes the stun and deafening. If more than one creature inside of the cube fails their save, they are smashed against each other and take an additional 1d12 damage.
At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the area of effect is increased by 5 feet per level.
