1: Start with AT LEAST 14 con.
2: Don't use those superior effiency clickies, try to find a potency item. (Same effect in a non-clickie version)
absolutly wrong, you suould stock up on the clickies. They give 75% to spells, while potency gives 50% the ingame description is wrong
3: Take Haste and Wall of Fire ASAP
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
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
6: Get an heavy-fort item (Minos legens is an awesome one)
7: Fearsome robes can save your life more than once

, tho some melees can be annoyed by the ennemies running away from them
8: Stoneskin is costly, yes, but worth the plat
9: Max your UMD as Sorcerers can reach in the low 40s with a good charisma, which is just enough for Heal scrolls
10: The best races for a Sorcerer are IMO, WF Human Drow, in this order
Not really, the -2 DC warforged gets is not worth the self healing at all. Drow and human can self heal via heal scrolls, while getting more benefits. Personally, i wouldn't make a WF sorc. People say the self healing is great. Well, heal scrolls work just fine. The spells from WF are for those who don't know how to avoid damage, and need an easy button to heal. If you know what you're doing, heal scrolls are plenty. The -2 DC is more than you think, and is more than just 10%
Will add more soon
P.S: This is an awesome guide for anyone new to this class
