Blueholme Spell Books and Scrolls: Adapting for Free Casting

Both clerics and magic-users have spell books in Blueholme.   Each caster has 1 separate book per spell level.   They are described as "Far too large, fragile and precious to carry around on adventures." It leaves it up to the DM how the players get the books for each of the levels.


Cleric books contain all the spells per each spell level, but there are only 8 cleric spells per spell level.  


When an m-u reaches a new spell level he goes through the list of spells (20 m-u spells per level) and rolls his chance to know spell for each, until he's gone through the list at least once and met his minimum or reached his maximum.   18 intelligence magic-users are likely to know all but 1-2 of the spells for each level.


Using the memorization system, casters would be running back to their HQ all the time to re-memorize spells.  Unless, that is, they make a scroll.   You can re-memorize a spell from a scroll without discharging the spell.   Magic-users can make a scroll for 100gp per spell level, Clerics for 200gp per spell level.


I think we, as Jason suggested,  use a free casting system with this proviso:  As long as you studied your actual books within 24 hours, you can cast any spell you know.   If not, you can only cast from spells you have on  a scroll you've had with you to study.


DRAFT OF RULES:

 if a caster has studied his books within the last 24 hours or has not cast spells in any intervening day since he studied his books, he can spend his spell slots to cast any spell he knows.  If he has not consulted his books, he can only cast spells he has studied from a scroll he has with him.

            Magic-users begin with a level 1 spell book.  Dues-paying members of magic guilds receive a spell book from the guild when they reach each new spell level.  If they aren’t in a guild, they must create or acquire a new spell book for 750gp time the spell level.  Likewise, if a magic-user loses his spell book he must create or buy a new one for the same price.  If a magic-user captures an enemy spell book, he may use it to study spells he knows, once he has cast Read Magic on that particular spell in the book.

Clerics receive a level 1 spell book from their temple when they reach 2^nd level and each additional time they gain a new spell level.  If a clerical book is lost or destroyed, the cleric is issued a replacement, but is also assigned a penance task for failing his god. Spell books from another religion do clerics no good.

Spell books are large and fragile.   Each volume fills an entire back pack or saddlebag.  A person cannot carry more than 1 volume (without some sort of magical help) in any circumstance.  Each day a spell-book is carried on adventure, roll 2d6, if the total is 12, the volume has been destroyed in some mishap.   If the book is subject to any sort of water, magical or fire attack on an adventure, it is automatically destroyed.  A book can be transported safely if packed securely in a locked chest, lain flat in a sturdy 4-wheeled wagon that travels on a road. If travelling well-packed in a ship, there is a 1 in 20 chance every 3 days that it will be ruined on the trip.
