Blood Binding

You send your chains snaking towards a target within range, imbuing them with the power of your blood magic. The chains wrap around the enemy, constricting like serpents and holding them in place. The target must succeed on a Strength saving throw or be restrained for the duration. While restrained in this way, the target takes 1d8 necrotic damage at the start of each of its turns. The target can make another Strength saving throw at the end of each of its turns, ending the effect on itself on a success.
