Agheel's Flame

You roar, lifting into the air and channeling the head of Agheel to spew flaming breath. You gain a flight speed of 15 feet for the duration. Until the spell ends, you can use your action to breathe fire in a 30-foot cone. Each creature in the area must make a Dexterity saving throw. A target takes 5d6 fire damage on a failed save, or half as much 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 5th level or higher, the damage increases by 1d6 for each slot level above 4th.
