With this spell the priest calls upon their diety to aid them
by creating a weapon of stone for them to use. They must be able to
touch enough rock that will be converted to a weapon, the volumes
must be the same. The weapon will always be the favored weapon of
the diety. It will act exactly like a normal weapon but will not
effected by rust, not magnatism. At the end of the spell
the weapon will crumble to dust.
