The Nimbleton Hold
(Alteration, Enchantment)

Range:  0
Components:  V, S, M
Duration:  1 day
Casting Time:  1 turn
Area of Effect:  The caster
Saving Throw:  None

By means of this spell, the wizard places a number of spells "on hold" for the next day. The spell is intended for casting at night, before sleep. The held spells are stored in the wizard's memory for the evening undisturbed. If the wizard is awoke, the spells are available to him, and are used up normally when cast. In the morning, the spells are still retained, and will remain with the wizard as though he had spent the time to memorise them that morning.
The wizard may retain a number of spell levels equal to 9 + 2 per wizard level (i.e., a 9th-level wizard may retain 27 spell levels worth of spells). The material component is any form of headpiece (hat, hairnet, comb, skull cap, whatever) and must be specially enchanted by the caster of the spell. The cost to construct this item is 500 gp. The item must be worn both while memorising the spells to be retained, and when the Hold spell is cast, though not while casting the spells.
Note that because a cast spell is lost as per usual, the Nimbleton hold must itself be memorised and cast every day (therefore, a 9th-level wizard saves himself 270 minutes memorisation time in the morning, but at some other time during the day must spend 50 minutes to memorise and cast the hold. Thus, his total savings are 220 minutes, or three hours and forty minutes. In addition, the wizard may defend himself with the held spells during the night or morning before memorising the next day's list).
