You can read the entrails of a freshly killed animal or humanoid to gain an insight bonus equal to your Charisma modifier on one saving throw. Alternatively, by observing and interpreting the flights of birds, you may apply a +10 competence bonus on any one skill check. Finally, by charting marks in dirt or stone, or observing the behavior of sand when thrown into the wind, you gain a +4 insight bonus on one initiative check. These bonuses must be used during the next 24 hours and you must declare you are using the bonus before the check or save is made. Making a natural divination takes 10 minutes. You may use natural divination (in any combination) once per day plus one additional time per day for every four oracle levels you have attained.
