General

Nx ratio is around 1:200-1:220 (In Windia, possibly similar) PSOK are 4k normally, 3k on sake, so I would not psok it for 30 mil. Lose way too much profit.

i will buy for 30m if you want =D

Uh clean fafnir dagger is 160 atk, you could 70% it and easily get 210 atk. Then comes the enhancement system :O.

10 mil, not worth the psok, can get better easily nowadays.
