The original 2nd Edition entry from the Forge.

The Master Ring is a simple artifact if there ever where one. The Master Ring when worn, allows a being to employ up to nine other magical rings, one for each finger. It warps the laws of magic allowing a being to exceed the limit of two (one per hand) rings. It has no other powers.

The Master Ring is a simple artifact if there ever where one. This ring appears and functions exactly like a ring of invisibility. This power pales in comparison to the rings true power. The Master ring has the ability to defy the laws of magic itself. The one Ring when worn, allows a creature to employ up to nine other magical rings, one for each finger. The ring has a warping sickness upon those around it. Anyone who knows or even suspects the powers of the ring become deeply jealous. They must make a Will save (DC 10) whenever they are exposed to its presence or be driven to take the ring from its current owner.
