Everything goes dark, the only sounds are the hollow screams of two souls joined by a single red thread.
You create a link with a creature you can see, make a ranged spell attack to hit. On a hit the target must make a CHA saving throw or be bound to the tether. On a save the target takes 4d12 necrotic damage but the link is not made. On a failed save a tether is made between the target and the caster, and both are frozen in a trance so neither can move or take any actions. On the first round and each subsequent round, the target takes 2d12 necrotic damage. The target may make a CHA save on their turn to break the tether. If the tether is broken the caster takes a d6 damage for every round the tether lasted. If the tether is maintained for the full 5 rounds, the target instantly drops to 0HP and is considered dead.
