Lightning springs from your hand to deliver a shock to a creature you that you make a ranged spell attack on. You have advantage on the attack roll if the target is wearing armor made of metal. On a hit, the target takes 1d4 lightning damage, the target then must make a CON saving throw vs. your spell DC and if it succeeds no further effect occurs and if it fails the target can't take reactions until the start of its next turn.

The spell's damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
