Prerequisite: Str 29, Power Attack, Improved Bull Rush, size Huge or larger.

Benefit: Once per round when the monster strikes a foe at least one size category smaller than itself, it may make a CMB check as a free action.

On a successful check, the foe is sent 5 feet, +1 foot for every point by which the CMB check exceeded the target’s CMD. The target lands prone unless it makes an Acrobatics check (as an immediate action) with a DC equal to the total of the CMB check.
