Advice on sorc

Either Orb or blizzard. If I go orb though, I can go tstorm as well, as I'll only have to max frost bolt, orb, and cold mastery. I can still to tstorm and lit mastery. If I go bliz, however, I'll have to max 5 cold skills (bliz, mastery, and 3 synergies).

What i would do, max blizz and synergies, put one or more after u max everything out into orb, w/ all ur +skills it will do decent dmg but when u have a big boss like baal or meph, blizz kills in no time.

Blizzard is the way to go.

My ladder sorc tears thru anything that is not cold immune.

Use the combo of Blizzard/Ice Blast. Just Blast things that dodge Blizzard.

I only suggested orb and ts coz i solo 'bymyself' so in hell its hard to kill cold immunes so i go ts. Your soloing with a friend who is an amazon that will do physical dmg and can tank for you somehow. So probably blizzard will do coz it does do more dmg but i dont like the way it works, enemies running out of blizzard. I like hit and run with orb.
