1st: this is the wrong place to post this
but ok, I wanna help you, people find nice rare items at bosses in hell most of the time, also andariel, diablo, baal, mephisto are the nice drops, also in the chaos sanctuary (diablo) there are minibosses by activating those seals, they also might drop well, but ofcourse people get really nice items by stacking a lot of magic find %. I hope this helped you so far
pm me if you need more info
