Got the build idea from Zizaran but since i'm on SC trade I made some tweaks to it. Using Stranglegrasp to grab all the totem notables & also Sovereignty so I don't have to spread out my tree too much & can run 3 auras comfortably. Instead I branched to EB so I can run malevolence with divine blessing. Also using Asenath's gentle touch for clearspeed & QoL in mapping. It's tanky af with Master surgeon + petrified blood combo (thanks to Palsteron for the idea), 3 elemental flasks & capped spell suppress. Once I am able to afford Progenesis I'll replace my silver flask with that & get onslaught from the totem medium cluster.

Tbh it exceeded all my expectations! It melts juiced invitations and pinnacle bosses in seconds. Mapping is not the fastest but still quite good & very smooth. Asenath's helps a lot especially in dense mobs like expedition. Fully charging crucible on t16 regardless of map mods.

You can also make it much tankier by taking out Dendrobate & replacing with a crafted rare with life, spell suppress & phys taken as. Then you'd run divergent herald of agony to cap out poison chance & drop some spell suppress on tree to grab the mana cluster for 12% reservation efficiency. This + enlighten 3 in helm should be able to run all 4 auras - haste, grace, petrified blood, HoAG. (assuming amulet has the sovereignty anoint).

I'm not good at build making at all so I'm sure there are tons of people who can make this build 10x better. But here's my path of building if anyone wants to take a peek

As you can see, the bossing dps is really good & very comfy playstyle. I'm terrible at boss mechanics so I die once to memory game and several times in Uber exarch fight. Pretty confident this can take down all ubers, but I'm not gonna respec my entire atlas to do that lol

Final PoB (lvl 100) - https://pobb.in/ej4lNGjsQPhM Added large thread of hope to save points, running Progenesis & dropped the silver flask to get onslaught from medium totem cluster. Also as suggested by another player who is running the same build, added a grace spell suppress + haste phasing watcher's eye. The phasing really helps when mapping. Total ~50div spent on the build now, and I'm probably not gonna push it any further. It can already do pretty much all content in the game.
