churning earth

Choose a point you can see on the ground within range. a 20 foot cube of the earth starts moving like an ocean. A creature takes 3d12 bludgeoning damage. And is restrained, blinded, deafend and can't breath. Additionally, the ground in that area becomes difficult terrain until cleared. Each 5-foot-square portion of the area requires at least 1 minute to clear by hand.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d12 for each slot level above 4th, also the size of the cube increases by five feet.
