"There is nothing left here except the stench of failure. We need to annihilate the body of the creature so that it is not brought back, and then return to the castle to be whatever help we can."

Here is an interesting debate, I used my spells from yesterday, but had resting long enough to prepare new spells, but had not yet done so. So I can prepare spells, and cast a number that I had not yet cast today, correct?
Example, I used 2 8th yesterday, none today. But I have the ability to cast 3 in one day. I can prepare the three 8th level spells for today and then cast, since I have used none so far today.
