(Cruel)Shadow Minion one-hit RIPs | 1,6k life Hi-Resistant Character

I died in nemesis. GGG's fault. Developers, pls fix.

I was just spinning around with cyclone at Vaal, having almost full life, no problem.
Suddenly the "Vaal Oversoul" raises his huge sledge as if preparing for his massive groundslam.
I casually decide to begin spinning towards his backside, since the buildup animation for the groundslam is so incredibly long I don't suspect any trouble.
But then suddenly at the point that Vaal has managed to raise the sledge almost behind his "head"(This means that there's still at least another second before the attack is supposed to trigger) I instantly die.
Desync is most likely not the case as I've been having perfectly good connection with little to no desync all day.

This was on nemesis, so I'm stuck in standard with what I thought would become the pride of my account.

I constantly keep an eye on my health bar, it's kindof an obsession, and the last time I glanced at it, it was ~1350.


Creatures that were currently alive and kicking in the zone were Vaal Oversoul, a Vaal Fallen and a shadow minion.

The Vaal Fallen was meters away and currently heading towards my character, so it wasn't him who hit me.
