Vor'Gamen's Chained Hands

You throw the severed hand of a humanoid at a creature within range. Make a ranged spell attack. On a hit, the hand grasps the creature and a spectral chain appears, attaching the hand to a post on the ground at the creature's feet. For the duration, the creature's speed is reduced to 0 and it is restrained. On subsequent turns, while you are maintaining concentration on this spell, you can use an action to make another ranged spell attack at another creature within 10 feet of the original target. On a hit the new creature is chained to the first and cannot move more than 10 feet from it.

A chained creature can use its action to make a strength saving throw to escape the chains.
