Electrical Shock

You create one small stroke of lightning that targets one creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 lightning damage. If you roll a 20 on the attack, the target must succeed on a Constitution Saving Throw or be paralyzed until the end of its next round.

This spell's damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
