well in the tree of life you go and fight the death oni and then after you do that you go and fight jade oni which is the last boss in mooshu and THEN you go into dragonspyre after you fight cyrus (the myth teacher)
How do you get to the tree of life? And is tree of life the dungeon with the last boss to pass MooShu and get to Dragonspyre, Jade Oni. Lastly, is the badge "Oni Slayer" the last mooshu badge?
