PoE builds similar to [POE] 3.21 Crucible Impending Doom Pathfinder Map/Boss Showcase

POB: I've sunk a good chunk of change into my Impending Doom PF and finally was able to beat the pinnacle bosses but not with out a struggle (mostly mechanics and dot's). I want to try and make a push for Ubers but clearly right now I dont have the required DPS but I am stuck on how to get there. I've seen steelmage melt Ubers.. is it only possible with god tier gear? Any help or advice would be appreciated. Thanks!

On ssf standard. Wondering if i should create a build around both of these or drop one. Most people I saw on ninja were only running one or the other. If I run both i am thinking about putting an aura set up in staff for lvl 7 enlighten. With both I hit dot cap rather easily, but I might struggle with defences a bit. I want this to be a bosser. So mainly wondering how i fit in more defence. Main things i can think of is purity watchers eye and progenesis. POB (Just something I threw together quickly, needs a few more things) &x200B;

Looking to find some suggestions on any tech or suggestions to improve my build? I've done pretty much all content comfortably. I have spent a lot of time in PoB trying out various things, but I think I am at the peak of what I can get. Only thing I have left to do is get -% res on wither for belt enchant. Just wondering if anyone has any suggestions on what to improve or where to go from here? Thanks
