1: Start with AT LEAST 14 con.
Yup.
2: Don't use those superior effiency clickies, try to find a potency item. (Same effect in a non-clickie version)
You mean efficacy, not effiency. And actually, what you really want are several of the +75% 3 minute clickies, or their equivalent potions. Potency is nice, but not required if you can keep the clickies up.
3: Take Haste and Wall of Fire ASAP
Entirely Optional. Update 9 was actually pretty awesome for Sorcs, so you might want to check it out. Wall of Fire=no longer required.
4: There is no really good multiclass for the Sorcerer class, tho I've seen a few with 2 levels of rogue for evasion/UMD
Meh.
5: You will want either a spell penetration item or the feat/enhancements from level 12 or so since alot foes have SR in mid-high level content
Web. Or even better, Web + Solid Fog. I have never needed more than this.
6: Get an heavy-fort item (Minos legens is an awesome one)
Yup.
7: Fearsome robes can save your life more than once

, tho some melees can be annoyed by the ennemies running away from them
Fearsome is a bad idea. Learn how to avoid aggro or jump/circle strafe instead.
8: Stoneskin is costly, yes, but worth the plat
Wands/clickies if you can. Saves a spell slot.
9: Max your UMD as Sorcerers can reach in the low 40s with a good charisma, which is just enough for Heal scrolls
For fleshies. Optional for WF
10: The best races for a Sorcerer are IMO, WF Human Drow, in this order
Warforged indeed. For the rest, If you want More CC and Instakills via necro, go PM instead. PM is far better at it, has more feat slots for spell pen + necro/enchant focus, and has better survivability than a fleshie sorc. Sorc is all about the DPS now.
Will add more soon
P.S: This is an awesome guide for anyone new to this class
