Hello.
If you are a GGG employee, please stop reading here. I am not having fun. Goodbye.

Have they all left?
OK
There is a recently discovered interaction involving a modifier you can only get in this league: Reduced effect of non-damaging ailments. This allows your self-inflicted ailments to have negative effect on you. This is similar to Winterweave's reverse chill, but it is much more potent, because it can reverse the effect of Shock and Freeze as well.
Whether by GGG fun detection or by the end of Scourge League, this build will soon no longer be possible. But for now, it is possible. And it is glorious.
I will now show a short video demonstration: https://www.youtube.com/watch?v=L8PWfNuh6zw
Here is the PoB of the character I used in the above demonstration: https://pastebin.com/tH9qn8M2
