(PoE 2) Act one final boss

So i am now stuck on the final boss of act 1 not because it is almost impossible to live past the move were in second phase he summons clouds and a circle in the middle, then you have to dodge him as he goes through the circle, would be a cool move and not that annoying; but when i am also being attacked by 30 monsters at the same time pushing me every where and surrounding me to a point were i cant move so i either die by the boss or by them, it gets annoying. so for a suggestion, either please get rid of the mobs during that move or reduce it to a point were i cant get as easily pinned and can manage it.
