...well, they're single slayer right now, still brown. But they have the title and slayer properties already so they should turn into double slayers. Anyways, what is the best way to deal with these and imbuing in order to get better bows? Is the best I can hope for to change their intial property to demon slayer then use gears to make them usuable and hope for some kind of elemental? Can they be imbued post-change?
