At 11th level, a ranger can, as a standard action, denote one target within his line of sight as his quarry. Whenever he is following the tracks of his quarry, a ranger can take 10 on his Survival skill checks while moving at normal speed, without penalty. In addition, he receives a +2 insight bonus on attack rolls made against his quarry, and all critical threats are automatically confirmed. A ranger can have no more than one quarry at a time and the creature's type must correspond to one of his favored enemy types. He can dismiss this effect at any time as a free action, but he cannot select a new quarry for 24 hours. If the ranger sees proof that his quarry is dead, he can select a new quarry after waiting 1 hour.
