Keep it Down - SU

You know how to twist the passage of sound and light to conceal even the most violent of combats. You can spend 10 minutes with a weapon to muffle its sound and light; it loses the bright property, if it had it, and no longer makes noise or bright lights related to its function; such weapons reduce the penalty to Stealth checks made to snipe by 5, and increase the DC to perceive combats they are involved in by 10.

In addition, you can expend your psionic focus at the beginning of combat to project an aura as a spread centered on you, with a radius anywhere from 10 feet to medium range (your choice; once you set the size of this spread, it remains that size for the duration of the combat). Sounds and bright lights twist in this aura, preventing them from escaping as they should; creatures outside of it must succeed at a Perception check with a DC equal to 10 + 1-1/2 your specialist level + your key ability score modifier to realize that combat is going on in that area. Those that fail are under the audible, visual, and olfactory impression that all is as it should be, though if they enter the aura they can perceive the battle as usual.
