And here is my questions:

1) Where should I go next? Vaults became incresingly hard for me with stone giants, ettins and yaktaur parties at every step. I don't think I can take on Vault:8 right now Did Vaults got a boost in recent trunk? I don't remember upper levels being this hard.

2) Which spells should I learn and which ones should I forget? I'm still looking for Alistair's Intoxication and Borgnjor's Revivification, but no luck so far. I've found a Book of the Dragon in a shop. Would Dragon Form worth for it?

3) Should I branch into Summoning? With which spells?

Any other critique and comment is welcome.

Lee's Rapid Deconstruction isn't exactly a great spell, but you can destroy stone and metal walls with it, which is occasionally useful.

LRD also is amazingly effective against bony monsters like skeletal warriors and skeletal dragons. You've cleared Crypt, so you know how packs of the former can get.

[tormodpwns]

If you're willing to invest a bit more in Summoning, maybe 5 levels or so, you should be able to cast Shadow Creatures reliably (with your great Int and spellcasting skill). Shadow Creatures is awesome ecause it doesn't need loads of spell power and is extremely powerful in Zot.
