Edit: this should be called “Minuscule Movable Lab”, clearly I missed the title.
A quick post with an odd purpose – to shrink a room or lab down to a tiny size so it is easier to transport. For this to work the lab or building would need to be constructed specifically as a container, so that once it is very small it can be picked up like a storage box. Another spell then follows to ensure the room’s contents stay intact as it is carried.
What I really love about using a Target of Structure or Room is that the complexity of all the content is in-built in the effect. There is no additional scaling needed to target everything within the room. My reservation is that these spells are very high level, which means only more advanced PCs might be able to have them.
Chamber as Ornament
Muto Terram 40, R: Touch, D: Moon, T: Room
The target room and all its non-living contents is shrunk to a tiny size; a standard room is shrunk to a thumbnail, with the content also reducing proportionally. The caster can opt to affect only the room’s contents. Requisites are required when cast on non-Terram materials.
(Base 4, +1 Touch, +3 Moon, +2 Room, +2 incredibly small)
For the design of Chamber as Ornament picking the base level was normally for a doubling of each dimension, or an increase of mass by eight times. In Ars Magica it is also generally easier to shrink a thing than to enlarge a thing. When reducing a 16x reduction is reasonable at the base, and for a room that turns a chamber into a chest. A further reduction by adding another magnitude makes that chest into a cup, then another for a cup to a thumbnail.
Another design consideration was the Duration of Moon which is how I see the spell being effective, however both these spells are better as enchanted devices which can be turned on and off.
Then to keep the items in place when the room is shrunk this spell is needed. It might also serve to ensure a lab is slightly harder to break into and ransack. The caster must also have a way to remove it if they need to – which is where the power is probably best as a complex enchanted item.
Keep Everything in Place
Rego Terram 40, R: Touch, D: Moon, T: Room
The target room and all its contents is fixed in place so that nothing can move. Objects stay as placed, doors are held, and pots of water will stay full even if disoriented.
This spell does not affect living targets such as trees, animals, or people. Requisites are required when cast on non-Terram materials.
(Base 5, +1 Touch, +3 Moon, +2 Room)
