Shadow Infusion, character level 7th.
As a swift action, you can shroud yourself in shadow for 1 round. While shrouded in this fashion, you have concealment, even in areas of normal or bright light, against creatures that have no ability to see or otherwise sense you through darkness. You can use this feat for 1 round per day per character level you have. These rounds need not be consecutive.
