Combat Expertise is no longer an actual feat, but rather an ability gained at BAB +1
Power Attack is no longer a feat as well, but rather an ability gained with a STR of +13
Prerequisite: BAB +1, Int +13
Benefit: You do not provoke an attack of opportunity when performing a trip, disarm, dirty trick, feint, reposition, or steal combat maneuver. In addition you gain a +2 to both the CMD and CMB, all of the above maneuvers, but anything that would result in adding CMB to CMD would not cause the +2 to stack. Lastly, you can choose to use your Dexterity bonus in place of your Strength bonus for only the above maneuvers.
Prerequisite: Dex 13
Benefit: You gain a +1 dodge bonus to your AC, in addition you gain an additional +4 against attacks of opportunity caused when you move out of or within a threatened tile. A condition that makes you lose your Dex bonus to AC also makes you lose the benefits of this feat. Lastly the dodge bonus increases by +1 for every 5 Dex points above 13, such that at Dex 18, the bonus is +2; at Dex 23, the bonus is +3, etc. Any abilities or feat that require Dodge or Mobility are fulfilled by Combat Dodger
Improved Weapon Finesse
Prerequisite: Dex 15, weapon finesse
Benefit: You gain the ability to use your dexterity modifier to the weapon you are using for weapon finesse. Any attacks (but not combat maneuver) that require Strength cannot be used synchronously with IWF, i.e. you cannot use Power Attack at the same time using IWF.
Prerequisite: Dex 13, proficieny with a ranged or thrown weapon
Benefit: You gain the feats Point Blank Shot and Percise Shot. In addition, any feats that require Point-Blank-Shot instead require Percision Shooter.
Dual Weapon Fighting
Prerequisite: Dex 15
Benefit: You gain the feats Two Weapon Fighting and Two-Weapon Defense. In addition, any feats that require Two Weapon Fighting instead require Dual Weapon Fighting.
Improved Dual Weapon Fighting
Prerequisite: Dex 17, BAB +6
Benefit: You gain the feats Improved Two Weapon Fighting and Double Slice. In addition, any feats that require Improved Two Weapon Fighting instead require Improved Dual Weapon Fighting.
Prerequisite: STR 13, BAB +1
Benefit: You do not provoke an attack of opportunity when performing a bull rush, drag, overrun, or sunder combat maneuver. In addition, you receive a +2 bonus on checks with these combat maneuvers. Now a prerequisite for the relevant greater combat maneuver feats.
