High ammounts of voltage run through you, sparking and cracking around you. Whoever you target next will get a strong and potent zap through their body

If the target is within the range of 10ft you can point at them and send a dose of high voltage lightning through them from your body, damaging them by 1d4+1. If the target fails a Con saving throw based on your spell save DC, they gain vulnerability to lightning until end of your next turn.
