Anyspell

This spell allows the caster to read and then later cast any wizard spell of 1st through 5th level. Such a spell is readable via a read magic ability conferred with the casting of anyspell, but only one spell can be read and cast for each casting of anyspell. Merely reading the titles of spells on scrolls or in spellbooks to find a desired spell does not exhaust the magic of the anyspell; an entire spell must be read. Once anyspell is cast and a wizard spell is read, the wizard spell is retained in the priest's mind until the priest casts it. Such wizard spells are cast precisely as if by a wizard of the same level as the casting priest, except that the user of an anyspell needs no material components to work the wizard spell.

While the priest has the wizard spell in mind, she or he cannot pray for a spell to replace the still-pending anyspell. In effect, one 4th-level spell slot is "lost" until the wizard spell is cast, at which point the duration of anyspell comes to an end. Note that in order to make effective use of this spell, the priest must borrow the spellbook of a wizard friend or use a found wizard scroll. (Priests of Mystra are not otherwise able to use wizard scrolls.) Using a scroll in this fashion uses up the spell read from the scroll.
