Notice that Windshriek Boots are only to boost our AoE so they're not necessery, also you will do just fine without +40% inc damage Bane helmet, It's just great damage boost. I can assure you that with 1ex gear and capped resistances you can go yellow maps right after campaign.

I've done with it all conquerors, all shaper guardians, some synthesis bosses, maven invitation with 4 shaper guardians, sirus AL7 (for him I swapped bisco and windshriek for life gear)

I;m doing full detailed guide for this build so if you enjoy gameplay stay tuned!

Here's PoB for people who don't want to watch video(just copied my character, no shaper damage setup):
