I've always liked good ol plain sorcs for mfing.
Good for any mf boss if you can make em right. Cows/Pindleskin (Nova), Meph (Frozen Orb), etc.
You should use Tals armor + Tals Ammy + 15% Tals Belt, Oculus, 2 30% Nagel Rings (Or Occy rings if you arent legit), Chance Gaurds (Around 40% would do the trick), Shako, 40+% War Travs and a shield depending on what boss you're gonna be mfing on:
Mosers Circle (2x Umed / P.Diamond) for Meph/Diablo/Baal, Rhyme for Cows / Pindle (or Mosers for Pindle if hes light enchanted)
You'll also want 900+ life. I would recomend over 1k for Diablo / Baal.
Or 700+ for cows.
Max Warmth for nova if you're gonna use it for pindle / cows / diablo cause it eats up a lot of mana.
If you need any more help feel free to contact me if this helps.

Maybe tonight we'll fly so far away... We'll be lost before the dawn...
