Player's Handbook[]
Characters with religion proficiency know the common beliefs and cults of their homeland and the major faiths of neighboring regions. Ordinary information (type of religious symbol used, basic attitude of the faith, etc.) of any religion is automatically known by the character. Special information, such as how the clergy is organized or the significance of particular holy days, requires a proficiency check.
Additional proficiencies spent on religion enable the character either to expand his general knowledge into more distant regions (using the guidelines above) or to gain precise information about a single faith. If the latter is chosen, the character is no longer required to make a proficiency check when answering questions about that religion. Such expert knowledge is highly useful to priest characters when dealing with their own and rival faiths.
Player's Option: Skills & Powers[]
Religion: A character with this proficiency is familiar with the basic tenets of the major and minor faiths practiced in the campaign world. Observing an act of religious significance—a blessing of warriors before battle, for example—means the character understands the importance of the ritual without a proficiency check. Checks are required to understand the activities of unique or foreign religions. Additional character points spent on this proficiency can expand a character's knowledge to include other religions, or can increase the level of detailed knowledge about the faiths already studied.
Campaign Option: Council of Wyrms Setting[]
This proficiency is described in the Player's Handbook. This is assumed to be one of the following: general knowledge of the prevailing religion among the local vassals, general knowledge of the Custodians of Concordance, general knowledge of a religion of a local monster group, or general knowledge of a personal patron. Specific knowledge requires a proficiency check. Adding a second proficiency in the same religion gives specific knowledge (such as its organization, rites, holy days, etc.). Dragon religion is detailed in Section II.
