Katana/Bio help needed

[Subject 22J2]

So far all of my experience has been below level 50 with no dips into or understanding of how IO sets work or how to slot them with any effectiveness. I have taken a few stabs at trying to do a build in Pines and it rapidly becomes clear that I have no idea what I am doing.

 

So what should I do for a Katana/Bio build? Where should slots go with sets in mind? What sets should be in mind even? I solo a lot with some grouping for TFs. I would like a build that can continue this trend and is able to do well both soloing (TFs ideally) and grouping... Mostly I am at a loss.
