I ' m pretty new to giving advice on this so bear with me hereLinthia is an excellent farmable sub for Ronove , although it seems like you might have trouble obtaining her even in coop judging by what you listed in your box . Sitri is a very bad sub for Ronove I think Kushi is a better replacement for that slot . Definitely look for possible heartmaking subs as well . KaedeDkali are good ones , but aren ' t easy to get being 6 . Look out for farmable ones as well . I have a hypermax Ronove up in slot 1 , my ID is 314 , 899 , 331 IGN is MagiCat , send me a BF as well if you can ! <| sep |> Firearms has terrible scaling . Never go above enough to unlock talents ! That extra 1 k is barely pulling a 6 % increase when it could be a 35 % toughness increase . Damage sources are in many other places .
