Based upon the early reviews/previews of Breath of the Wild, it seems pretty clear that at least when starting out, all of your weapons break with repeated use.
However I'm wondering if this also holds true in the mid- to late-game?
For instance, I'd assume based on some of the promos I've seen that the Master Sword exists in the game, and that as a unique and magical weapon that's significant to the plot it's not possible to just break it fighting some orcs (or bokoblins, or whatever). Would that be correct? And are there any other similarly unique, magical, and non-breakable weapons that can be obtained?
If there are non-breakable weapons available in the game, how early is it possible to obtain one of them (I absolutely hate games that foist you with equipment that wears out and breaks, and will happily go well out of my way to avoid having to deal with this mechanic if possible)?
