Guys, I just had a new thought, inspired by Scott DeWar's directing me to threads where the discussion regards spell abilities in Pathfinder. Anyway, here it is:
It will be a new FEAT, available at 5th level and higher. By taking this feat, you become sort of a hybrid Wizard/Sorcerer. You still have a spell book where you can know, keep, and study an inifinite number of spells, but your spells per day just become SLOTS that can be filled spontaneously with any spells that you have PREPARED. You can still prepare the same number of spells as a regular wizard, but this gives you a little more flexibility in using the spells, because you can use that 1st level slot you planned for Comprehend Languages to cast another Magic Missile, if that Orc doesn't cooperate and die quickly enough.
So, instead just spells known and spells prepared, it becomes a Three-Tier System:
SPELLS KNOWN, SPELLS PREPARED, and SPELL SLOTS TO FILL SPONTANEOUSLY.
[credit for inspiring this idea goes to Scott DeWar, for getting me involved in the Pathfinder discussion threads where some ideas were being discussed that got my bain turning in this direction.
