Ghost Steps

 
Prerequisite(s): Dex 13+, Move Silently 10+ ranks, Tiger Treads on Eggshells
 
Benefit: Thanks to the knowledge of acoustics you can, should you choose, cause the sound of your footsteps (as well as your breathing and the rustle of gear) to issue forth from any direction and location within a 30 ft. radius. With a successful Move Silently check, enemies are not aware of your real location and hear your ghost steps for what they are, echoes. Ghost Steps does not work in areas affected by Silence effects or when underwater.
