Fell Energy Spell [Metamagic]. Increases the bonuses a spell grants by +2, for undead affected by the spell. Note that it's easy to count as undead. Just use
shroud of undeath.
Also from the A Surge of Theurgy article (as Alternative Source Spell is):
Aligned Theurgy and
Theurgic Specialist (useful to increase CL a lot, for a theurgic necromancer)
Theurgic Bond,
Theurgic Mount and
Holy MountEnspell Familiar You're always considered to be in contact with your familiar. So, for example, you can share buffs with it while it's sneaking into a castle. Or have it deliver touch spells while you're at a distance.
Extra Familiar 1 extra familiar per feat used. You could simulate an entire party pretty easily this way. (Not that wizard's can't
already do so.)
From that one Environmental Racial Variants article (Dragon 280):
Magic-blooded template (also called Spark): +2 Cha, -2 wis, and some other minor bonuses, for +0 LA.
Troll-Blooded It's a regional feat that grants regeneration 1 and makes you fatigued in sunlight. I'll type that again.
It's a feat that grants regeneration 1.
Dragon 310:
Martial Monk: choose your monk bonus feats from the fighter bonus feat list. Monk bonus feats don't need to meet prerequisites. Grab Weapon Supremacy and Shock Trooper in 2 levels of monk.
Dragon 323:
Hummingbird familiar: You're a wizard. You're probably playing rocket tag. Increased init means you shoot your rocket first.
Dragon Compendium:
Death Master class: Not because it's a great class, but because its spell list means that Artificers can make scrolls of Animate Dead at level 1.
Dragon 313:
Half-Minotaur template: Apply to a small race for strength++. Though I may be thinking of half-ogre
Dragon 327:
Diaboli race: Another LA +0 outsider race, in case your DM is sick of Neraphs and Otherworldly elves. Weapon familiarity may qualify them for certain PrCs, I'm not really sure. Also, they're good at intimidation but bad at talking to people (who cares?
)
Dragon 343:
Tome dragons: I've never actually made a build with one, but they were mentioned in the "dragon pc races" thread.
That's all that comes to immediately to mind.
