All 3.0 and 3.5 material in all (officially licensed) books and magazines are fair game. My current build:
Race: Changeling
Build: Wizard 5/Mindbender 1/Urban Savant 4/Recaster 2/Hathran 5/XXX 3
Feats: Eathran, Favored (League of Eyes), Leadership, Mindsight
I usually don't build spellcasters, and could use some advice on finishing my build. The basic idea is to learn the enemy's weakness (Urban Savant 4), communicate that weakness to my compatriots (Mindbender 1), and have any and every spell at CL40 to exploit that weakness (Recaster 2 to grab Acorn of Far Travel, Hathran 5 for Rashemi Spirit Magic and Circle Magic).
A few different ways I was considering to finish the build: Incantatrix 3 with extend and persist spell, to be boring and obvious and powerful; Recaster 3 to nab greater arcane fusion, lots of metamagic (twin, repeating, maximize, invisible, etc.), and metanode spell to essentially become a hugely versatile version of the mailman; Urban Savant 3 + Knowledge Devotion to be more of a team player; the dragontouched + snowcasting route to boost save DCs; or, any other three level dip and feat combination you guys think would be better. Though I have been thinking in terms of power, any more thematic suggestions would be awesome.
Also: worth trading scribe scroll + hummingbird familiar (or, +8 to initiative) to become independent of a spellbook and the associated costs (eidetic spellcasting)?
