A rock gnome can create a clockwork device with 1hp. The ability states that it takes 1 hour to build or repair the device.
However, there is no clear rule as to what happens when the device is “killed,” i. e.: it gets caught in a fireball spell.
I assume the device would turn back into shrapnel that they need to rebuilt over an hour, but I believe I can use the mending cantrip to repair it in one minute.
Would this work RAW, and could I take it a step further and use mending to recreate the “repair” mechanic to keep it functioning for another 24 hours?
