I searched for an existing answer to this and found none, so I figured I'd ask. The correct forum seems inactive for the most part.
I have a Bard 10/Ranger 2/Rogue 2. Upon taking level 14 (a bard level) the level-up dialog box said that his BAB was increased from +9 to +10. I started thinking about this because it didn't seem to mesh with what I thought his BAB should be.
The wiki says that bards and rogues both get 0.75 BAB per level, and rangers get 1.0. Also, the wiki says that the numbers stack for multi-class toons. Based on those values:
BAB = 12 * 0.75 + 2 * 1.0
BAB = 9 + 2
BAB = 11
This is kind of an important stat for the toon, since his number of arrows during manyshot is based on it. Anyone know why poor Sanjurow is getting only +10 BAB at level 14 rather than the expected (by me) +11?
