The character is cursed.
A curse is any expressed wish that some form of adversity or misfortune will befall or attach to some other entity—one or more persons, a place, or an object. In particular, "curse" may refer to a wish that harm or hurt will be inflicted by any supernatural powers, such as a spell, a prayer, an imprecation, an execration, magic, witchcraft, a god, a natural force, or a spirit. In many belief systems, the curse itself (or accompanying ritual) is considered to have some causative force in the result.
This trait applies only to characters that are actually cursed by supernatural means, not just jokingly cursed by other characters.
