Lets see what I can do here...
I - Parry
Prereqs: BAB +1, Combat Reflexes
When an enemy makes a melee attack against you, you can try to block the attack by making an attack roll with any melee weapon you are holding. If you are using a one handed weapon and a buckler or nothing in the other hand, you gain a +2 bonus on this roll. Use the higher of your AC or your attack roll as your effective AC against the attack. The bonus increases by +1 for every feat that has Parry as a prerequisite. This is considered an attack of opportunity.
II - Swift Counterattack
Prereqs: BAB +4, Parry
Whenever you successfully block an attack using the Parry feat, you may make a single attack with your highest bonus against the opponent who attacked you. This is considered an attack of opportunity.
III - Sliding Counterattack
Prereqs: BAB +8, Dodge, Swift Counterattack
Whenever you successfully block an attack using the Parry feat, you may take a single 5 ft step (this doesn't count as your 5ft of the round) before or after using the Swift Counterattack feat.
IV - Baffling Counterattack
Prereqs: BAB +11, Sliding Counterattack
Whenever you successfully block an attack using the Parry feat, you may choose a target adjacent to the opponent that attacked you to receive that attack as a free action. That target is flat-footed until the end of the next turn. This can be used with the Swift Counterattack and the Sliding Counterattack feat. If you do, and your attack hits, the enemy you hit becomes flat-footed until the end of your next turn.
