Blue Hell Flame

A bright blue inferno flashes from your feet to around you. Each creature in a 150-foot-radius sphere around that point must make a wisdom saving throw. They take 10d10 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 and turns them into ash.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 2d8 for each slot level above 3rd.
