Mega Stones can be used to mega evolve Pokemon.
How to find them
There are currently three ways to obtain a Mega Stone:
- You can get one from the Gem Cauldron by boiling 5 Gems of each type within the given time limit. You will have to wait 2 days till the boiling is done.
- You can rarely find one when playing the Treasure Hunt game in the Game Center.
- You can get one by exchanging some Fish Pokemon & Big Pearls with Leah the Mermaid at the Emera Beach.
- Some Mega Stones can also be obtained through special events.
How to use it
You can Mega Evolve a Pokemon only if it has a Mega Bubble on its summary page. You can mega evolve it by giving it the Mega Stone to hold, and letting it reach Level 50.
- Mega Stones are tradeable.
- Mega Evolution is not reversible.
