Duelist's Parry (Ex): At 3rd level and higher, whenever she is targeted by a melee or ranged attack the duelist may spend a point of ingenuity as an immediate action to disrupts the opponent who made the triggering attack's line of sight to her, providing total concealment against that attack if it was made with a weapon. The triggering attack in this round suffers a 50% miss chance if it is made, though the opponent can instead could decide to take any other action, including choosing to attack one of the duelist's allies or taking a full attack action that grants additional attacks against her in this round (if her foe is of high enough level to have additional attacks).

At 9th level, this ability improves, and instead, when targeted by a melee, ranged, spell, or psionic attack, the duelist can spend a point of ingenuity as an immediate action. The duelist disrupts the opponent's line of effect to her, providing total cover against a single attack with a weapon, spell, or psionic power. The triggering attack in this round cannot be made, though the opponent could decide to take any other action, including choosing to attack one of her allies instead, or taking a full attack action that grants additional attacks against her in this round (if her foe is of high enough level to have additional attacks). This does not prevent Area of Effect abilities from affecting the duelist or taking effect in general.
