I was doing fine until I made a really terrible multi-classing decision a few years ago. I had about 6 levels of Politician (I can tell because my hit points, Fortitude and Will saves did keep going up every few years, not to mention my Bluff and Diplomacy) and had just taken one in the Sell-Out PR Flak PrC and then, for some stupid reason, I decided to start taking levels in Scholar. Except for a couple of Charisma-based skills, these classes don't stack together at all well; furthermore nobody told me Scholar has no good saves.
I'm also suspecting I'm not human because I seem to be taking some kind of experience point penalty and this hideous negative modifier (-20) whenever I try to use my Charisma-based skills on human females.
Now, what's this nonsense about having trouble leveling? I'm pretty sure everybody here can remember leveling at one point or another. You're just complaining because your classes have D2 hit dice and no BAB progression (like the 3.0 Halfling Outrider).
