Alignment, Edicts, and Anathema
Remaster replaced alignment with Holy/Unholy sanctification. Edicts define what you should do; Anathema defines violations that can cost divine powers. More flexible than alignment grids.
The PF2e Remaster replaced the traditional alignment system (Lawful/Chaotic, Good/Evil) with a more nuanced sanctification and edicts/anathema framework.
Sanctification (Remaster): Instead of alignment, divine characters choose Holy or Unholy sanctification (or neither). Holy characters deal extra damage to unholy creatures and vice versa. This replaces the complex alignment damage system.
Edicts: Behavioral guidelines your character strives to follow. These come from your deity (if any), your class (Champions and Clerics), and your personal code. Edicts are positive instructions — things you should do.
Anathema: Actions that violate your code. Performing an anathema act may cause you to lose divine powers until you atone. Champions and Clerics have strict class-specific anathema. Example: a Champion of a healing deity might have "allow suffering when you could prevent it" as anathema.
Deity Edicts and Anathema: Each deity lists specific edicts and anathema. These define the deity's portfolio and expectations of their followers. You don't need to be a divine class to worship a deity, but divine classes must follow their deity's code.
Atonement: If you violate your anathema, you may lose class features (especially Champions and Clerics). The Atone ritual or significant in-character effort can restore your standing.
Practical Impact: This system is more flexible than rigid alignment. A character can have complex motivations and still follow a clear behavioral code. The GM and player work together to define what constitutes a violation.
