Signet Ring of the Bronze Dragonflight

 is one of three series of epic rings that are given as faction rewards by the Brood of Nozdormu faction. This inital ring may be switched for another ring of a different "path" by completing a quest once you are Exalted with the Brood; this was added by Blizzard since it's a common mistake to chose the wrong "path". Each ring confers different effects on the wearer depending on its "path", which can be determined by its inscription:


 * "The Path of the Conqueror"
 * Signet Ring of the Bronze Dragonflight (Conqueror, Neutral)
 * Signet Ring of the Bronze Dragonflight (Conqueror, Friendly)
 * Signet Ring of the Bronze Dragonflight (Conqueror, Honored)
 * Signet Ring of the Bronze Dragonflight (Conqueror, Revered)
 * Signet Ring of the Bronze Dragonflight (Conqueror, Exalted)
 * "The Path of the Invoker"
 * Signet Ring of the Bronze Dragonflight (Invoker, Neutral)
 * Signet Ring of the Bronze Dragonflight (Invoker, Friendly)
 * Signet Ring of the Bronze Dragonflight (Invoker, Honored)
 * Signet Ring of the Bronze Dragonflight (Invoker, Revered)
 * Signet Ring of the Bronze Dragonflight (Invoker, Exalted)
 * "The Path of the Protector"
 * Signet Ring of the Bronze Dragonflight (Protector, Neutral)
 * Signet Ring of the Bronze Dragonflight (Protector, Friendly)
 * Signet Ring of the Bronze Dragonflight (Protector, Honored)
 * Signet Ring of the Bronze Dragonflight (Protector, Revered)
 * Signet Ring of the Bronze Dragonflight (Protector, Exalted)

The first Signet Ring is given as a faction reward by Anachronos at the entrance to the Caverns of Time in. As your reputation with the faction increases, Anachronos will upgrade your ring to a better quality. You must be at least with the Brood of Nozdormu to receive the first ring, with upgrades for each reputation level up to Exalted. Each step-up also awards 250 reputation.
