OK, first... slowthehelldown!

You gave us 70 minutes to help you. Considering none of this is live chat, you gotta give it a while before someone responds.

If you want to do Hell Baal runs, I'd recommend a Blizzard sorceress as most things there are Fire Immune.

Things to max: Blizzard/Glacial Spike/Ice Blast/Ice Bolt/Cold Mastery(Maybe).

Aside from that, just get your other useful skills like static and teleport, and you should be straight.
