Eye Beam

Using your Eye of the Elements you can cast an Eye Beam at any creature you can see using a bonus action. When you cast the spell, you can make a ranged spell attack against a creature within sight. On a hit, the target takes elemental damage equal to 1d6 + your spellcasting ability modifier. 

Cantrip Upgrade. The damage increases by 1d6 when you reach levels 5 (2d6), 10 (3d6), and 15 (4d6).
