[POE 3.19] Low-Life Cold DOTs Occultist (all Uber Bosses, 9mil DOT DPS, tanky, 90% all ele res)

Uber Boss vs Map Setup I removed my medium clusters because those gives me ES regen on kill (and DPS of course) but it doesn't help during Uber boss fights so I respec those points into ES regen and lethe shade. I took Growth and Decay (with 10% reduced DOT mastery) instead of Snowforged for Uber Sirus fight, it helps. Why Lethe Shade and ES Regen? Uber bosses has tons of degen skills (except searing exarch). Speccing into ES regen and lethe shade makes a huge difference. I failed Sirus twice before switching fully to this setup. WIll this make Uber Bosses easy? No. It makes Uber Bosses "possible". I failed Uber Uber Elder once. The easiest fight for me was Eater of World, hardest was Uber Uber Elder. You may find it easier if you have better skill than me! Bonechill vs culling strike on Creeping Frost I have not got culling strike on gear or jewels so had to rely on support gem swap. Only swap to culling strike when within culling range (<10% life) Flasks I used Sapphire for Uber Uber Elder, Ruby for searing exarch. For other fights, can do with usual basalt flask. +2 Wand vs my wand Most will recommend using +2 (+1 spell and +1 cold) wand for more DPS but it's actually not that much more. Based on my current tree and gear, a typical +2 wand is about 3% more DPS but it'll cost at least 30D more to craft so I'd rather spend it elsewhere. Why do you die so much fightning Uber Bosses? It's my first time doing Uber Bosses, did not attempt them in 3.18 because I was doing SSF. I did not spec into lethe shade and ES regen until Uber Sirus and Elder. I honestly thought 90% all elemental res and Armour is enough to survive them. I was wrong! Budget +4 Shav = 80D Aegis Aurora = 15D Crown (with corrupt + enchant) = 5D Wand (self craft) = 5D Glove (including implicits) = 2/3D Boots (including implicits) = 2/3D Rings (unset ring was crafted) = 1D each Crystal Belt (self craft) = 5D Amulet = 1D Watcher Eyes = 12D Melding = 4D Impossible Escape = 12D Other Jewels (total) = 8D Total Cost = 155D Must I spend that much to kill Uber Boss?? No. You can do it with a +2 Shav but it'll be slower and riskier. That will bring the cost down by 70D. Should I use this setup for mapping as well? I don't recommend it because you can easily spec into profane bloom by dropping malediction and clear so much faster, you'll have enough DPS anyway.
