Ear to the Ground

By lying down and placing your ear to the ground you are able to identify the location and distance of creatures in contact with the ground.

Benefit: As a full-round action you may lie down on the ground and by then placing your ear on the ground automatically detect the location of any creature in contact with the ground to a range of 30 ft.

Special: Wearing a helmet or anything that covers your ears automatically negates this ability. You may take this feat multiple times, each time after the first adding 10 ft. to its range to a maximum range of 60 ft.
