Occultist [Religion]

Requires Rites Feat 

Your knowledge of the goals and behaviors of cults gives you
deeper insight into dealing with them and what they worship.
You can choose to use your bonus to Religion in place of your
bonus to Deception, Investigation, or History for checks you
make with those skills when dealing with fey, fiends, celestials,
aberrations, or their cults.
