Wall of Detritus

You pull all the rubbish and loose stones in the area into a wall of detritus within range. You can make the wall up to 60 feet long, 20 feet high, and 1 foot thick, or a ringed wall up to 20 feet in diameter, 20 feet high, and 1 foot thick. The wall partially obscures vision (treat as thick fog) and lasts for the duration.

When the wall appears, each creature within its area must make a Dexterity saving throw. On a failed save, a creature takes 2d6 bludgeoning damage, or half as much damage on a successful save.

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 2nd.
