Replacing the work based activities of servants and grogs with magic is interesting. It can be argued that it helps keep covenant costs or staff numbers down, but also that the vis spent is really wasted as it could be used for so much more (spend silver instead of vis). Simple work replacement devices can turn menial life of the Middle Ages into something akin to our lives in modern times.
These are work replacement spell effects, and some parts are based upon the enchanted devices such as the Abluere Magica (presented in Covenants sourcebook p 52), with parameters changed to affect larger volumes, add extra materials, or to provide more efficiency.
The spells also demonstrate changing the normal spell Target from Individual to Circle or Room.
Work of the Wooden Tub
Rego Herbam / Animal Terram 5, R: Touch, D: Momentary, T: Circle
Clothes and equipment within the circle are cleaned and laundered, as if cleaned by a skilled servant. A very simple Finesse check is required to ensure success (3+), otherwise damage maybe done, items missed, or remain soiled.
(Base 4, +1 Touch, +0 Circle)
Tidy Room of the Pedantic Servant
Rego Herbam / Animal Terram 20, R: Touch, D: Momentary, T: Room
The room and all its contents are ordered, squared away, and stacked neatly, as if performed by a skilled servant. A basic Finesse check is required to ensure success (3+ to 6+), otherwise damage maybe done, items missed, or remain unordered.
(Base 4, +1 Touch, +2 Room, +1 complex materials)
