Chromatic Sphere

A bright streak flashes from your pointing finger to a point you choose within range and then blossoms with a low roar into an explosion of an elemental damage type. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 fire damage on a failed save, or half as much damage on a successful one. You may instead choose to change the fire damage to any damage type from the list at the end of this description

The damage spreads around corners. It ignites flammable objects in the area that aren't being worn or carried if it is fire, or lightning damage.\n\nAt Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for each slot level above 4th.

List of valid damage types: ( Poison, Acid, Fire, Cold, Radiant, Necrotic, Lightning, Thunder, Force, Psychic )
