At a critical moment, David awakens the [Benevolence System], and his charm can be increased as long as he does good deeds. By offering the head of a sinner to the system, you can gain power and change your physique. "Is this a serious system? Are you sure it wasn't created by a partnership between Tzeentch and Khorne?"
