Momentum Swing: To use this maneuver, you must charge
a foe in the first round, and you must make an attack using
your Power Attack feat in the second round. The penalty you
take on your attack roll must be –5 or worse. Your attacks
during the second round gain a bonus equal to your attack
roll penalty × 1-1/2, or × 3 if you’re using a two-handed
weapon or a one-handed weapon wielded in two hands. For
instance, if you choose to take a –6 penalty on your attack
roll, you can deal an extra 9 points of damage, or an extra 18
points if you’re using a two-handed weapon or a one-handed
weapon wielded in two hands.
虽然没有明说取代原来的猛力伤害,但是应该是替代没错……
