Any character who's unlocked this particular proficiency is able to instinctively notice and recognize signs of a disturbance in the immediate vicinity, thus reducing by 1 in 6 the character's chance of being surprised whenever he or she makes a successful proficiency check. Assuming he or she is able to communicate this information to the others in the party, their chance of being surprised is also reduced by that amount.
