Overtuned breach enemy

I am not sure what enemy it is, as im constantly buried in breach enemies, the breach guy with two tails that shoots projectiles across the ground is killing me instantly through 6000+ hit points. Max resistances. Normally I just assume its the way the game works, but a normal enemy should in no case, be killing me faster than pinnacle bosses. The guy doesn't even have to be rare or uncommon. Just the normal white bar is killing 100× faster than xesht
