Following the tradition of the fixed list casters: The Seer (3.5)

[Frog Dragon]

Seer
The trade of a seer is one specific school of magery. One with a simple main teaching. "Knowledge is power." Therefore, the forte of a seer is knowledge and how to use that knowledge.
Few things stay hidden from a seer and both their mundane and magical knowledge is great. A seer is also well-prepared. Their assortment of arcane abilities functions just as well for shielding oneself and others from harm the seer has likely predicted in advance. Thus, while a seer's offensive power is hardly great, their knowledge and skills as a magical protector are invaluable.

|Advanced Learning, Superb Seer|6|6|6|6|6|6|6|6|6|5[/table]

Skill Points: A seer gains 4 skill points per level+intelligence modifier. Quadruple amount at first level
Class Skills: The class skills for a seer are as follows; Appraise (Int), Concentration (Con), Craft (Int), Decipher Script (Int), Gather Information (Cha), Knowledge: All skills, taken separately (Int), Profession (Wis), Sense Motive (Wis), Speak Language, Spellcraft (Int)

Weapon&Armor Proficiencies: A seer is proficient with all simple weapons, no armor, and no shields.

Spellcasting
A Seer has a list of spells she can cast from spontaneously, like a sorcerer. Any spell from the list can be cast, as long as the seer is high enough level to cast the spell. The DC:s for a seer's spells are 10+Spell level+Int Modifier of the seer. A seer gains bonus spells based on intelligence.

Seer's Wisdom
A seer seeks out any knowledge she can in case it might turn useful one day. Treat this ability as the bardic knowledge ability.

Improved Protection
Any time a seer casts a spell that grants a numerical bonus to armor class, the amount indicated on the table is added to the bonus.¨

Improved Divination
Anytime the seer uses a divination spell, the DC is increased by the indicated amount.

Extended Protection
All abjuration spells cast by the seer have their duration doubled.

Spellsight (Spell Like Ability)
The seer may cast detect magic at will as a spell-like ability.
Spellsight II
The seer may cast arcane sight at will as a spell-like ability.
Spellsight III
The seer may cast greater arcane sight at will as a spell-like ability.

Advanced Learning
The seer may add any abjuration or divination spell to his spell list, assuming he is high level enough to cast it. The spell must be found on the sorcerer/wizard spell list.

Superb Seer
Any divination spell that has a chance of returning false or no information, has this chance halved. Any spell or power of a level lower than 7 that would obstruct the seer's divinations, is ineffective.

* From the Spell Compendium

This has a few rough spots, such as a pretty much total lack of offense. I don't know how to really fix that while keeping the theme so ideas are welcome. There are also dead levels. Again, ideas welcome.
Anyway, PEACH

[jiriku]

Reciprocal gyre (SC) is a decent abjuration spell that deals damage. It's not the greatest, but it's something. If you feel like expanding the focus slightly to divination/abjuration (the "pure" schools of magic, as it were) you might include the various chromatic/prismatic spells. That gets you good defense and offense, although those spells are mostly high-level. Also, have a look at brain spider (SC). It's a cleric spell normally, but might make make sense on this list.

I'd recommend you consider Speak Language as a class skill.

Spellsight III: I think you meant greater arcane sight.

[Frog Dragon]

Yeah, greater arcane sight. Copypasta fails me.
I'll look into spells from other lists. I don't want to take too many spells into the main list from the sor-wiz list, because I don't want to make advanced learning obsolete.
