Water orb drowned city

So I was farming with 53 lvl, 2,5k life and 50% resists and got oneshotted while standing like half sec in water orb or whatever that thing is. No indicator of any hit or whatever that would harm you. Is that like, common? Because I did like 5 runs and I was standing alot longer in multiple orbs and it never happened. What exactly I was oneshotted from if there is no indicator of a hit. I thought its only degen. And how is it possible that I took so much damage that I couldn't tank a white mob normal hit? I could tank pretty much everything up to that point including monkey when I was way lower lvl.
So is that a bug or am I just missing something?
As I said it was a single monster and I was standing in in for like half sec, no burst damage, just dropped death from one single I dont even know what.
Thank you

it's a drowning orb, not a bug. if you stand in it for a short time you insta die. its's not degen, it's a one shot. if you played poe 1, the eater of the world and a tier 17 mod has the same orbs.

Yea but is it really good mechanic to let people die on random white monster, while I don't have any problem during bosses? That's what was wrong with poe 1 that you could be killed by random white mob while could stand in boss arena afking. I get it that poe 2 is harder and I love it, but then what is the point of making tanky character that could tank bosses but not normal monsters
99% of players dont know about this and can't focus on looking all around the screen to see the debuffs while dodging and atacking. And like I said, I did the area 5 times and this was in a blink of an eye. It was nearly instant, the monster did the orb and I hit spacebar in around half sec and got killed. Thats why I report it as a bug

you get slowed down drastically by the orb, so if you are near or in the center of the orb, a dodge roll will not help you.
yeah most people learn the hard way, myself included. i got pushed into the orb by monsters attacking and then blocking me, there was nothing i could do. also a problem is that sometimes you cannot see them well, the contrast to the colors of the map is not very great. or the mobs spawns the orb right on top of you.
i agree, i don't like these kinds of one shot mechanics early in the game, but i think they are fine in a boss fight or a t17 map.

Exactly, like I know it's a EA and alot of things are just a tryouts but this isnt exactly for good of the game because it demotivates you to actually build around defences and health etc
I get that HC is about learning from failure, which I do. But at that point in the game you don't expect to go farm area 13lvl lower just to get random oneshotted
