No key chest farming

Hey, I've been trying to use the search tool like a smart forum person, but I can't seem to find builds for a no key required, chest farming. You know, the ones in the Fow, UW, and SF, that you complete the quest and open the chest without a key? Looking for a build for any of the places, I'm not sure if its even possible, but if someone has some suggestion as to what I can do, or any nice builds that can help me do these, I would greatly appreciate it.

necro solo fow, monk + necro duo uw [do ice king & the IW-lvl 15 guys] quests..

win HoH.. =D

These quests cannot be soloed, and even if they could it would not be worth since I've never seen anything gold coming out of a non-key chast...

I have seen a gold items come out of the first fow quest chest but only purple from uw. I only say this from my own personal experience it is probably possible in uw.

You're best luck is to win HoH. I'm assuming you are trying to get the rare crystalline sword.
