You can only cast this spell if you are an official representative of the church (see anathema) and you cannot use it on a person who holds a higher rank within the church than you do.

Excommunicate has the same effects as ban. However, when you cast it on a member of your faith the effects are far more severe. If the victim is a divine spellcaster, she loses the ability to receive spells or to Turn/Rebuke undead. A paladin also loses the ability to remove disease, detect evil, or Lay on Hands, but keeps her other class abilities. Regardless of her class, the victim cannot benefit from divine spells of her (former) faith – although she can still suffer the effects of hostile magic. If a cleric of her faith attempts to cast a beneficial spell on her, he will sense her status; the spell is lost, but the cleric knows why it failed.

There are no visible signs of excommunication. Under normal circumstances it can only be discovered through the use of detect heretic or by trying to cast a beneficial spell on the target. If the victim is revealed as an excommunicate, the attitudes of any NPCs who share the faith will be reduced by at least one category. In some religions the faithful are not allowed to interact with those who have been excommunicated; if this is the case, the victim will probably be exiled as part of her sentence.

Excommunicate can be removed in the same manner as ban. For this purpose, Atonement and miracle can affect the target. Casting Atonement on behalf of an excommunicate is a serious business that can get the caster herself excommunicated; as a result, the cleric will generally require proof that the victim has repented of her mistakes. Excommunicate is a judicial curse; the saving throw of the spell can be increased through the use of ceremonial force.
