Dell's Quick Mending

Dell the practical engineer that he is, always wondered why the spell mending took so long to do, so he decided to try and empower it. So he tried to overclock the spell to make it faster.

This spell repairs a single break or tear in an object you touch, such as a broken chain link, two halves of a broken key, a torn cloak, 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. But after each casting of the spell you must roll a d20 if you roll a 1 you can't use this spell again until you finish a long rest

This spell can physically repair a magic item or construct, but the spell can't restore magic to such an object.
