In-game description
"Bracers of Defense AC 4 Sometimes known as Gauntlets of Chain Mail, these bracers were first worn by Tapid Gornoak. He was still an active warrior at the age of seventy-five but the weight of his armor was getting harder and harder to bear. A companion, the sorceress Nadalarin, created these bracers for him. She also cast a permanent illusion over him so that his men would think he still wore his heavy chain. Tapid died twenty years later, his hands wrapped around the neck of an orc chief when old age took him."
