Salve all,
Magi being who they are, some are trying to learn more from a source than what they can naturally give.
Have you found ways to increase experience sources with magic?
What I have so far, within the rules...
CrMe ritual to permanently increase a teacher's Com
Teaching within a lab with a Teaching specialty (not itself magical, but a magi's solution)
Increase a book's refinement (not a spell, and can be applied to Arts, but it's a way)
Providing a teacher with an excellent piece of teaching equipment (blackboard? a stick?)
That's it
Now, with some extrapolation
InMe to learn directly from a teacher's mind, not being limited by how they communicate
MuMe to increase temporarily the teacher's ability to teach
Finding a magical creature that can provide Affinity with (ability) / book learner / Apt student / etc
From what I understand, experience is itself distinct from Me Art, so one cannot cast a spell on experience itself, but one could improve learning conditions.
It's not hermetic, but a number of hedge traditions have a form of grant virtue. If you use one to grant an appropriate learning virtue such as the appropriate affinity, secondary insight, or book learner that could work. Or the teacher the good teacher virtue.
Step 1: Use Vulgar Alchemy to establish a big Shape bonus for Teaching for some object, such as an academic gown.
Step 2: Get a Verditius to make an Item of Quality that increases the Teaching ability by the Shape bonus.
Step 3: Profit!
I don't have my books to hand, so there may well be a reason this doesn't work (maybe Items of Quality only modify dice rolls?). I rather hope there is.
