Listen

As you delve deeper into the POIs, it is safer to act cautiously before you venture forward further into the darkness. A good method for raising one's awareness is to stop, keep quiet and listen for any type of sound or voice from the other side of a door. There's a one in six chance that you'll actually identify what's at the other side of a door by listening attentively.

Roll a d6, and if you roll a 1, it means the character identified the sounds corectly. A character cannot attempt to listen through a door again, if he has already failed a check.
