Improved Combat Throw

The character excels at using an opponent’s momentum against him.
Prerequisites: Combat Throw, Defensive Martial Arts, base attack bonus +3.
Benefit: In mêlée combat, if an opponent attacks and misses the character, the character may immediately make a trip attack against the opponent. This counts as an attack of opportunity.
Special: This feat doesn’t grant the character more attacks of opportunity than he is normally allowed in a round.
