Petrosha87 on YouTube has posted a video of him soloing Diablo on Inferno. One key aspect to his Monk build is that he has gotten his attacks speed up to 3.2 attacks per second. You can also check out full descriptions of his build and gear. The build he uses is not just for bosses either. He claims you can use this build to help kill elite packs as well as farm other bosses for some great gear.
He also posted a few comments to help users trying to follow his build:
The build is great as long as you have the gear to support it. I would suggest staying with Dodge mantra (with armor if you want to be defensive or backlash if you feel you don't need it) until you reach 650+ resist, 4,5k+ armour and 600~ life on hit with 30k+ hp. Thats when things start becoming more bearable for monks
Lindail has also shared numerous areas within Act 1 to help you through your character leveling. Inferno or low level gear grinding is covered in a multitude of areas. You can check out the full list of his videos in his original thread.
This video is a quick spot for people just getting into Inferno. There is a random dungeon that can appear with an elite monster for a nice chance to drop some gear to help you gear up for the rest of the challenges ahead.
While it's really cool that this is possible - I just noticed that every single piece this person has - probably costs up against millions on the auction house. So yeah, i won't be soloing even act III Any time soon - as i do not want to farm millions for this kind of gear.
I hate farming. And i love diablo.
Kind of a conflicting relationship isn't it?
