Curse of Chains

A black brand resembling iron shackles darkens the ankles and wrists of two creatures you can see within range that are within 30 feet of each other.  Both must make a Constitution saving throw.  A willing creature can choose to fail this saving throw.  On a failed save, a creature is cursed.  If only one creature is cursed in this way, you can use your action or bonus action on a subsequent turn to force another target that is within 30 feet of the cursed target to make the saving throw.  While two creatures are cursed by this spell, they are unable to willingly move further away from each other.

A remove curse spell, or similar magic, ends this curse early.
