Build advice for Epilogue

I had posted about a build I was working on, and after tweaking I got to epilogue without much difficulty. Now I really need to edit it and change the gear and anything else to make it so the character can survive maps and higher level heists.

I reached the epilogue and now I am struggling a bit and looking for ways to improve gear, gem use, and possibly tweak skilltree for survivability.

Here is the build I was following advice from up until now:

I am now looking for ways to get the resistances to beyond 75%.


I am currently looking for how to find the crafting recipes to create 4 and 6 link gear.

Thank you for your help.
