Priest Character Creation
Some Priestly Virtues & Flaws:
+3: True Faith. You have true faith in a divinity, granting
you the "granted abilities" commonly associated with devout priests of the deity,
and also the ability to call upon the deity for Miracles. You can also use your
Faith to channel other, less pure faith, thus drawing on the combined might of
entire congregations.
+5: Priest. You are a priest of a minor deity. You have all
of the social rights and responsibilities that go with this, and can employ
priestly magic, limited to the Realms that the deity grants.
+7: Priest. You are a priest of a major deity. You have all
of the social rights and responsibilities that go with this, and can employ
priestly magic, limited to the Realms that the deity grants.
