Grimoire User (3.5e Feat)
From D&D Wiki
 Grimoire User [General]
As an academic, you are compelled to make use of a gimoire to keep track of your spells instead of depending on pure intuition.
Prerequisite: At least one level in an arcane spell caster class that does not use a grimoire., Academic Mage
Benefit: The character must scribe their spells into their grimoire. This does not change the number of spells that they can cast per day nor the number of spells that they can know and spontaneously cast. It does however allow them to record spells in their grimoire. Then later after getting a good night's sleep and spending 1 hour studying their grimoire they can learn a new spell in place of one they already know. In effect they mentally "lose" the the old spell in exchange for the new one. The new spell's level must be the same as the that of the spell being exchanged. Only one spell can be exchanged per hour of study and the character can only spend their Intelligence Modifier in hours per day following the good night's sleep.
Normal: Take a limited amount of spells at level up.
