Human is probably the best race either way. If you have Mask of the Betrayer, you have a decent bundle of Prestige Classes to choose from, Arcane Scholar of Candlekeep and Red Wizard of Thay are both solid. If you know the Tabletop D&D, the same basic build and spell selection works in the OC very well, especially since you'll have Big Stupid Fighters with you pretty much inevitably. You'll want Focus, but keep in mind that later on you probably want access to Isaac's Greater Missile Storm due to game engine limitations so banning Evocation isn't really viable.

No forbidden school conjuration.You can run a fairly solid straight Wizard in the game Scroll access is somewhat limited but meh. I'm fine with a build requiring lawful good, or chaotic evil or anywhere in between but no changing mid stream No LA greater than 0 unless completely unavoidable I'd also like to be able to be the designated item crafter if doing so won't cripple my build too badly since the two NPC casters you grab are built so horribly. I'm playing through Neverwinter Nights 2 Original campaign agian and am wanting to go through as an arcane caster this time instead of my usual druid or rogue.
