I'm playing online Hardcore Classic NL using Blizzard as my main skill, with Firewall for immunes as backup. But frankly, Firewall sucks for anything that moves. I was considering doing a respec into Fireball instead, but does it get enough damage splitting points with blizzard? Which one would be better as the main skill?
I would like to do as much of the game solo as possible, though I know it will be challenging for a sorc. I read the classic guides for sorcs, however those are all single element builds meant for rushing. Fire/Cold is the best hybrid right? I can deal with having to save and exit to respawn super uniques with favorable immunities.
My items are all rares or magic at this point. I haven't found any of the uniques useful for casters yet. Where are good areas to farm at this stage? I've done Hell Andy a few times, but I'm getting too close to death for comfort too often. My fire and lightning resistance are about 60 in hell, I haven't found any diamonds yet to put in a shield.
