Insignia determine what prefix, and thus attributes, armor will be crafted with. Intricate gossamer insignia produce armor in Exotic quality, and their recipes must be purchased from a master craftsman.
The generic recipe for crafting an intricate gossamer insignia is:
|Intricate Gossamer Insignia||= 5 Gossamer Patch||+ 5 Glob of Ectoplasm||+ 5 Fine Crafting Material|
The recipe sheets for Celestial, Commander's, Crusader, Diviner's, Marauder, Minstrel's, Trailblazer's, Vigilant, Viper's, Wanderer's, and Zealot's are purchased from certain vendors. In addition, Celestial, Giver's, and Zealot's recipe sheets can also be bought from the Trading Post.
Cavalier's, Dire, Magi's, Rabid, Sentinel's, Shaman's, and Soldier's insignias are only available by salvaging Exotic armor with matching stats. Black Lion Salvage Kits have a 50% chance to retrieve an Insignia.
