So I continued playing quite some time ago and recently decided to see whats new and to keep working on what I have. My current weapons are as follow: http://imgur.com/a/zVCPA
I used to farm on Vanaduke before stopping, the set I was building was around that (5* Black kat and mixmaster, 5* Seerus mask, Volcanic plate shield and Blitz as well as Shiver), but I dont know if its worth to keep working on those since they're all UV'd and done or if I should start something new.
My playstyle is basically sword + gun + bomb or just one or two of those in any combination, use a lot of charged hits on blitz for those pesky zombies, crowd control from afar when needed with guns and bombs but also have everything else because why not.
Which weapon skin should I go for next? Thanks in advance.
I think you've milked the 5-star items for all they're worth. So now is a good time to start working on 6-star items. They're not a big improvement over 5-star, but they get you ready for 7-star, which is big. Of course, finding the Nuclear Fire Crystals is a pain, but that's what depth 38 is for.
