ayex, please reply to my PM.
Take a quick search for the Blova sorc guide. It is the blizzard/nova build you are looking for will answer all your questions about the build and it makes a great Baal runner too. I'm not sure if it is posted in here or in the SPF. I don't have it bookmarked or I would link it for you. Good Luck and remember you can cube up those middle runes too. I have cubed up a zod to make a BoTD in SP. I ran cows on players /5 with almost 0% MF and got tons of low and middle runes and cubed like mad whenever the inventory got full. This was b4 LK became "the" place to farm HR's. It can be a change of pace after several mind numbing hours of MF or LK runs. The sheer number of cows with NO MF makes for lots of rune and white/grey item drops.
First round is on me!
Just made a FO/CB sorc and thats enough for me to run Chaos sanct at Players 1 or 3. She already has HOTO and CTA from rune hunting Countess and CS. On top of that CS is fun and you find nice uniques, sets etc.
for me tele to superchests is just too damn boring. But each to his own. Good luck hunting!
