Orb firewall is a build typically used to solo hell CS, some people use it for rushing
May want to consider restat, most mf sorc is blizz or orb with max teleport
Andy, meph is standard
Duriel if you got maphack
Can add in fire eye
If you have firewall you can do bone ash,
If you're skilled you can also do storm tree but hes tough with firewall, also the boss in the ruined temple is good
