Ranger’s Focus (Ex)
Replaces: Favored Enemy
At 1st level, once per day, the guide can focus on a single enemy within line of sight as a swift action. That creature remains the ranger’s focus until it is reduced to 0 or fewer hit points or surrenders, or until the ranger designates a new focus, whichever occurs first. The ranger gains a +2 bonus on attack and damage rolls against the target of his focus. At 5th level, and every five levels thereafter, this bonus increases by +2.
At 4th level, and every 3 levels thereafter, the ranger can use this ability one additional time per day. This ability replaces favored enemy.
