Arcane Flux

You launch an arcane bolt of energy towards a creature within range. You make a ranged spell attack against the creature. On a hit, the target takes 2d4 force damage. The attack splits and hits two targets within 10 feet of the original target dealing 1d4 force damage to each.

At higher levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d4 for each slot level above 1st.
