One of my players is a bard. He cast a Charisma buff on himself and declared that he could now cast more spells because he gets more bonus spell slots for his new, temporary higher charisma. Now the Sorcerer in the party wants to take a Charisma buff to keep giving himself and the bard additional bonus spells all day long.
I can't find anything in RAW that addresses this situation directly. A wizard or cleric would have to prepare a spell in the new slot so that is less useful, but a spontaneous spellcaster could get an unlimited number of spells per day as long as the charisma buffs hold out because they gain a slot, and don't have to prepare a spell to use it.
So my questions are these:
1. Does a temporary buff give a spontaneous caster more bonus spells they can cast?
2. Can they use it to re-use those slots over and over?
