PoE Impending Doom, Pathfinder builds

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!

More CDR from boots, or possibly belt? I'm farming sanctum for more relics, but they are just such tras

Thought Impending Doom was cool, but had a Pathfinder leveled, and wanted to try a different take on it with poison prolif. This is where the build ended up. By no means fully min/maxed, but it was very comfortable mapping, and despite the low HP, was incredibly tanky. Huge movespeed and DoT playstyle also makes it amazing for Sanctum. I've been experimenting with some other builds, so wanted to leave this here in case anyone wanted to try a PF version as well. TLDR: Curse immune, Full ailment immune, tons of recovery, permanent f
