Chromatic Cone

A blast of elemental energy erupts from your hands. Choose acid, cold, fire, lightning, poison, or thunder. Each creature in a 40-foot cone must make a Dexterity saving throw. A creature takes 7d8 damage of the type you chose on a failed saving throw or half as much damage on a successful one. At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th.
