This spell allows its wizard to convert one spell into another of the wizard's choice. As long as the spell conversion is in effect, when another spell is cast, the wizard may choose to cast it normally, or alter it into another spell. The spell to be altered must be of third level or lower, and the spell to be converted to, must be of second level or lower (the additional level of power is expended in the conversion process) and must be a spell the wizard already knows, although it does not have to be currently memorised.
This spell is usually cast at the beginning of a day or before a known encounter, to give the wizard ample time to replace it in his memory with another spell. Only wizard spells may be converted by this spell - priest spells are not affected by it, and only the wizard's own spells are affected. Range, duration, area of effect, and saving throws are as per the spell being converted to; the spell being converted determines the spell components and casting time (however, in order to convert a spell, a few additional incantations are necessary, and the name of the new spell must also be uttered; this effectively increases the casting time of the original spell by one).
As an example of the use of this spell, let us assume Biff the wizard has cast this spell before a large battle; during the fight, Biff finds himself levitated by an enemy wizard and to be dropped from a great height. Unfortunately, Biff has nearly used up his complement of spells in the battle, and has a single fireball left - not much use in this situation. However, since spell conversion is in effect, Biff starts the incantations of the fireball anyway; when he is dropped, Biff casts the fireball but uses spell conversion to convert it to a feather fall, floating softly to the ground unharmed.
The material component for this spell is the pelt of any were-creature; the pelt is consumed with the casting.
