Got bored with the MF meta really fast and wanted to make a fun build using Stasis Prison since it was so accessible this league. Ended up getting super lucky on crafting gear for it and finding items (amazing the watcher's eye even existed), and had a blast pushing it to the limit.

Uber Uber Elder kill: https://youtu.be/6s0G-4NbDmY

Pros:

• Uber Uber Elder (and some other bosses) are trivial
• Easy dot cap (36m dps) due to high cast speed and 15 proj/cast with 45% inc AoE
• Super tanky with over 100k ehp due to:
  • 100% lightning/cold taken as fire/chaos (can disregard lightning/cold altogether)
  • 88% Fire res/87% Chaos res
  • 40% less fire damage taken (Dying sun with >100% flask effect), 6% reduced ele taken from Lunaris
  • 50% of life loss from hits taken over 4 seconds (ignored due to sustain) from Progenesis (w/flask effect)
  • 44% Phys hits taken as Fire/Chaos and decent Phys reduction from 4 endurance charges + Adrenaline + Pantheon (can also swap in granite/taste of hate for shenanigans)
  • Chaos dots heal, including Flame-touched from boots for adrenaline due chaos conversion and flask leech for 100% leech uptime
• Insane sustain via 144% recoup to the point that only 1-shots can kill it (in most cases, see cons)
• Easy Ubers/Valdos
• Decent mapping due to 166% MS, PF poison prolif, many proj/high AoE

Cons:

• Can't do things that turn off flasks, like some map mods, torment spirits, and ultimatum mod
• Can die to things that decrease recovery (map mod, Sirus geysers though still doable) or turn it off (Maven though still doable)
• Can die to Nasty mod combos in Simulacrum/Cortex due to high physical hits combined with overwhelm and -max res (though still doable)
• Cost: yes
