Commander's ring

A commander's ring is a magic +2 ring that is made by the War Wizards of Cormyr for their military commanders. Three times a day each, the ring can produce the effects of daylight, feather fall, knock and wall of force, but only when the correct command word is uttered. If a purple dragon ring is worn on the same hand as this ring, they are treated as one ring. The wearer is able to detect any purple dragon rings within 100 feet (30m), but this power of detection is blocked by stone, metal, wood or other solid boundaries. These rings are worth around 120,000 gold pieces each.

In the Year of the Ageless One (1479 DR), Royal Magician Ganrahast Aeiulvana, Lord Warder Vainrence, former Royal Magician Vangerdahast Aeiulvana, and Storm Silverhand found a way to enchant the rings to safely allow telepathic communication through the team and commander's rings, a feat previously impossible due to the aftereffects of the Spellplague.
