Chromatic Plume

You unleash a multi-colored blast of chromatic energy in a 60-foot cone originating from yourself. Each creature within that area must make a Dexterity saving throw. On a failed save, a creature takes 2d6 acid damage, 2d6 cold damage, 2d6 fire damage, 2d6 lightning damage, 2d6 poison damage and 2d6 thunder damage. On a successful save, a creature takes half damage.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, one damage type of your choice increases by 1d6 for each slot level above 6th.
