Black lightning

Dark lightning begins to form around your arm and arch into your palm forming a ball. Once you thrust your hand forward the ball releases and flies rapidly to your target.

You can target 1 creature up to 120ft away that you can see, and direct the ball of black lightning toward them. The creature must succeed on a Dexterity saving throw or take 3d10 lightning damage and be stunned until the end of your next turn. If the target succeeds it takes half damage and resists the stun effect

At Higher Levels. When you cast this spell using a spell slot of 4th or higher level, the damage increases by 1d10 for each slot level above 3rd.
