No flaws makes it a LOT tougher. I doubt you can do it before 3rd... maybe not even then. I do think the quickest trick will be Divine Metamagic applied to Heighten Spell, though. This gives you the technical ability to cast 9th level spells (since Heighten changes the actual level). Then you'll need some feat or class to give you actual knowledge of 9th level spells.
So maybe Human Dread Necro with Southern Magician, Heighten, and DMM: Heighten. Does that work? Throw on Arcane Disciple to get Wish, but that'll bump it up even higher.
As I read that, you could Heighten the spells that you can cast to level 9, but you couldn't cast an actual level 9 spell. Even if you took A.D. (Envy), you still wouldn't have the actual ability to cast Wish, even though you could cast Touch of Idiocy, DMM: Heightened to 9.
I hope I'm missing something, because that would be great.
How much TO allowed? Pun-Pun or a hivemind could do it around level 1 or so.
Pun-pun assumes Sarruk, which can't be assumed in every campaign world.
Hivemind doesn't F***ing work, it relies on combining 3.0 rules with the 3.5 rules that over-write them, as well as variant rules that are left up to the DM.
I'd rather stay away from obscene TO, but I can't really quantify what that means very well.
Though TO that works would be better than the above two
Arias doesn't like the hive
That's like saying SorO doesn't like "Spellcasting is (Ex)".
The Rules as Written don't like certain things, it is just that I'm the one who brought up the point about the Hive. 3 times, not counting this thread (because I don't want to spell it out again).
(not exactly what you want)
Cleric with the DMM heighten stuff can take the Customize Domain feat Magic domain gets any arcane 8 other domains can get a specific 9. http://brilliantgameologists.com/boards/index.php?topic=2777.msg181830#msg181830
All of the spells that are relevant are already on the Cleric list too, except for a few that are already on domain lists.
... neat though, TY.
I figure a Fester and a Target both (!) with a Magic Mantle dip 1 can go Psychic Chiurgery with a psi 9. (also not exactly what you want)
I don't understand. What are "a Fester and a Target both (!)"?
Well, there's always Mystic Ranger/Arcane Theurge/Sublime Chord shenanigans.
Sublime Chord gets level 9 spells at its 9th class level. With its prerequisites having two skills at 13, the earliest you could enter it would be level 7 if your DM lets you have all of your bloodline levels early, or level 8 if you can only have 2/3.
