Deep Sea

You make a spell attack to summon the deep sea to crush a creature of your choosing forming a water sphere around them, encasing them in a 10-foot sphere of water. They must make a Constitution Saving Throw taking 4d8 Force Damage on a fail or half-damage on a success. At the end of their turn the creature makes a Dexterity Saving Throw to try and swim out of the sphere, if they fail they take 2d8 Force Damage.

At Higher Levels: When you cast this spell using a spell slot of 6th level or higher, the damage die increases by 1d8 for each slot level above 5th.
