Twin Elven Fireball

Two bright streaks flash from your pointing finger to two points you choose within range and then blossom with a low roar into an explosion of flame. Each creature in a 5-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 6d4 fire damage on a failed save, or half as much damage on a successful one.

Sphere's can overlap causing 12d4 fire damage to the targets.

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 4th level or higher, each sphere's damage increases by 1d4 for each slot level above 3rd.
