Lennon is pretty much correct. [img]smile.gif[/img]
Ascension makes the final battle a lot better but doesn't actually do much else in ToB. Older versions came packaged with 'Improved' versions of some of the ToB bosses and a little bonus for Sarevok and his old sword, and I think a tweak to restore Bhaalpowers in ToB. I think these are separate somewhere in the current version though.
But yeh, as far as ToB specific mods outside the final battle I think Dorotea's Redemption and The Longer Road are pretty much it - check the forum at
