Okay, so it's apparently hard to get a hold of a Dusk Stone in X & Y. Seeing as I want to use and Aegislash, I would like one without having to wait until near the end of the game. So if anyone has a spare Dusk Stone in any of the Gen VI games, I would LOVE for you to trade me it I'll give you the Pokémon you used back, if you want it back.
If you really need one you can get iy from super training just fully super train a mom and it will unlock special training levels you can get stones from including dusk stone
