Seriously, i'm trying cruci and I run into these and it just seems dumb?

I've got 9k life, capped magic resist, capped phys resist, 95 all resist, max block and this monster will straight up 1 shot me. Instantly. If there's one, I may get lucky and block enough hits to kill it but if there's a pack it's simply impossible. I can handle a pack of nilithanks if I play it carefully but these, there's nothing.

Nothing else in the game even hits close to as hard as these do, I feel like the damage is overtuned or something? There's 0 counterplay to this monster (apart from having a host hide in the corner while people spam die to kill them or being ranged and shooting/hiding). It's all well and good having stuff hit hard, but when a defensively maxed out character gets 1 shot there's something wrong...
