You clench your hand in a grasping motion toward a creature within range, wrapping the target with twisting ribbons of shadow. The target must succeed on a Strength saving throw or be grappled for the duration, and you may choose to levitate the creature up to 3 feet off the ground. A creature grappled by this spell can use its action to make a Strength or Dexterity check (its choice) against your spell save DC. On a success, it frees itself.

If the target of this spell has attacked you or forced you to make a saving throw within the last minute and has never been damaged by you, it has disadvantage on its Strength saving throw. On a failure, you can choose for the target to take 1d8 necrotic damage as part of the casting of this spell, and an additional 1d8 necrotic damage at the beginning of each of its turns while grappled by this spell. The spell ends if the target is ever outside the spell’s range
