those items will be in the new expansion if they release the "satanism" part of the expansion. the whole idea behind it is that you need to kill special bosses in order to get certain craft materials. you then take the materials to a chaotic generator thingy and make the items but i can't tell if its random or if you can select which item to get by having the right combination of items. i could be wrong though since the translation program i got can only translate about 60% of the page off of the koko main site.but liek i said i doubt those items will be in expansion. they are way to overpowered and good. there would be no use for other weapons if you could use those.[/b]
a lot of ppl said that some of the eslant dungeon items would be too overpowering at first too and you also have to remember that just because you have good items, doesn't mean you know how to use them.
