Chromatic Explosion

You hurl a sphere of energy at a area that you can see within range. You choose acid, cold, fire, lightning, poison, or thunder for the type of orb you create. Each creature in a 20-foot radius must make a Dexterity saving throw. A target takes 8d6 elemental damage on a failed save, or half as much damage on a successful one. The Effect spreads around corners and effects objects in the area that aren’t being worn or carried appropriate to the damage type.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the saving throw increases by 1 for each level the spell is upcasted.
