Black Lash

You create a whip of dark energy that tries to grip a creature that you can see in range. Make a ranged spell attack against the target. On a hit, the target takes 2d8 necrotic damage and the whip grabs the creature. A target must make a Strenght or Dexterity saving throw. The target takes 1d8 necrotic damage on a failed save and are grabed, or half as much damage on a successful one and its not grabed by the black whip.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, one additional whip leaps from the first target to another target for each slot level above 5th.
