You can bend light around yourself and muffle any minor sounds you make, allowing you to nearly vanish when not moving. Even when you move, you appear only as an outline with blurry features. This cloaking field doesn't make you invisible, but it does make it easier to sneak around. Activating the cloaking field is a move action. While the cloaking field is active, you can use Stealth to hide, even while being directly observed and with no place to hide. Attacking doesn't end the cloaking field, but it does end that particular attempt to hide. If you remain perfectly still for at least 1 round, you gain a +10 bonus to Stealth checks (which doesn't stack with invisibility) until you move.
Your cloaking field lasts for up to 10 rounds before it becomes inactive. While inactive, the cloaking field recharges automatically at the rate of 1 round of cloaking per minute.
