Parry And Riposte Feat 18
Source Pathfinder Advanced Player's Guide
Prerequisites Opportune Riposte
Your parries and finishers allow you to riposte with the slightest provocation.
You can use Opportune Riposte against an enemy who fails at a Strike against you (not just critically fails), provided you have both damaged that creature with a finisher on your last turn and currently have a circumstance bonus to AC from the parry weapon trait, Dueling Parry, or Twin Parry.
