Electrolyze

Two bolts of oppositely-charged electricity streak towards the targets of your choice, eager to complete a circuit. Make two ranged spell attacks against one creature or two creatures within 15 feet of each other. You have advantage on the attack roll if the target is wet or made of water. On a hit, the creature takes 1d4 lightning damage.

This spell’s damage increases when you reach certain levels. When you reach 5th level (2d4), 11th level (3d4) and 17th level (4d4).
