The best place to mf at is baal. Solely for the fact that he can drop any item in the game. But your better off hitting pindle because although he drops less items, hes easier to get to and kill.
if you only have a little bit of time on your hands (and no maphack), go for baal runs with a good teler. if you do have maphack and only a little bit of time, i'd go for pindle, eldritch, shenk. If you have maphack and a lot of time, go for meph...drops a lot of little goddies.
ya and u got the old never fails in andy and meph, but voll gave a good tip. mfin at mausoleum or however u spell it. it has been working out quite well for me
supa WTF....if u have MH do PINDLE HUH!!!!!!!!!! DO FUCKING pindle and shenk and w/e w/o maphack PINDLE right there and SHENK and w/e the fucker other name is is RIGHT BY FRIGID WP
