Please don't play this build. It suffers from 3 big issues.

1. You don't really have a way around 60% inc damage taken and wardloop is already weak to big hits
2. You have a few seconds after losing temp chains (by getting cursed by a strongbox, a mob that applies it or Hexer) to re-self-curse yourself with temp chains before your olroth's runs out and you nuke yourself into orbit. You can see in the video I actually have Anger socketed as a panic button since that reserves all my mana and lets me stop the wardloop but it's not a good playstyle to have to constantly check your curse status. I died a lot this way
3. You need to wait 40 or so seconds at the start of each map to fully stack all the debuffs from Glorious Madness. If you don't you run the risk of dying if the reduced flask effect is outstripped by the reduced life/es recovery and increased damage taken debuffs. Additionally, the reduced flask effect seems to have a delayed application so in practice it's probably more like 1 minute's worth of waiting to get your ward to a point where you can loop.

Core concept of the build was to leverage the reduced flask effect to crank permanent ward for wardloop. Unfortunately, we lose ward on boots since Beacon of Madness is a boot. We can still get quite a lot of ward this way but while our life recoup is still okay for medium degens our 2.56k ward is a paper tiger since 60% inc makes us extremely zhp. It does mean that the build can run some chaos res (in fact I need more chaos res since you can see my health pool is dipping every time I loop) or phys mitigation but you're still squishy af.

All in all, the build was way more fun to think about than it was to play but I'm still glad I did it because it used some really obscure tech to function (ward loop is still cool, an actual application of divergent cold to fire, reduced aoe self curse and obviously trying to make beacon of madness' have more upside).

The build can do reds but not really with wrath of cosmos and you're constantly on tenderhooks because you need to have that self-curse ready to go again if you hit a hexer mob or something. I took this build to lvl 88 and gave up and got a 5way because it was so painful to level.
