So, uh, at the end of the last session I played for Pathfinder, my character hit level 6. Being a Fighter and all, this meant that I got a second hit per regular attack and thus a second Base Attack Bonus. Problem is, not sure how to write this on the sheet. For the BAB itself, it was easy enough to just write +6/+1 but I can't find out how to categorise the CMB and CMD. Whether it uses both, only one of them, or something else entirely isn't mentioned anywhere that I can find (and not for a lack of trying either; I find it weird that something so relevant would be a thing you're expected to just nebulously "know" out of the aether so I probably missed it somewhere).
So, uh, for things like that how do you work it out and make note of it?
