Big green balls in heist?

So i just got wiped like 10 times in a labs heist blueprint buy getting hit by big green balls.
Of course i didn't get out and lost what i reckon was a few ex worth of loot.
Anyway WTF are they? i suspect chaos damage but how the hell do you get past them?
Thought my freezing pulse char was pretty strong (standard)

It's chaos indeed. With higher res you won't feel them, damage isn't overtuned. In a difference of red balls of death, and blue ones to a lesser extent.

Thanks for that, maybe just use an Atziri's flask if i get them again?
