A silly question about (in-game) books...

I can see the use of a Q10 L3 Techniques tome already...
It is a bad book, but instant basics for all your apprentices

(that is when using divide evenly)

Q8 elements

Q6 mind and body

Q6 herbam and animal

Or of course, more colourful books:

Vim and Magic theory

Mentem and Animal

Ignem and mentem (Of anger and passion)

The list goes on, I have quite a few ideas...
