Maneuver Offense

Combat Maneuver Bonus

Each character and creature has a Combat Maneuver Bonus (CMB) that represents its skill at performing combat maneuvers. A creature's CMB is determined using the following formula:

Character Level + (STR modifier -or- DEX modifier) + Size modifier

Size Modifier: Fine -4, Diminutive -3, Tiny -2, Small -1, Medium +0, Large +1, Huge +2, Gargantuan +3, Colossal +4, Titanic +5.

Feats: Some feats and abilities grant a bonus to your CMB when performing specific maneuvers.

Penalties: Any penalties to a creature's attack rolls also apply to its CMB. For example, targeting a creature with partial cover inflicts a -4 penalty to both attack rolls and CMB checks on the creature attacking it.
