Fast Talk (Sp): Once per combat encounter, you can make a Diplomacy check as an immediate action to prevent an enemy within 10 feet from attacking you. The foe must be attempting an attack against you at the time you use this ability. If your Diplomacy check result exceeds your opponent's Sense Motive check result by at least 1 for every 3 points of base attack bonus the enemy character possesses, he decides not to attack you (or anyone else) this round. In subsequent rounds, he attacks you only if you attack him first or are the only opponent within sight. If your Diplomacy check fails, the opponent attacks normally, and you cannot use this ability again during this combat encounter.
