Artificer, Bard, Cleric, Druid, Sorcerer, Wizard - Cantrip Level Spell
Casting Time: 1 Minute
Components: Verbal, Somatic, and Material
Reference: PHB 259
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 o f the former damage.
This spell can physically repair a magic item or construct, but the spell can’t restore magic to such an object.
My Comments: In the past, I’ve had two characters I have played that needed to use mending, each once. One wanted to repair a magic broom that sweeps floors. The magic still worked, but the handle was broken, so he fixed it, because… why not?
Another player got hit by a critical and busted a few links of chainmail. He didn’t have mending and in that case, it would have been really useful. Once.
I can think of other uses, but this isn’t going to be the most used spell in your arsenal. I know, it’s just a cantrip, but it’s a cantrip with a 1 minute casting time, all three components (V,S,M) and that includes using 2 lodestones every time. Are you going to carry around two lodestones? OK, to be honest, a lot of players and DMs ignore material components when it’s slowing things down, but the point is still there.
Here are some uses I can think of; you busted a door handle to get into a room and want to leave without a trace, your arrow was broken when you went to retrieve it, you want to fix that rope bridge you have to cross, you broke the chain of a necklace as you grabbed it off an idol and ran for your life and now you want to fix it… Anything else?
All in all, I would be glad enough to have access to it, but I wouldn’t cry if I didn’t.
