Mega Evolution

A mechanic from Generation 6 Pokémon X/Y games, this feature was released on PFQ on November 21st, 2013.
When you have the Mega Ring, you'll also get a random Mega Stone from Prof. Holly and a section at the Merchant's will become available.

How to Mega-Evolve a Pokémon

Visit Doug the Merchant. The last section, Mega Evolution, has a link to said page. Once there, you'll see a list of Pokémon in your Party. If you only have Eggs, it will tell you that there are no Pokémon. Select the Pokémon you wish to Mega-Evolve. A warning shows that the Mega Stone will break in the process. Next, you can choose how long the Mega-Evolution will last.

• 7 days = Credits
• 28 days = GP
• Forever = ZC
