Up to ten 10-foot cubes, which you can arrange as you wish, appear. Each cube must have at least one face touching another cube's face. Each creature in the area makes a Dexterity save. It takes 7d10 fire damage on a failed save, or half 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 this spell.
