In the APG, does the listed version of Wild Empathy replace that ability in the Core Rules?
Or does it add to the Core Rules?
Specific example: Lion Shaman- does he only have Wild Empathy with Felines?
Or... does he receive a bonus to using the standard Wild Empathy with felines?
The lion shaman gets a +4 bonus on Wild Empathy checks with felines, and can use Wild Empathy as normal with creatures appropriate to the original ability.
