Ring of Dominion

A ring that draws out the potential of the wearer beyond his or her limits. It was forged by a visionary green mage who devoted her life to its creation by using three different types of precious stones yielded from creating new spells and items. However, the alarmingly quick rate in which it amplifies the wearer's abilities upon equipping it made it an unnerving accessory for anyone to own. Thus, rumor has it that the green mage sealed its manufacturing method away along with herself.
