the craft of lvl 7 weapon is bug, i get all items to craft, but need oriharukon, and dont exist that. the icon is orhichalcum, and of that i have 80k... i get all the rest but dont let me craft the weapon

To craft weapons, you need Oriharukon, but you have 50k Orichalcum, their icons are almost identical.

What's the bug here? What's the name in your recipe book? If it's Oriharukon, then that's how it should be. If it's Orichalcum and can't craft it, then you need to fix the item in the client.

i was bug...now i see the rcp for craft. for lvl 7 weapon box, you have to create till you get the weapon you need?

Yes, you get a box from which you randomly get a weapon.
