It that hates enemy OP

I got one shot by the it that hates breach enemy, a white mob variant, not even a rare.
Its multi shot attack can hit you off screen. Its chest lazer also one shot me in a subsequent map.
I could understand if this was a rare variant with lots of mods, but no, the trash version has more damage than most Uber bosses. I had to watch my footage back to make sure I wasn't imagining things.
Please look into this enemies damage. Not even the rare abyss mobs were dealing this much. One shot by a white mob, something is extremely broken.

Ye i can confirm something is off with them, i once got killed twice by the same white mob, nothing else on the map was even close to the damage it had.

I swear there’s some fucked-up shit going on with the mobs. I’m sitting at 2100 HP and 4.4k mana (can overflow to 6600 mana with 88% damage taken from mana before life). I can literally face-tank the Citadel boss on the highest difficulty, yet I just got one-shot twice in a row by white mobs—dead from a single hit. White mobs should never be able to deal that much damage.

At first, I thought there might be some mechanic that bypasses my mana. But after those two back-to-back one-shots, I’m really starting to doubt that explanation. I’ve also noticed that it usually happens when I get hit by some kind of projectile.

On top of that, I’m maxed on all resistances (75% all elemental and chaos resist), and I’m always inside my Oasis: ~6x% damage recouped as life, ~5x% damage recouped as mana, and about 900 mana regen per second.
