I was thinking that maybe it would be better than simply unequiping your weapon and armor when it breaks to have parts of the armor like a shoulder pad or wristband to fall off and be collected after battle to be repaired to the main under armor later. Or maybe when a sword breaks half of the sword falls off, be picked up and can be repaired later but the other half of the sword with the handle can still be used but with very low damage.

I don't like the idea of having to get the part that fell off. I do like the idea that parts will fall off, just repair them and they will reappear.
