Stone Manipulation

[Poryhedron]

As far as I know, it has no effect whatsoever.

Okay, I finally got a Water Stone after being impatient for too long and looking up the Crystal board in GameFAQs for a faster way to help me obtain one. Turns out there's a trick, and I quote, "Go to your mom and change to and from DST a lot of times, you'll get a lot of phone calls. Sure, you get the same crap just as often, but you'll get the stones faster."

It works... but, there's another small catch that I have observed doing this trick: if the trainer you're trying to to get a stone from calls you and asks for a battle, the next couple of calls they'll call you with are pure ramblings of attempted Pokémon catching so it's best to save before you talk to your mom, turn off your game once you get a battle request from the stone holder of choice, and turn back the game on to try again.
