Crimson Chain

You unleash a chain of blood-forged necrotic energy that lashes out and binds a creature within range, embodying your merciless control over blood and power. Make a ranged spell attack against one creature.

On a hit, the target takes 4d8 necrotic damage as the chain tears at their life essence. At the start of each of the target's turns for the duration, they take an additional 2d6 necrotic damage as the chain tightens, draining their vitality.

The target must succeed on a Constitution saving throw  at the end of each of their turns or be restrained until the start of your next turn, trapped by the relentless force of the blood chain.
