So, what is the furthest you have gotten without dying on softcore or hardcore?
For me it was normal Belial, I made the mistake on my monk of trying to nuke him down fast rather than taking my time and avoiding everything I could. Second attempt went a lot smoother and I stayed around 50% health and above. :PAfter that I have died a fair few times in act 3 due to overpulling and rookie mistakes.
I'm planning on having a go at hardcore when I complete a normal clear with little to no deaths.
