Order
True, but that would mean my personally having to tailor the wards to each specific individual which would take an inordinate amount of time. And if I were unable to perform the wards - for instance if I had laryngitis, the wards would be..useless.
Ideally, if a 'blanket' ward could be created, someone else could be taught to use it and it could be used in emergencies or where time is of the essence.
