Okay, here's the thing. I'm playing an Unseen Seer Conjurer (banned Necromancy and Enchantment) in a campaign where we are, essentially, trapped in the Underdark. Currently 11th level, bordering on 12th (casting like a 10th-level Wizard. Stupid GM wouldn't let me dip into Ruathar...). Thing is, while I know plenty of those spells that are just plain awesome, like Evard's Black Tentacles, there's no way in hell I can keep track of all the awesome spells out there. I've picked up Hunter's Eye as my first advanced learning spell, but I didn't decide on the second just yet.
The big problem: the DM blanket-banned the Spell Compendium. Nothing in it is acceptable. (And yes, that means I get to use the more ridiculous versions of several spells. He knows not what he does!)
So, I need a list of the best available spells from anything that's not SpC, environment-based and Races of (which is why he wouldn't let me dip into Ruathar). Yummy divination spells are first on my "to-look" list; good Conjuration spells are second.
I will, obviously, be conducting my own research into this in parallel, but there are just too many books to look into. Thanks for the help.
