Vesper Primer+Constant Effects+No Trace

No Trace (Ex)

At 3rd level, a ninja learns to cover her tracks, remain hidden, and conceal her presence. The DC to track a ninja using the Survival skill increases by +1. In addition, her training gives her a +1 insight bonus on Disguise skill checks and on opposed Stealth checks whenever she is stationary and does not take any action for at least 1 round. Every three levels thereafter, the increase to Survival DCs and the bonuses on Disguise and opposed Stealth checks increase by 1.
