If your dex bonus to AC is denied, does this affect your CMD?

In the combat section we learn that CMD uses the following formula:

Quote:

CMD = 10 + Base attack bonus + Strength modifier + Dexterity modifier + special size modifier + miscellaneous modifiers

[...] Any penalties to a creature's AC also apply to its CMD. A flat-footed creature does not add its Dexterity bonus to its CMD.

Lets say a swashbuckler is dueling with a fighter. He uses his bluff skill to feint the fighter and attempts the disarm maneuver on his next attack. Is the fighters CMD affected in any way by the feint?

While the fighter is denied his dexterity bonus to AC, he is not flat-footed. The CMD calculation factors in the regular dexterity modifier as opposed to the dexterity modifier to AC, so it wouldn't change at all. I'm not sure that not being able to apply a bonus would be called a penality either, as penalities usually describe a flat decrease to something.

So while I feel the CMD should be affected by the feint, I'm not sure it is. Maybe penality is meant to be a broader term here, not only describing flat decreases, but other stuff that affects your AC as well?
The most elegant solution would probably be to use the dexterity modifier to AC for the calculation in the first place but that doesn't seem to be the case as written. Anything I missed?


I don't think it specifically says so anywhere but...

So I'd say it does.

While maybe not absolutely RAW, I would have a hard time swallowing that someone denied their dex bonus to AC wouldn't also have their dex bonus denied to CMD, since CMD effectively replace AC to determine if a combat maneuver is successful. Especially with that first sentence.

Yes.
