I agree with Jade on this one... Partially. I would have personally gone Human StP Spell Focused Erudite3 / Specialist Wizard1 / Master Specialist1 / Cerebremancer10 / Archmage5
and just take up Practiced Manifester, Spell Mastery and Uncanny Forethought. Boom. I'm now an Arcanist now (See Netheril: Empire of Magic) with access to my entire spell list at all times with access to an adjustable spell list and the ability to spontaneously cast/manifest whatever the hell I, whenever the hell I want
... But that is just me...
