Mending

0-level (Cantrip) Transmutation
Casting Time: 1 action
Range: Touch
Duration: Instantaneous
Components: V, S, M (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 clack, 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.
