Divine Shackles

You attempt to fetter a creature within range with spectral bindings, forcing it to make a Wisdom saving throw. On a failed save, the creature takes 3d10 radiant damage (if you are good or neutral) or 3d10 necrotic damage (if you are evil), and is tethered to you for the spell’s duration. On a successful save, the creature takes half as much damage and isn’t tethered. A tethered creature cannot teleport or move more than 30 feet away from you. At the end of each of its turns, a tethered creature can reroll its saving throw, ending the effects on a successful save.

While a creature is tethered, you can use your action on subsequent turns to automatically deal 3d10 radiant or necrotic damage to the tethered creature.
