This is the deal. One at a time, we each get to spend a season in Sigmundo's Library. You can spend that time Studying or Copying. He will provide the facilities and materials needed for either.
Also, each of us as we visit shall bring one book from our current library, and he shall send us each home with a better copy of that book.
At first I planned to give you each a tricky decision: should you copy or should you study? But you would figure it out in the first few visits anyway. So instead I decided to make it so either way has advantages & disadvantages.
The best thing to do is copy, which Sigmundo is strongly trying to influence you guys to get in the habit of doing (writing in general really). Now, if you notice on the wiki of the Library, I dropped the Well Bound/Scribed/Illustrated optional rules from Covenants, but kept the others. I didn't want to futz with it all, and wanted people just to be able to write books just like they do in the core rules. Actually, that is half true. I do have another version of the library that includes those options and two-dozens more that my mad genius forced me to invent. I decided to cut them all and simplify
No matter what your Scribe score, you may copy the contents of one entire Summa no matter how large. You may also copy a number of Tractati equal to your Scribe score. Available topics include the Hermetic Arts, or any Ability from the core rulebook. You may choose to copy Spell Lab Texts, calculated at the normal rate but with a special choice of spells.
The book you copy will have the following scores...
For a Summa on Arts, the maximum level is 15 and the maximum Quality is (25 - Level).
For a Summa on Abilities, the maximum level is 8 and the maximum Quality is 14 + (3 x (8 - level).
You may copy a number of Tractati equal to your Scribe score, but the sum total Quality scores of them all may not exceed 32, and the maximum Quality score of any one of them may not exceed 14
For Spell Lab Texts, you may only choose from old spells. Spells printed in the cannon of earlier editions. Examples include the Wizard's Grimoire or the WGRE. The mechanics of the spell will have to be revised as well as possible for ArM5, but this spell will result in the same Level, Arts, and the same general effect (or maybe the exact same effect). Some of these spells were a little loopy in their own editions, let alone probably bending the current rules somewhat as well. Go for it. These will be unique rare gems in your collection. Carmen is choosing CrAu35 Fulgurous Orb for example
But if you want to study something he won't let you copy...
The Arts don't get much better, but he has texts on almost any topic imaginable (abilities outside the core rules, such as mystery lore or some strange ancient magic). He also has academic texts that he won't let you physically touch. Just view it through the glass using the magical flameless lamp, tap the glass to turn the page.
If you want to be greedy and study just for yourself, Sigmundo will laugh at you for wasting your time and tell you to choose from the same stock you could copy from.
But if you agree to write a book, promise and swear to do so within seven years, he will let you into his secret collection for study. Antonio did this, it is in his journals (which is how we know it now), and you may notice he has some pretty meh books in our library collection.
Level is irrelevant (you get to study once, and you find something in range). The maximum Quality is 20 for Academic or General Abilities, 10 for occult abilities (mysteries, ancient magic, etc), and 15 for other Abilities.
Then there is the book you bring in. Whatever it is, somehow it will be improved. But it has to be one of our existing books that survived the fire, not anything obtained afterward.
so, I got to wordy again, didn't I?
