Through training or an innate quasi-magical connection, you have learned to know when dragons are near.
Benefit: Whenever you pass within one mile of a dragon, you may make a Perception check (DC 10 + the dragon‘s CR) which, if successful, makes you aware of the presence of the dragon. When you are no longer within a one-mile-radius of the dragon, you become aware of the absence of the dragon‘s presence. While this ability allows you to determine the presence or absence of a dragon within a one-mile-radius, it does not allow you to determine the distance or direction of the creature, or if there is more than one dragon.
