Shouldn't you scroll the one with the best clean atk?

are you planning to go all the way with your db funding wise?
things to consider: fearless cant be transposed to sw, fafnir can, if you plan to not go sw, ignore the little voice in your head because you will end up going sw katara no matter what anyways (assuming you can afford one)

SW katara is the best sw weapon in the entire game and if your going to main a db your going to end up with one. Fafnir would be better since you can transpose it, unlike a fearless katara. However, that being said you should go for an EMP katara since its the cheapest katara you can transpose to an sw.

Im kind of in a similar situation because I want to be able to trade my items (especially a weapon) when Im either done with the character or quitting the game.
