Elusive target( Complete Warrior, p. 110)
Trying to land a blow against you can be a maddening experience.
The Elusive Target feat enables the use of three tactical maneuvers.
Negate Power Attack: To use this maneuver, you must designate a specific foe to be affected by your Dodge feat. If that foe uses the Power Attack feat against you, the foe gains no bonus on the damage roll but still takes the corresponding penalty on the attack roll.
Diverting Defense: To use this maneuver, you must be flanked and you must designate one of the flanking attackers to be affected by your Dodge feat. The first attack of the round from the designated attacker automatically misses you and may strike the other flanking foe instead; the attacking creature makes an attack roll normally, and its ally is considered flatfooted. If the designated attacker is making a full attack against you, its second and subsequent attacks function normally.
Cause Overreach: To use this maneuver, you must provoke an attack of opportunity from a foe by moving out of a threatened square. If the foe misses you, you can make a free trip attempt against this foe, and the foe does not get a chance to trip you if your attempt fails.
