Cool. Started on the character. As Vertexx points out, as a sorcerer I don't have 3rd level spells. That's a drag, but for a PbP I really don't want to deal with the headaches of determining the spellbook, and how much it costs, etc. Besides, I think I smell a lot of encounters coming. Many slots good.
Lingering Summons looks good, but I want to consult my Complete Arcane and Complete Mage for summoning goodness. So far for feats I've got Spell Focus, Greater Spell Focus, Augment Summoning and Improved Initiative (to go with Rapid Summoning for getting my conjurations to act before the bad guys and in flanking position before my allies) That leaves me with two feats yet to pick.
