Ok so I'm in mooshu I finished all my the quest and I fought oin and everyone says that's the last to go to draygonsyphere and it doesn't show me nothing someone help me ?
We kind of need more information: What level are you? You defeated the Jade Oni and cured the Emperor? Did you check back with Headmaster Ambrose? My guess is you missed something or are not quite the right level. If you are really stuck and can't get help here, you can always email support and they will gladly help too. Good luck!
