The bands come into two parts, a collar and bracelet; both collar and bracelet are marked to match a set, one master and the other the slave. Subjugation bands are magically linked to allowing the bracelet wearer . If the collar is placed around someone's neck, they are unable to remove it themselves and become incapacitated if they try. The collar part of the Band of Subjugation will continue to tighten if external forces try to remove the collar resulting in strangulation failsafe (after 5 mins of inactivity the collar will loosen)
While both the collar and bracelet are being worn, the owner of the Bracelet can:
Decide the fate of the wearer by end the life of the collar wearer
Choose to Restrict any magic the caster may use
Talk telepathically with the collar wearer
Each wearer can determine the location of the other so long as both occupy the same plane - The range is 500miles after leaving that range the link is broken and the collar fail safe will activate.
A creature, including the one restrained, can use an action to make a DC 25 Strength check to break the Subjugation band. On a success, the item is destroyed, and the creature is freed. If the check fails, any further attempts made by that creature automatically fail until 24 hours have elapsed.
Once the bands are removed they are destroyed unless the correct paired bracelet of subjugation is used
History - The bands of Subjugation hail from the plain of Mirrodin, created by 'Memnarch' to subdue an army and used as weapon against the heros off that war, Glissa, Slobad the goblin, Bosh Iron golem and keeping 'Karn, the great creator' at bay .. lost after the destruction of Mirrodin and scattered through the planes over the ensuing decades.
