first things first... you need to realize that if your not godly at all right now, you wont manage to get the best mf set...you have to start low, then work you way up
my main way of doing things is this: when i get banned (like always) and start over, if i cant find any friends (there all banned too) then i go about making a blizzard sorc, if you need directions for that go to the tips and stratagies section, and find a good blizzard sorc build...or use the search button. secondly, while your making her, get a 3 socket crown (or helm of your choosing with diecent def) and socket it with P topaz's, you just got 70 something mf (cant remember exactly, i think 72) next, find some nagels , that will giv eyou anywhere from 25-30 mf depending on ur luck, i never run into anything weaker than a 25 so yeah... then find some rare boots w/ 20+ mf, then a goldwrap. and there, you just got a noob mf setup.
with this gear, do meph runs in hell, youll slowly start to aquire items, trade the ones you dont want for mf gear (if your lookin for mf gear and you find a vampgaze, then find bartucs, try to get a shako and p chancies or something)
make sure you know what the value of stuff is (if all else fails ask these forums)
also: if you cant find the noob gear. do meph runs anyways, mf helps, but you can find stuff off of him without any MF
after getting good items on your sorc, start doin hell pindle (i recommend pindlebot, but some will go against that as it may bann you)
