You fire a small bolt of dark energy towards a target that you can see within range. Make a ranged spell attack against the target. On a hit, you deal 1d8 necrotic damage and the target's AC is reduced by 2 against the next attack roll against the target before the end of your next turn.

The spell’s damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), 17th level (4d8).
