Vesper Primer+Attacks of Opportunity+Deed: Opportune Parry and Riposte (Ex)

At 1st level, when an opponent makes a melee attack against the swashbuckler, she can spend 1 panache point and expend a use of an attack of opportunity to attempt to parry that attack. The swashbuckler makes an attack roll as if she were making an attack of opportunity; for each size category the attacking creature is larger than the swashbuckler, the swashbuckler takes a –2 penalty on this roll. If her result is greater than the attacking creature’s result, the creature’s attack automatically misses. The swashbuckler must declare the use of this ability after the creature’s attack is announced, but before its attack roll is made. Upon performing a successful parry and if she has at least 1 panache point, the swashbuckler can as an immediate action make an attack against the creature whose attack she parried, provided that creature is within her reach. This deed's cost cannot be reduced by any ability or effect that reduces the number of panache points a deed costs.
