Wall of Storms

A wall of crackling storm clouds forms at a point you choose 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 is opaque and lasts for the duration.

When the wall appears, each creature within its area must make a Dexterity saving throw, taking 5d8 lightning damage on a failure, or half as much on a successful one. Any creature that attempts to pass through the wall must also make this saving throw.

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