Ring of Ineffable Evil
The wearer of this ring is constantly sheathed in an Unholy Aura effect. It bestows one negative level on any good creature that puts it on. The negative level remains as long as the ring is worn and disappears when the ring is removed. This negative level never results in actual level loss, but it cannot be overcome in any way (including Restoration spells) while the ring is worn.
