Tendrils of black mist extend from your fingertips, latching onto a creature and draining its vitality. Choose a creature you can see within range to make a Dexterity saving throw. On a failed save, the target takes 2d6 necrotic damage and is cursed for up to one minute. On a successful save, the target takes half as much damage and is not cursed. While the target is cursed, you can use your action to deal 1d6 necrotic damage to it automatically. The curse ends early if you use your action to do anything else, if the target is ever outside the spell’s range, or if the target has total cover from you. A remove curse spell also ends this curse.
