Arc Lightning

A crackling bolt of lightning streaks toward a target within range and surges through them. Make a ranged spell attack against the target. On a hit, the target takes 3d8 lightning damage and it cannot use reactions until the end of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage (both initial and later) increases by 1d8 for each slot level above 2nd.
