Not sure if this is a common question, but I'm AFB so here it is. What happens if a caster is (for whatever reason) deprived of their casting stat item?
Say an Int 22 wizard loses their +6 int item, costing them a 7th, 8th and 9th slot. Presumably we roll for which spells are lost? If the item is retreived on the same day, does the wizard regain the prepared spells, the slots as unprepared (and hence must prepare them again), or does it not apply until she rests?
Alternatively if a spontaneous caster (for some reason I have duskblade in mind) loses their stat item and hence loses the related slots, do they regain them if the item is recovered on the same day?
