Getting Cloudy Sword - Yamataikoku

I needed that sword on my alts, because i just started leveling human pets. They are lvl 34 and they are dying in every training spot. Especially Niss - she didnt add even 1 point on con. XD.
So after they reach lvl 34 (wich was needed for her trainign spot) we take Belly chain neclaces and these cloudy swords with 300 hp to make them survive in training.
Level you need to reach for that sword is 30.

To start the quest you need to go the the building wich has guards on the door and talk with woman named Himiko.


She will send you to sky world or something like this. There need to go to left and will spawn to another map. Where you put the sake wich Himiko gives.
And 8 headed snake will appear. Fight is kind of hard. With a lot of seal. Only the boss dont seal. But he has decent atk and matk. 39k hp and lvl 165.
Reward is the sword + 5% xp capsule
