Greater Wild Empathy
Your natural empathy stretches across the world of nature.
Prerequisites: Knowledge (nature) 5 ranks, wild empathy class feature.
Benefit: You gain a +2 insight bonus on wild empathy checks, and you may use wild empathy to duplicate an Intimidate check rather than a Diplomacy check. In addition, choose one of the following creature types: elementals, fey, lycanthropes, plants, or vermin. You may influence creatures of that type with wild empathy, if their Intelligence score is 1 or 2. Once you choose the type of creature, it cannot be changed.
Special: You may select this feat more than once. Each time, you may choose an additional creature type to influence.
