And then there was one. One! Just one Sage left!
And not only that, but I’ve upgraded my sword using a couple of Master Ores, and I managed to find the Blue Mail (which was in the Swamp Palace, even though some people on MiiVerse told me it was in the Ice Ruins – pfff, idiots).
On top of that I’m also most of the way through the final remaining dungeon (bar, I presume, Lorule Castle), which happens to be the Dark Palace. It’s a bit confusing, and very dark, but the enemies are a complete walkover. It would seem that despite the name and perceived level of evilness the dark suggests, this is intended to be a dungeon done much earlier in the game. Not that it matters!
