Valefort did not mention that the Frost Mage on his build is actually Archmage for Spell Power I and II. Eldritch Knight is a 9/10 spell casting progression class, Dragon Slayer is currently a 6/10 spell casting progression class. (Dragon Slayer used to be a 5/10 spell casting progression class.) And thus, today, the build would reach caster level of 31. It requires that +3 charisma item to cast ninth level spells, but as a Sorcerer you can just focus on picking up buffy-gish spells and cast them as stilled as you go.
As for your build, when you turn your Blood Component on, your build should be able to reach caster level of 30, which grants that Greater Dispel Immunity on this server. Thus over all, your build should be able to do fine enough, and get along with the Wizard-Supremacist drow city of Sshamath.
However, there are few points of contention I would like to point out.
1) Your character will not have spontaneous spell casting, so you will need to pick and choose which spells and which slots to Still and which to not. If you get dispelled, and you need spell X to survive, you might be on a short trip to Fugue. While it is not a game breaking handicap - it is still something of a handicap - until you have the areas figured out.
2) You have no reason to pick Spell Focus (Enchantment) and (Abjuration), in Valefort's build those were required to qualify for Archmage. Additionally, a year ago we did not have the server's custom
Polymorphing. Therefore, I believe you would be better off by switch those two feats for Spell Focus (Transmutation) and Augment Form. Thus, when you use spells such as Polymorph Self, or Shapechange, you can actually have the BAB of 27 while in the shifted form.
