How high can you go before getting +1 BAB?

[Ysgarran]

Then again, I don't have all of the splatbooks so many of the above classes are PrC that I've never heard of.

I don't have everything in front of me at the moment but I used all of the spatbooks by WotC (Defenders of the Faith, Masters of the Wild, Sond and Silence, Tome and Blood and Sword and Fist) and the FR campaign books.

When I have everything in front of me tomorrow I'll break down where the extra spell-caster levels come from. The main one that I'm not 100% sure about is the Virtuoso. I used the extra spell-caster level from that Prestige class to increase the wizard level.

I treated it like a puzzle to solve. Of course, using an early version of PCGen did help immensely...

later,
Ysgarran.

Too much time on my hands...I almost got to Level 20 with a +0 Bab but I messed up at the final level and added a second level of "Master of Shrouds". Incredible will save though...

You could add Alienist, prereqs Knowledge Arcana + Planes at 8 ranks and the alertness feat. That's one more level. And maybe Eldritch Master to finish? Prereqs Knowledge Arcana at 8 ranks, Spellcraft at 6 ranks, and Diplomacy and Intimidate at 2 ranks each. That should get you to 20.
