Crackling Hand

Your dominant hand is imbued in a crackling layer of electricity, which concentrates at your fingertips. You can make a melee spell attack at a creature within contact range, stabbing at them to deal a 1d12 of lightning damage. 

This spell's damage increases by 1d12 when you reach 5th level (2d12), 11th level (3d12), and 17th level (4d12).
