I may be missing something here - The rules in covenants for taking over a lab says that you can use a laboratory without having to spend time making it your own if it is designed as a transient lab, and gives the shared labs at Durenmar as an example. Covenants doesn't give any further info I can find about shared labs, in terms of what having a lab be a 'Transient' lab does to the design.
I've checked both the HoH:TL book and the Guardians of the Forest book (being places where lots of Durenmar stuff is explored) and there is nothing there either that I can find - also searched the forum and found very little about this. The lack of questions on the forum makes me thing there are rules about communal labs I am missing - can someone point me to them?
I'd have thought there would be some limits to how developed they might be with features / limits to features etc - but so far as I can tell any lab can be transient with no restrictions on how it can be built up, and so all labs probably should be, to allow apprentices to work in them with the increased bonuses they can give, so you could rent highly specialised labs to people who would otherwise never have access to them, etc? There are cannon reasons not to do this (sanctums etc) but I can also see a market for someone having a really high CrCo lab specialised in LRs they rent out to people.
I feel like I am missing something here - are there rules I have overlooked? If not do people have any house rules for this?
