So, we're taking Stone Power's concept and massively expanding on it? Hmm, I'm not sure how much I like a by round total. I'd be comfortable with an encounter model, as you create a buffer between yourself and others that you repair between, which makes more sense to me from a verisimilitude perspective, whether that's putting plates back where they're supposed to be, removing arrows, replacing cut straps, etc.

Does this include shields?
