wizard spell-learning rest (as opposed to preparation) time

[richard develyn]

You need 8 hours rest before you can prepare your spells, which you take in bits (minimum 1 hour).

If you don't prepare all of your spells, do you need another hour's rest before preparing some more?

No you don't need to rest again to fill up spell slots you deliberately left open.

Quote:

When preparing spells for the day, a wizard can leave some of these spell slots open. Later during that day, he can repeat the preparation process as often as he likes, time and circumstances permitting. During these extra sessions of preparation, the wizard can fill these unused spell slots. He cannot, however, abandon a previously prepared spell to replace it with another one or fill a slot that is empty because he has cast a spell in the meantime. That sort of preparation requires a mind fresh from rest. Like the first session of the day, this preparation takes at least 15 minutes, and it takes longer if the wizard prepares more than one-quarter of his spells.
