You’ll start at the Ulduar Scrapyard teleporter. Use the teleport fro “Anthechamber of Ulduar” Now just walk to the boss in question. The boss You’re fighting is called “Algalon the Observer”. Take a right here. And another right here. And ANOTHER right here. You need to open the doors first. Use this console. And now for a bit of roleplay. Just follow Brann. Some lore : Algalon the Observer is constellar being who was charged by the titanic Pantheon to watch over Azeroth. The death of Loken (The Prime Designate of Azeroth) dispatched a singal to call Algalon so that he could scan Azeroth for “signs of corruption”. If the scan would indicate that Azeroth was corrupted and beyond saving, Algalon would initiate the “Re-origination protocol”, wiping all living creatures on Azeroth. It is the job of the raid to defeat Algalon so that he cannot send the signal for Re-origination. Enjoy some nice dialog about what I said earlier. And the scanning begins. Algalon is yellow to You, but You can still attack him. Now all that’s left is to just kill the boss. Enjoy Your Astral Walker title ! (Especially if You’re a shaman :)) In the chest You’ll get the Reply Code which You can take to Dalaran and use so that The Pantheon won’t Re-originate Azeroth. Thanks for watching !
