Fi/Br no katana?

so im a fighter with a subclass as a braver but for some reason im unable to use a katana or a bow, what am i missing, can someone explain?

It needs to be Fi equippable version of said weapons. Mostly weapons are main class only, but some weapons have other classes or all classes on the 2nd tab of item info.

so where should i farm for a katana? ive been looking an nothing has been coming?

@FunkyXHunter They randomly drop during quest based on what you have equipped. I wold run some advance quest for a better chance.

You can also use friendly ALL class weapons, like the sigma weapons. They sell for around 20k,30k and you'll be able to run PA from it.
