Energized Fireball

A small ball of flames and electrical energy forms from your hands. After crushing it, a bright streak flashes from your pointing finger to a point you choose within range, blossoming with a low roar and crackling into an explosion of flame and lightning. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 6d6 fire damage and 2d6 lightning damage on a failed save, or half as much damage on a successful one.

The fire and electricity spread around corners. It ignites flammable objects in the area that aren't being worn or carried and electrocutes metallic objects.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for either fire or lightning damage for each slot level above 4th.
