I'm designing a campaign in which surface civilization has largely collapsed, and the nature of the collapse will result in the destruction of most written materials (along with a lot of other things).
Because of this, spellcasters who must research spells- Wizards & Wu Jen- will be forced to work from first principles, and design their own spells. I have 2 methods I'm considering (not neccessarily exclusive): spell design from the ground up similar to True Sorcery or working with downscaled Spellseeds, or having PCs do a Spellcraft check vs a DC to learn a spell- reflecting researching through fragments of magical writings to piece together lost spells.
However, spontaneous casters don't research their spells. The absence of most of these tomes and scrolls won't affect them- they just know their spells.
How can I restore the balance and still remain true to the campaign setting?
