Bloodfire

Magical energy surges through your body before violently erupting outward in a fiery explosive blaze in a 30-foot-radius sphere centered on yourself. Each creature caught in the radius must make a Dexterity saving throw. A target takes [roll]10d10[/roll] fire damage on a failed save, or half as much damage on a successful one.

You will always take self-inflicted damage equaling half the total damage of the spell upon casting.

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 [roll]1d10[/roll] for each slot level above 6th.
