Dragon's Ember

A bright sphere burns from your raised hands to a point you choose within range and then blossoms with a low roar into an explosion of flame. Each creature in a 15-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 10d6 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 are being worn or carried and burns the area effected for 2 minutes and blinds for a round everyone that is 5ft near the explosion.

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.
