Anathema (EFA - A)

You permanently break the divine link between your deity and a lower-level cleric, druid, ranger or paladin who worships your deity, no matter where they are, even if they're on a different plane of existence.

A creature under an anathema can no longer cast divine spells or channel divinity, heal, harm, smite, change shape, or use any other power associated with their divine class. The effect is permanent until you lift it, or it is lifted by a higher-level cleric or druid of your faith who casts atonement (see below) on the target.

As part of casting the spell, you must write the target's true name in a book or scroll specially prepared for this purpose, alongside a list of their crimes.
