Make a ranged spell attack. On hit, the target takes 1d8 necrotic damage and can't regain hit points until the start of your next turn.
If you hit an undead target, it also has disadvantage on attack rolls against you until the end of your next turn.
This spell's damage increases by 1d8 when you reach 5th, 11th, and 17th level.
