Could you provide a citation for that ruling, please, rift wolf?

A 362

CMB and CMD are Pathfinder's answer to simplifying special attacks -- called combat maneuvers in Pathfinder -- such as trip, disarm, and grapple.

CMB is the number you use whenever you're initiating one of those special attacks. You roll a d20 and add your CMB; if you meet or exceed the target's CMD, your maneuver is successful.

CMD is your defense - sort of like armor class - against combat maneuvers initiated by others. If, for example, the dragon wishes to grapple you, it must roll a CMB check, and its total must meet or exceed your CMD.
