An ex-paladin is a paladin or paladin warrior who ceases to be good, who willfully commits an evil act, or who grossly violates the paladin code of conduct. A paladin must be of good alignment and loses all light abilities if he ever willingly commits an evil act. He loses all paladin spells and abilities (but not weapon, armor, or shield proficiencies). Even many members of the Argent Dawn are known for having cast off paladin armor to find ways to turn the Holy Light toward destructive uses.
