----------------------------------------------
That said, in Act I, I could do what I wanted, which was Sparkflint (+13% damage) and Magic Weapon (+15% damage), where damage was more like 40,000. Act 2 is/was/will be a 1-shot festival with that build.
I'd say everything is optional except Diamond Skin, Energy Armor and the Hydras. You simply don't make it through Act 2 without those 2 unless masochism is your thing. Even with this setup, it takes a couple of minutes to down a pack of elites.
Plan for 30-50 deaths.
