=== Spell Books & Copying Arcane Spells ===
Users of arcane magic must carry a spell book with them in order to study from at least once per day in order to cast spells.  If they haven't studied (had access to) a book with a particular spell in it within the last 24 hours, they cannot cast that spell using one of their slots, even if they have cast it in the past.

* '''Travelling Spell Books''' are 3 lb/ up to 50 pages and not cheap (100 gp/page in rules, 0.06 lb/page); 

* '''Standard Spell Books''' are 15 lb/up to 100 pages and considerably cheaper per page (50 gp/page; 0.15 lb/page).  So half the cost of Travelling Spell Book, but about 3X as heavy. 

If you run out of pages on what you have, you'll have to purchase another blank book to record additional spells. A book can have any number of pages up to the maximumbook (e.g., you can buy a book with 10 pages or 20 pages, I'll pro-rate the weight accordingly.

If an arcane magic user encounters a spell book or scroll and wants to learn and/or copy the spell into their own book, they must:

* Cast ''Read Magic'' on the book or scroll, in order to interpret the writing of another magic user
* Check against the % Chance to Learn (based on INT) for each spell they would like to learn/copy; note there are limits on the total number of spells per level a caster can learn, also based on INT.  
** Characters can check to see if they can learn spells that are above the level they can cast in order to copy them, but they cannot actually cast them until they are of that level.
* The caster may copy the spells from the book or scroll into another book.  This can be done 
** with pen and ink, a process which takes a number of hours equal to the spell level; this method only allows copying of spells at levels that the user can actually cast at their current level; or
** through the ''Copy'' spell, which performs the transcription instantly.   Use of ''Copy'' allows the transcription of spells above the level that can actually be cast by the user, so long as the user was successfully able to learn them.
* Regardless of the manner of transcription, ach spell copied will use up a number of pages equal to (spell level -1) + 1d4.
* If transcribing a spell from a scroll, once the spell is successfully transcribed, it disappears from the scroll itself.  
* Trasnscription from spell books does not alter the original book in any way.
