At 1st level, a wild stalker's life among the wild has sharpened his senses. He gains low-light vision and a +1 bonus on Perception checks. If he already has low-light vision, he gains a +2 bonus on Perception checks instead. This bonus increases by +1 for every four levels after 1st (to a maximum of +6 at 20th level, or +7 if the character did not gain low-light vision from this ability). This ability replaces the ranger's first favored enemy ability.
