The Architect

I keep dying to this dude, and it seems very hard to avoid all the stuff going on in that room. I was doing around tier 8-10 waystones and everything seems fine, and I do not die much at all to anything else as I play pretty careful.

But 2 times I get to architect and I get 1 chance to learn the fight, then I am thrown out of the temple and need to wait another 6 maps or more before I can try again. I am afraid I need to have a build that can oneshot him to have a chance, is that intended?

Since I play ssf, that is harder to achieve aswell.
