You impose the pressure of the deep sea upon a creature that you can see within range. The target must succeed on a Strength saving throw or take 8d6 bludgeoning damage and become blinded and restrained for the duration. At the end of each of its turns, the target can make another Strength saving throw. On a success, the spell ends on the target.

The target has advantage on the saving throw if it has a swimming speed and automatically succeeds if it is immune to the effects of being underwater at a depth greater than 100 feet.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6, for each slot level above 4th.
