Skill: Knowledge: Religion
Knowledge: Religion is the result of training and understanding of faith, aspect, and divinity. The secrets of deities, dogmas and otherwise, and the realms of divine creatures both sublime and sinister are open to those with this knowledge, understanding the religious slants of all things mundane, magical, and all between.
Mechanically, Knowledge: Religion is used more often for faith related areas and categories than other skills, including performing various acts and miracles when called for it, or looking past the wool over the eyes of the misled. Talents for Knowledge: Religion further this, giving various ways for others to perform great acts.
