Cruel Sun

A large intensely bright ball of fire appears at the tip of your finger which you then direct in a single direction up to 300 feet away. Upon reaching the targeted distance the magic explodes into that of a miniature sun. Each creature in a 30-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 6d12 fire damage on a failed save, or half as much damage on a successful one.

The fire spreads around corners. It 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 damage increases by 1d12 for each slot level above 6th.
