Mending

(two lodestones)
This spell repairs a single break or tear in an
object you touch, such as broken chain link,
two halves of a broken key, a torn cloack, or
a leaking wineskin. As long as the break or
tear is no larger than 1 foot in any dimension,
you mend it, leaving no trace of the former
damage. This spell can physically repair a
magic item or construct, but the spell can't
restore magic to such an object.
