Blood Bind

Choose a creature that you can see within range. The target must succeed on a Strength saving throw, or be restrained by barbed chains, taking 2d10 piercing damage and 4d10 necrotic damage. If the target is a construct or undead, they do not take the necrotic damage. You heal for half the necrotic damage dealt. At the start of the targets turn, they take 4d10 necrotic damage and you heal half of the necrotic damage dealt. At the end of each of the targets turns they can make a Strength saving throw to become unrestrained.
