Blood Chain

You use the dark magic to cast out a blood-covered chain, tipped with a sharp hook. When casting, you can choose one target, within 60 feet of you. The target must succeed a dexterity save, higher that your Spell Save DC or be hooked by the chain. A hooked creature takes 2d6 piercing damage on contact, and 1d10 necrotic damage for every round the creature is hooked. The target is also restrained while hooked, and the only action they can take is attempting to free themself. Every round, you can reel in the target 15 ft with a bonus action, or 30 ft with a full action; on the targets turn, they can roll a constitution check with the DC as your Spell Save DC, on a success the target escapes the chain and takes 1d4 piercing damage. A target who is hooked, can still be attacked by other creatures and players. If the target is killed while hooked, the spell is dispelled.
