Far from it, in fact, as many Mega Stones are available in-game once the main story is completed, whilst the remainder are avaialble via download code now that the distributions have all begun. Here, we’ve put together a table showing you how and where to find Mega Stones, which Pokémon can Mega Evolve in Sun and Moon without transferring them from Pokémon Bank, and where you can find the Key Stone to make it all possible, too. Now though, the distributions have finally opened up for every Mega Stone that wasn’t already obtainable in the base game, so below we’ve compiled one unified list for all Mega Stones and how to get them in Pokémon Sun and Moon. List of Sun and Moon Mega Stone Locations As you can see from the table, the Mega Stones are split between those available in-game, and those available via download code. Interestingly, the distribution ends on October 31st 2017, not long before Ultra Sun and Ultra Moon are released, and it’s unclear if and how these Mega Stones could be transferred to those games, or if they’ll be available in them from the off, instead. As for how the stones were first distributed, those not available in-game were given to participants of online tournamints a month after it took place, and than become available to non-participants a month after that via download code. Unforuntately however, after the above codes expire, there’s no other way to get them, as they won’t transfer from X and Y or Omega Ruby and Alpha Sapphire to Sun and Moon. That means we’ll need to grab them while we can before the distribution ends! Need more tips?

Key Stone - for defeating Dexio on Ancient Poni Path, after defeating the Elite Four.
Once the Elite Four’s been taken down, head back over to Ancient Poni Path, where you’ll be stopped out of the blue by Dexio. He battles you on the spot, with a fairly strong Psychic-based team, before awarding you both the Key Stone and Alakazite for your victory. From then on, if you have the relevant Mega Stone, you can finally Mega Evolve your Pokémon in battle. We’ll update this page as the Mega Stones become more available, but for now we recommend making sure you’ve acquired every Z Crystal too, and get started on grinding those Battle Royals and Battle Tree for Battle Points!
