CMB Question

[Kalyth]

in the rules for using CMB it says

"make an attack roll adding your CMB in place of your normal att bonus."

Does this mean you add your full CMB even if you are using one of your intertive attacks to perform say a trip?

Logic would seem to me to have you adjust your CMB to the BAB that was left for that attack.

Example: +10/+5. Use +10 attack to hit with sword then use +5 attack to trip. Would you use your Total CMB or would you recalculate your CMB based on the +5 bonus of that attack?

The main eyebrow raiser for me is that it uses the words "normal attack bonus" rather than normal BAB (Base Attack Bonus)

you use the same bab for the cmb that the attack would have

so if your bab is 10/5 and you make an attack then trip the trip uses 5 + all the other numbers, not 10

ok i am pretty sure that i am not wrong on this but if i am im sorry.

the way it works is when adding your cmb you add your base attack bonus to it( str+ Base attack bonus= cmb) so lets say a str mod of 3+10,5 base attack bonus= 13,8 so if you are using your second attack for a cmb then you would roll a d20 and add the +8

To clarify:

The formula for CMB is BAB + STR + Size.

If you are high enough level to have iterative attacks, you have more than one BAB. For example, an 11th level fighter has three different BAB scores: +11, +6, and +1. When he makes his second attack, he uses his second BAB score, regardless of whether that is a melee attack or a combat maneuver.

Later it says: "Combat maneuvers are attack rolls, so you must roll for concealment and take any other penalties that would normally apply to an attack roll."

I believe that's supposed to imply that the -5/-10/-15 penalty for iterative attacks would still apply.
