Blood Chain Of Tethering

A beam of sickly, red energy lances out toward a creature within range, forming a sustained tether made out of blood spikes between you and the target. Make a ranged spell attack against that creature. On a hit, the target takes 1d12 magical piercing damage, and on each of your turns for the duration, you can use your action to deal 1d12 magical piercing damage to the target automatically. The spell ends if you use your action to do anything else. The spell also ends if the target is ever outside the spell’s range or if it has total cover from you. However if the target breaks the spell connection, the target then must make a Constitution saving throw. On a failed save, the target takes 1d6  psychic Damage, and it has disadvantage on the next weapon attack roll it makes before the end of its next turn.
