Dear Moon Studious, love your game even if at first I found it hard.
My suggestion is one related simple itemization. I find it strange that the repair item used for urgent gear fixes outside of town is in the form our a power, could we not instead have a small parts repair kit depicting a small hammer, needle and thread and a few fits of metal and leather. That would be for more believable then powdering your sword/gambeson with some dust and have it magically repair itself. Let the player feel like he/she fixed their own gear in a pinch. Your model team could make a new model for the repair item in a very short amount of time and many others games used this idea in the past. Besides this is what Medieval reenactors use too.
Best wishes, Marius
