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.
