It doesn't not have to be bosses as well.

You can join a created game with travincal quest done in act 3, walk to durance level 2 waypoint and make your own game.
Kill mephisto for quest and join a game with travincal already finished, have 0 magic find and kill travincal over and over. Have fun enjoy this supreme mf technique!
