Why to max TS? If TS kills the bonus wont be added. A good mf sorc is on my opinion FO/1CM + Nova/LM
Get Max block. No point into energy. ES is crap... it burns your energy. Get Thundergods + maxed res. Meph wont almost do any dmg to you.
Maxing CM is NOT recommended. While maxing FO is ABSOLUTE recommended. The higher CM goes upp in skill , the lower the percent will be. Anyway you get a high lvl CM from your items.
FO on high lvl do very great dmg.
Then rest on the lightning skills. The remaining put it on def skills or some points into CM.
And sorc items is very cheap... generaly the main ppl here who are playing Diablo II is not totaly noobs. And since the last dupewave im sure they can get some free items.
Oh btw how many orbs are meph required from Your char before he dies? Tell me why FO is not on maxing again. Not good dmg?
