Chains of darkness

A dark chain flies out from the ground and attaches itself to a target creature. The creature makes a dexterity saving throw or the chain grapples the creature and deals 1d6 necrotic damage. Creatures affected in this way can make a strength saving throw at the end of each of their turns to break all chains attached to them in this way. Upon a failed save, the creature suffers an additional 1d6 necrotic damage for each chain still attached.

If cast as second level or higher add one chain that deals 1d6 necrotic damage per spell level above 1. If two or more chains are attached to the same creature the target is restrained.
