Some Rare Monsters one-shot no matter what

Although I am not exactly sure why, some rare monsters one-shot regardless of resistance, es, life. While everything is going great, suddenly eating one at a very irrelevant point is really annoying and the experience loss seriously affects the game.

This usually occurs on maps with Corruption or creatures with chaos modifiers. I am not dying as a result of a decrease in time or being hit a few times, I am talking about dying from 4k health all of a sudden. Fire, Lightning, Cold and Chaos my all resistance are capped at 75%. I have 2.5k energy shield and 1650 health. I have 78% evasion but I still get one-shot for no reason. And there is a strange consecutive explosion sound in all of them for which I do not know the reason. It gives me the feeling of reflect damage like in POE1.

I think this is a bug that needs to be investigated.

This issue comes from Path of Exile I and I'm pretty sure they won't fix it. For years we've been dying to one shot skills and they don't even care.
I was hoping they would fix it in Poe II, but since they barely launch updates, we should probably go to another game.
