I think the Fourth Dance on a kaguya could be bugged. When I first got it, i killed my multikey and suddenly leveld up, when i had just lvld. Then when i was fighting mclovin, i just lvled up and killed him with it and i lvld again.

You can Multi Village/Clan by doing something similiar to how you use to be able to do it.

Edit- I just found another way so there is 2 ways to multi village/clan.
