As an FYI Xur is selling Gjallarhorn (go to Strange Offers Tab) for 23 Strange Coins I don’t know if you need the 30th Anniversary Pack in order to pick it up at this time. Either way, it’s a Dungeon exotic and is one of the most iconic and fun weapons in the game. Plus 23 coins is very cheap. I’d highly recommend picking it up if you don’t have it! Worth giving it a shot on the off chance you can pick it up :)
