Daemones Respiratio

A storm made up of sheets of roaring flame appears from deepest of earth in a location you choose within range after saying the conjuration DE PROFUNDISSIMIS INFERIS, ADIURO DAEMONORUM RESPIRATIORUM LEGIONUM ANTIQUISSIMUM, as area of the storm consists of up to three hundred forty five 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 a Dexterity saving throw, which is temporary thanks to hellish demonic forces. It takes 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 are not being worn or carried. If the caster choose, plant or mystical life in the area is unaffected by this spell.
