Hi all,
- Summae and Tractatus:
I'm in a game where the PC's had access to the Autumn library (phwar..). They are quite powerful, and early on have no lack of things. The players chose it as they didn't want to scrabble for books early on in this game. Amusingly, the players are now scrabbling for books.. for their personal libraries.
Making All Books Tractatus: Seems like a good idea, but some books really don't suit Tractatus, such as the Bible, or Aristotle's Metaphysics, or any of those really core books of the period. People really did read and re-read them and gain more out of each reading.
In future I might make Tractatus common and Summae rare, but I wouldn't take out Summae all together.
- Books and Practice
I have no issue with physical skill books. Even hermetic magic would require practice of the new techniques required rather than just reading it. It may be in your lab, but I highly suspect a fair bit of practice would be required with those.
Physical skills: Indicating people can't learn from physical skill books is.. well, wrong. It does require practice of course, and the more people the better. I have dozens of historical manuals from things from swordfighting to tennis. If I couldn't learn swordfighting from manuals then I don't know how I would know swordfighting.. today .
