Zalmarath, The Colossus glitchy one shot (HC experience ruined)

Zalmarath, The Colossus will randomly one shot you in a not intended way.

Video contains example. I think it usually happens during dagger slide but not 100% sure.

Time: 1:17

same thing happened to me, I have the vid saved, I have 700 HP, the dagger slide hits me once for 100 damage and then a second hit with no visual indicator one shots the rest of my health

Yup happened to me too

I'll add to this as it's my 3rd death to this boss.

My level 26 to zone level 22
250 armor (not that it would help much)
hitbox nowhere near me
Over 860hp in 1 hit

Another death: https://streamable.com/k69gap

This is number 4. I'm hardstuck lol

Happened to me as well on HC. I had already killed this boss, but went back to kill it again to try to get "The Trail of Corruption" quest to progress, since it seemed stuck.

I have about 900 HP at level 31, and none of the other attacks take me below 75% HP, but if he touches me with the sliding dagger it's a 1 shot. This isn't really a telegraphed or wind-up attack, so it seems this is a bug or poorly tuned.

Bug report is from a bit after the video ends.

Same glitchy one shot, killed me in HC, this is me trying to figure out wtf happened in softcore afterwords.

Actual 1 shots from 1000 hp, while nothing else he does hurts anywhere near as much.

Makes me want to stop playing HC :-(

His dagger-slide attack divides the arena into 2 areas - one smaller and one bigger. It looks like standing in the smaller one makes you dead.

ya HC rip from this here too, and the game client hang/ripped me in POE 1 as well. May have to give up on HC.

I have the same problem.
The boss killed me with one hit, although according to the visuals it didn't even hit. And this attack didn't do much damage.
