Elemental Orb

You create a small sphere of energy at a creature that you can see within range. You choose cold, lightning, water or thunder for the type of sphere you create, and then make a ranged spell attack against the target. On a successful hit targets take 3d8 damage. 

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st.
