Potion of Distant Audience

This ghostly white liquid allows the imbiber to hear as if he were within a distant area. The area to be listened to must be declared upon drinking the potion. If the area is not known to the imbiber (i.e. he has never been there before), he must pass a normal saving throw, or nothing is heard. Adventurers particularly like these potions to listen behind doors for monsters awaiting them, or to eavesdrop on the plans of villains.
