Agile Riposte

You have learned to strike when your opponent is most vulnerable: at the same instant your opponent strikes at you.

Prerequisite:  Dexterity 13, Dodge

Benefit:  Once per round, if the opponent you have designated as your Dodge target (see the Dodge feat) makes a melee attack or melee touch attack against you and misses, you may take an attack of opportunity against that opponent. Resolve and apply the effects of both attacks simultaneously.

Even a character with the Combat Reflexes feat can’t use the Agile Riposte feat more than once per round. This feat does not grant more attacks of opportunity than you are normally allowed in a round.
