Improved Combat Throw
Benefit: In melee 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, which the character can make even if he or she is unarmed. Attacking unarmed in this way does not provoke an attack of opportunity.
Special: This feat doesn’t grant the character more attacks of opportunity than he or she is normally allowed in a round.
