When a creature becomes visually aware of you (such as by Spot check), you can use this maneuver to force them to make a Will save (DC 11 + your Charisma modifier); on a failed save, they are flatfooted for 1 round, take a -1 penalty to attacks against you for the rest of the encounter, and will not be able to describe you or recognize you in future encounters unless they successfully hit you with an attack. This maneuver is a supernatural ability.
