Smithing ring

The Smithing ring is made by right-clicking the uncharged ring and selecting "Charge" within the Smithing skill plot area of the clan citadel, which requires a tier 3 citadel. It gives 150% Smithing experience until you have gained a certain amount of experience, determined by your level and the tier of the Smithing plot, after which it crumbles to dust. A new uncharged ring can only be obtained after this one has been used up.

The ring does stack with Goldsmith gauntlets, yielding 84.3 experience per gold ore.

The ring does not work in blast furnace.

It also should be noted that the ring does not work when crafting gold or silver bars into items, as these activities do not use the smithing skill.
