Pathfinder, Do Spells Vanish While You Sleep?

In this text, the author discusses the importance of sleep for a wizard’s daily spell preparation and recovery. The author explains that a wizard must first sleep for 8 hours to prepare their spells, refraining from activities such as movement, combat, spellcasting, skill use, or conversation. When the sleep spell duration wears off, the target goes from a magical slumber to a natural one, but not automatically wake up.

The author also discusses the concept of sleep spells, which cause magical slumbers to come upon 4 HD of creatures, with creatures with the fewest HD affected first. Sleeping characters are considered willing to receive spells, and those willingly forgo their saving throw. A sleep spell causes a magical slumber to come upon 4 HD of creatures, with creatures closest to the spell’s point of origin affected first.

The author notes that preparing spells is not necessary for sleep reduction, as it can provide additional benefits in the same day. A full night’s rest (8 hours of sleep or more) can recover 1 hit point per character level. Any significant interruption during rest can be considered an interruption.

The author also mentions that Recuperation gives a full night’s rest in 1 hour, including refreshing daily abilities like spells. A derpy spell called “divine zap” does 1 point of damage at range and can be used to wake sleepers or increase ally damage. Sleep is a great spell for the first two levels, but its usefulness decreases after that.

A slumber spell causes a magical slumber to come upon a single creature, and slapping or wounding awakens an affected creature, but normal noise remains. Overall, the text emphasizes the importance of sleep for a wizard’s daily spell preparation and recovery.
