Fire Storm

A storm made of crackling sheets of flame appears at a location of your choice within range of the spell. The storm’s area consists of up to 10 5-meter cubes, which you can arrange as you like. Each cube must have at least one face adjacent to the face of another cube.

Each creature in the area must make a Dexterity saving throw. It takes 7d10 incinerating damage on a failure, or half as much on a success.

The fire damages objects in the area and ignites flammable objects that aren’t being worn or carried. If you choose, plant life in the area is unaffected by the spell.
