This power is not traditional invisibility, but you have learned how to trick someone’s mind into believing that you are not there, as long as you do not prove otherwise.   

Cost: One Rouse check

System: Make one Rouse check and expend a standard action to become invisible, taking with you all inanimate items on your person. Unseen Passage cannot be used to make another character invisible, even if the character is unconscious or dead. While under the effects of Unseen Passage, small sounds, fragrances, or other minimal effects of your presence will be ignored by others. If you emit overpowering odors or make noise any louder than a whisper, your Unseen Passage will immediately end.

If another individual is looking at you when you activate Unseen Passage, the observer automatically sees through this use of Obfuscate. You will be invisible to anyone who was not looking at you when you used Unseen Passage, and, if an observer looks away for more than a few seconds (one turn in combat), she will automatically lose track of you. 

Duration: Until detection
