Darkened Fireball

A bright flame roars to life in your palm quickly darkening to a black purple streaked ball malicious fire. You can launch this chaotic flame to a point you choose within range the attack lands & then blossoms with a low symphony of sounds into a hue of purplish exploding fire. Each creature in a 15-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 5D6 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. the damage increases by 1d6.
