The Ring of Power is an UNCOMMONAccessory unlocked at Gemstone VI (6). 4 Gemstones (Ruby, Amethyst, Jade, and Amber) can be applied to the Ring of Power at the Gemstone Grinder next to Geo but each gemstone will only have half of the effect it would have on any other item. This accessory is a direct upgrade from the Talisman of Power and can be upgraded into the Artifact of Power.
