Compressed Fireball

A 20ft sphere of fire appears in your hand before rapidly compressing into a much smaller 5-foot sphere, this sphere can be thrown 180ft. Each creature in a 5-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 11d6 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 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
