Dragon's Shadow Strike

You conjure a dragon-shaped shadow that streaks from your hand towards a target within range. Choose one creature you can see within 90 feet. The target must make a Dexterity saving throw. On a failed save, the target takes 6d6 necrotic damage and the shadow clings to it, obscuring its vision and movements for 1 minute. On a successful save, the target takes half as much damage and the shadow does not cling to it.

While the shadow clings to the target, the following effects occur: The target is blinded. The target is restrained. The target takes 2d6 necrotic damage at the start of each of its turns. The target can make a Dexterity saving throw at the end of each of its turns, ending the effect on itself on a success.
