Chromatic Explosion

You point to a location within range that you can see. An explosion of energy erupts from that point. You choose acid, cold, fire, lightning, poison, or thunder for the type of explosion you create. Each creature you choose in a 20-foot-radius sphere centered on that point must make a Dextertiy saving throw. A creature takes 6d10 damage of the type you chose on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 6th or higher, the damage increases by 1d10 for each slot level above 5th.
