Azamarr's Sizzling Uppercut

Your hand crackles with yellow sparks as it flies up towards your opponent's chin. Make a melee spell attack against the target. If the attack hits, the creature takes 1d12 bludgeoning damage and 2d12 lightning damage. The target must succeed on a DC12 Constitution saving throw or be stunned until the start of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the lightning damage increases by 1d12 for each slot above 3rd.
