Warg
Level Ability
1 Wild empathy
2 Animal companion
3 Wild sense (sight or scent)
Wild Sense (Ex): Each time the warg gains this ability, he may choose either sight or scent. If he chooses sight, he gains low-light vision. if he already had low-light vision, he can now see three times as far as a human in poor lighting (or four times as far if he chooses it again, or fives times as far, and so on). If he chooses scent, he gains the scent ability. if he already has scent, the range at which he can detect opponents doubles. At 20th level, the warg's senses are so acute that he gains blindsense to a range of 30 ft.
