Right now I'm going for a Divine Oracle/Loremaster thing to make a wizard who'll double as a priest of a God of Knowledge.
Divination ftw. I am gonna be running a Focused Specialist/Red WizardDivination is the single most powerful school in the game, as any DM of mine knows. The ability to unravel the entirety of an opponent's buffs and items with a Stilled/Silenced Analyze Dweomer during precombat dialog is unmatchable (spamming Dispel Magic during combat is also extremely powerful, as magic items have minimum caster levels). Using Scry, Greater Arcane Sight, Permanent Arcane Sight, Contact Other Plane, and Legend Lore give any wizard the only thing he needs to win any battle: forewarning for his spell selection...
Spoken like someone who has never broken games with divinationThey're very fun. They will also make the DM hate you if he does not expect it. I'd suggest going Wizard/Master Specialist/Something more balanced
Incidentally, if you want to play a specialist, Diviner isn't that powerful compared to a Transmuter or Conjurer.
Ban Enchantment as your second school, or Necromancy if you dislike negative energy, although Necromancy is fairly powerful.
Divination is a weak school! It has nothing on the mighty school of thread necromancy!Spoken like someone who has never broken games with divination
