Ranged Attack of Opportunity (Quality)

When readied in the hand, this thrown or ranged weapon is extremely fast to react. Once per round, any foe who moves with thirty feet of the wielder is subject to an Attack of Opportunity as if the moving creature had just left a threatened square of the wielder. Five foot steps and forced movement do not trigger this ranged attack of opportunity unless other abilities grant that trigger. Note that a weapon with the Ranged Attack of Opportunity quality does not grant flanks or actually threaten any differently than any other weapon, the only benefit is the ability to make an Attack of Opportunity.
