Cleric: Deity

As a cleric, you are a mortal servitor of a deity you revere above all others. The most common deities in Pathfinder have edicts, areas of concern, and the benefits you get for being a cleric of that deity.

Casting spells with the unholy trait is almost always anathema to deities who don't allow unholy sanctification, and casting holy spells is likewise anathema to those who don't allow holy sanctification. Similarly, casting spells that are anathema to the tenets or goals of your faith could interfere with your connection to your deity. For example, casting a spell to create undead would be anathema to Pharasma, the goddess of death. Many actions that are anathema don't appear in any deity's formal list. For borderline cases, you and your GM determine which acts are anathema.

If you perform enough acts that are anathema to your deity, you lose the magical abilities that come from your connection to your deity. The class features that you lose are determined by the GM, but they likely include your divine font and all cleric spellcasting. These abilities can be regained only if you repent by conducting an atone ritual.
