Beat the game without resting at a bonfire. The ring is given to the player at the conclusion of the credits.
Whilst this ring is equipped, weapons in the player's right hand become invisible. It is the counterpart of the Illusory Ring of a Conqueror.
By using soul giving items to get one million souls, one can instantly pass the door at the Shrine of Winter and go to Drangleic Castle at the start of the game. This saves the player a lot of work, as only seven bosses will be required to beat the game.
A relatively easy way to acquire this ring, for magic users, is to wait until the first New Game Plus cycle to attempt the run. Prior to passing into NG+, attune Repair, any variant of Heal, and any other magic one desires, then wear the Crown of the Old Iron King to restore casts. Repair and Heal removes the two most common needs to rest at a bonfire, making the challenge a matter of patience.
