This post is for the replacements to stuff like Power Attack and Weapon Focus. Things that aren't locked to any given kind of character, owing to their mechanical usefulness for a significant variety of them.

Spoiler: Weapon Mastery
Show
[Combat]
Prerequisites: BAB +1, proficiency with chosen weapon
Benefit: You get a bonus to attack rolls equal to one-quarter(1/4) your BAB and a bonus to damage rolls equal to one-half(1/2) your BAB with attacks made using a chosen weapon.
Special: This may be chosen by a Fighter as one of their bonus feats. You may select this feat multiple times, choosing a new weapon for it to apply to each time. This feat counts as Weapon Focus for prerequisites. When you have BAB +4 or greater, this feat counts as Weapon Specialization for prerequisites. When you have BAB +8, this feat counts as Greater Weapon Focus for prerequisites. When you have BAB +12 or greater, this feat counts as Greater Weapon Specialization for prerequisites.

The compacting of so many feats into a single one probably messes up something, but this way a Fighter can afford to generalize more and other people can get the benefits of specializing in a weapon.


Spoiler: Grand Blow
Show
[Combat]
Prerequisites: Str 15
Benefit: On your turn, before you make an attack, you may choose to take a penalty on attack roles up to your BAB until the start of your next turn and gain a bonus to your damage rolls equal to the penalty. If an attack this feat has been used on kills, knocks Unconscious, or knocks Prone an enemy, you may make an additional attack against an adjacent enemy in reach. This may reoccur once per three BAB per BAB-derived attack, minimum once.
Special: A fighter may select Grand Blow as one of his fighter bonus feats. This feat counts as Power Attack and Cleave for prerequisites. When you have BAB +4 or greater, this feat counts as Great Cleave for prerequisites.

Previously, this included Improved Sunder (and was per-turn rather than per-iterative for that matter, but this way retains more of the original functionality for vast scale mook clearing, once reach goes up enough), but that makes more sense as a separate set about . The requirement of some Power Attack for the Cleave makes super high bonuses a bit less problematic, as does capping Great Cleave to a BAB amount.
