Durability changes too harsh

[Barboron]

And come to think of, why the hell do I lose durability anyway when I just heal people, I'm not even being hit, how does my armor need repairing.

It's a fantasy world and the least relating thing to ours you can find is that? Never mind the giant demon with swords slashing the entire party XD
All the same, you are using your gear's "energy" or whatever BS spin you want to put on it.
