Chromatic Bolt

You hurl a mote of elemental energy at a creature or object within range. You choose cold, fire, lightning, or radiant for the type of mote you create, and then make a ranged spell attack against the target. On a hit, the target takes 1d6 damage of the type you chose. 

This spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
