it's kind of hard to break down exactly what a "stat" is for an item. i've chosen to make it as general as something numerical that helps calculate a game interaction, but even this feels too specific and like it'll need a lot of future work.
besides, what's an item? a weapon, sure. a weapon mod, probably. a consumable potion, yeah, why not. but what about a quest objective? what about a status effect? are they even items?
