Fighter Feat Scaling

These sample feats are part of an experiment to help improve the fighter class, in addition to giving the class a bonus feat at every level and a d12 Hit Dice. At this time however, I don't see every feat from the list of fighter bonus feats, being given a scaling effect. So far, figuring the rate of how each feat might scale, is guesstimated depending on how often the feat will likely come into play, as well as the value and potency of its initial benefits.

Combat Reflexes [Combat]
Benefit: You may make a number of additional attacks of opportunity in a given round, equal to your Dexterity bonus (if any). With this feat, you may also make attacks of opportunity while flat-footed. You may also make 1 additional attack of opportunity each round for every five feats you possess from the list of fighter bonus feats (rounded down), including this one.
Special: A fighter may select Combat Reflexes as one of his fighter bonus feats. A monk may select Combat Reflexes as a bonus feat at 2nd level. The Combat Reflexes feat does not allow a rogue to user her opportunist ability more than once per round.

Deft Opportunist [Combat]

Heavy Armor Optimization [Combat]
You have trained extensively with heavy armor, and can better use the protection it offers.
Prerequisites: Base Attack Bonus +4, Proficiency with heavy armor.
Benefit: When you wear heavy armor, you may lessen its armor check penalty by 1 and increase its armor bonus to AC by 1. For every seven feats you possess from the list of fighter bonus feats (rounded down), including this one, you may increase its armor bonus to AC by 1. The bonus to AC this feat provides, is lost whenever you are denied your Dexterity bonus to AC (if any).

Improved Disarm [Combat]
Prerequisites: Int 13, Combat Expertise.

Special: A fighter may select Improved Disarm as one of his fighter bonus feats. A monk may select Improved Disarm as a bonus feat at 6th level, even if she does not meet the prerequisites.

Improved Toughness [Combat]
A creature with this feat is significantly tougher than normal.
Prerequisite: Base Fortitude Save +2.
Benefit: Your maximum hit point total increases by an amount equal to your Hit Dice plus half the number of feats you possess from the list of fighter bonus feats (rounded down), including this one. If and when this total changes, the hit points you gain from this feat change accordingly.
Special: A fighter can select Improved Toughness as one of his fighter bonus feats.

Improved Trip [Combat]
Prerequisites: Int 13, Combat Expertise.
Benefit: You do not provoke an attack of opportunity when you attempt to trip an opponent while you are unarmed. You also gain a +4 bonus on your Strength check to trip your opponent. This bonus increases by 1 for every seven feats you posses from the list of fighter bonus feats (rounded down), including this one. If you trip an opponent in melee combat, you immediately get a melee attack against that opponent as if you hadn’t used your attack for the trip attempt.
Special: At 6th level, a monk may select Improved Trip as a bonus feat, even if she does not have the prerequisites. A fighter may select Improved Trip as one of his fighter bonus feats.

Mobility [Combat]
Prerequisites: Dex 13, Dodge
Benefit: You get a +4 dodge bonus to Armor Class against attacks of opportunity caused when you move out of or within a threatened area. This bonus increases by 1 for every five feats you possess from the list of fighter bonus feats (rounded down), including this one. A condition that makes you lose your Dexterity bonus to Armor Class (if any) also makes you lose dodge bonuses.
Special: A fighter may select Mobility as one of his fighter bonus feats.

Point Blank Shot [Combat]
Benefit: You gain a +1 bonus on attack and damage rolls with any ranged weapon you use against a target that lies within that weapon's first range increment.

This dodge bonus to AC increases by 1 for every five feats you possess from the list of fighter bonus feats (rounded down), including this one.
Special: A fighter may select Point Blank Shot as one of his fighter bonus feats.

Power Critical [Combat]
You are adept in delivering critical strikes using weapons upon which you have focused.
Prerequisites: Base Attack Bonus +4, Weapon Focus (any)
Benefit: You gain a +4 bonus on rolls to confirm critical threats using weapons for which you have taken the Weapon Focus feat. This bonus increases by 1 for every seven feats you possess from the list of fighter bonus feats (rounded down), including this one.
Special: A fighter may select Power Critical as one of his fighter bonus feats.

Note Many feats that previously applied their benefits to a chosen kind of weapon would be changed to affect all the weapons for which one has taken the Weapon Focus feat.

Shield Optimization [Combat]
You've grown adept at bringing your shield to bear, where it is most needed.
Prerequisites: Proficiency with shields.
Benefit: When personally wielding any shield other than a tower shield or buckler, you may increase its shield bonus to AC by 1. For every seven feats you possess from the list of fighter bonus feats (rounded down), including this one, you may increase its shield bonus to AC by 1. The bonus to AC this feat provides, is lost whenever you are denied your Dexterity bonus to AC (if any).
Special: A fighter may select Shield Optimization as one of his fighter bonus feats.

Stunning Fist [Combat]
Prerequisite: Improved Unarmed Strike, base attack bonus +4.
Benefit: You must declare that you are using this feat before you make your attack roll (thus, a failed attack roll ruins the attempt). Stunning Fist forces a foe damaged by your unarmed attack to make a Fortitude saving throw (DC 10 + half your character level + your Wis modifier), in addition to dealing damage normally. A defender who fails this saving throw is stunned for 1 round (until just before your next action). A stunned creature drops everything held, can’t take actions, takes a -2 penalty to AC, and loses his Dexterity bonus to AC. You may attempt a stunning attack once each day for every four levels you have attained (but see Special) and once for every four feats you possess from the list of bonus fighter feats (rounded down), including this one. You may not attempt more than one stunning attack each round. Constructs, oozes, plants, undead, incorporeal creatures, and creatures immune to critical hits cannot be stunned.
Special: A monk may select Stunning Fist as a bonus feat at 1st level, even if she does not meet the prerequisites. A monk who selects this feat may attempt a stunning attack a number of times per day equal to her class level, plus one more time per day for every four levels she has in classes other than monk. A fighter may select Stunning Fist as one of his fighter bonus feats.

Weapon Focus [Combat]
You have developed your techniques for using a select variety of weapons.
Prerequisites: Base Attack Bonus +1
Benefit: Choose one group of weapons with which you are proficient. You gain a +1 bonus on all attack rolls you make using weapons from the selected group. This bonus increases by 1 for every eight feats you possess from the list of fighter bonus feats (rounded down), including this one.
Special: You can gain this feat multiple times. Its effects do not stack. Each time you take the feat, it applies to a new group of weapons. You may instead choose unarmed strike or grapple (or ray or missile, if you are a spellcaster) as your weapon for purposes of this feat.

Weapon Specialization [Combat]
You deal extra damage using weapons upon which you have focused.
Prerequisites: Base Attack Bonus +4, Weapon Focus (any)
Benefit: You gain a +2 bonus on damage rolls using weapons for which you have taken the Weapon Focus feat. This bonus increases by 1 for every six feats you possess from the list of fighter bonus feats (rounded down), including this one.
Special: A fighter may select Weapon Specialization as one of his fighter bonus feats.

Other recently drafted feats:

Tower Shield Optimization [Combat]
You have trained extensively with tower shields, and can better handle them in battle.
Prerequisites: Base Attack Bonus +4, Proficiency with tower shields
Benefit: When personally wielding a tower shield, you may lessen its check penalty by 3, lessen its attack roll penalty by 1, increase its maximum Dexterity bonus to AC by 1, and increase its shield bonus to AC by 2. For every six feats you possess from the list of fighter bonus feats (rounded down), including this one, you may increase its shield bonus to AC by 1. The bonus to AC this feat provides, is lost whenever you are denied your Dexterity bonus to AC (if any).
Special: A fighter may select Tower Shield Optimization as one of his fighter bonus feats.

Note I always felt the penalties for using a tower shield were a little too burdensome, and instead of revising the shield itself, I decided offering a feat like this would prove a better remedy.
