I'm currently in a 3.5-turned-Pathfinder game that we've been playing for the last year, and I've been playing the Heroes of Horror class, the Archivist. In an attempt to Pathfinderize the class, I have built a class known as the Prelate. (Feel free to vote on the class and offer suggestions.)
My question is not regarding the Archivist/Prelate so much as if there is room for an arcane equivalent. Something that gains knowledge based abilities at various levels and can cast any arcane spell. I know that the bulk of arcane spells are already available to a generalist wizard, but the vast bulk of the good divine spells are available to the cleric, so that's sort of beside the point.
I haven't really had much of a chance to flesh out the idea beyond this. Initial inklings have me considering replacing the Dark Knowledge/Divine Study abilities of the Archivist/Prelate with some sort of arcane version of Favored Enemy bonuses (based on monster knowledge checks maybe?). I'd also considered making it both INT and WIS based (or maybe INT/CHA to stick with both current arcane casting stats). Likely just a good Will save (unlike the Archivist's good Fort and Will).
So... thoughts? Suggestions?
