A storm made up of sheets of roaring flame appears in a Location
you choose within range. The area of the storm consists of up to ten 10-foot cubes, which you can arrange as you wish. Each cube must have at least one face adjacent to the face of another cube. Each creature in the area must make Dexterity
saving throw. It takes 7d10 fire damage
on a failed save, or half as much damage on a successful one.
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 this spell.
