The Helm of the Noble (Helm of the Noble +1 in-game), also known as Helm of Glory, is an enchanted helmet. Aside from protecting the wearer from critical hits, it raises charisma by 1 point and provides a -1 bonus to armor class.
Helm of glory: 'Helm of the Noble.' Named for its original owner, Sir Tain the Noble, this helmet saw many great battles in his possession. It was eventually passed to Sir Tain's squire, who had served him faithfully for almost ten years. Alas, the young man had neither the strength, nor the skill to uphold his master's legacy. It is rumored he lost his life of a worthy, but ultimately futile cause, and the helm has had many owners since.
