[Psitticine]

A Prophet is permanently Blessed, so if his/her/its Pretender has the appropriate magic, the Prophet might gain Wind Shield, Reinvigeration, Regeneration, etc. I'm not sure if that's what is being referred to however, and other then that, I can't think of any spell-casting benefit prophethood would bring, aside from the built-in boost to Holy/Unholy magic.
