Preparing Spells From Memory

Sometimes a Magic-User will want to prepare spells, but their spellbook may be unavailable; this includes when the book has been destroyed or stolen as well as times when the Magic-User has been captured or trapped. A Magic-User can always prepare read magic from memory. Other spells require an Intelligence ability roll, as described above, with the spell level as a penalty on the die roll. Failure exhausts the spell slot being prepared, just as if it had been successfully prepared and then cast; so if a 5th level Magic-User attempts to prepare fireball from memory, and fails, they will have no 3rd level spells for the day.
