For the Duration you must remain within 30 ft. of your initial casting spot or else concentration will be broken. the spell must also be cast outdoors or else the spell won't function properly. You bring down 1d4 + 2 5 foot wide balls of fire onto a spot of your choice within range. each round you reroll the amount and decided where the land. when they land, they create a 10-foot-radius sphere of fire and a 5 foot wide crater where they land. each creature within the 10-foot-radius sphere centered on those points must make a dexterity saving throw. A target takes 4d6 fire damage and 2d6 non-magical bludgeoning damage on a failed save, or half as much on a successful one.

The fire spreads around corners. ignites flammable objects in the area that aren't being worn or carried.

At Higher Levels. when you cast this spell using a spell slot of 7th level or higher, the Fire and Bludgeoning damage both increase by 1d6 for every spell slot above 6th level.
