Arcane Bolts

Two bolts of magical energy circle around your wrist until the spell ends or you lose concentration, which then the bolts burst harmlessly. When the spell is cast and each turn after you cast this spell, as a Bonus Action, you can make a ranged spell attack using these bolts. The bolts fire beams that can reach up to 95 ft. The beams all strike simultaneously, and you can direct them to hit one creature or several. The damage type of the beams is whatever energy the bolts are, which can be any non-Piercing, non-Bludgeoning, non-Slashing, damage type. The damage each beam does is 1d6. 

Using a Higher-Level Spell Slot. The spell creates one more bolt for each spell slot level above 2.
