Wednesday Boy said:Combat Brute (CWar) gives a few options: for each 5 feet you successfully Bull Rush an opponent, you get +1 attack and damage on them in the next round and if you successfully Charge an opponent, and then on the following round use Power Attack with at least a –5 penalty, the bonus damage for the power attack is x1½ for a One-Handed weapon or x3 for a Two-Handed weapon. But that has the prerequisites of BAB+6, Improved Sunder and Power Attack.
Combine this with a two-handed weapon, Shock Trooper and Knockback for the following madness:
Round 1, charge your opponent with full PA (if you Leap Attack, even better, it makes the free Bull Rush even more powerful). You get a free Bull Rush attempt from Knockback that's likely to succeed.
Round 2, you bull rushed your opponent and even charged him, meaning you get +X to hit and damage as well as x3 damage if you use PA with -5, which you're gonna do... If you need to charge your opponent for this second attack, you can do this tactic over and over again.
