The Shaman automatically gains the first rank in Call the Pack upon obtaining level 4. When invoked, the feat causes a Giant Wolf to come to the aid of the Shaman. The Wolf is rather weak defensively but has strong attack potential; each additional rank in this feat increases the offensive capacity of the wolf pack. If the wolf should die, it will be replaced with another of its pack. Up to 4 wolves can appear in total, each appearing after its predecessor has died. The duration of the effect is 1 round per skill rank in Nature Affinity. Activating this feat expends 1 use of Divine Nature.
