Hurry and get your Diancie while you can, the vent only lasts July 24-27 for America, Australia, and Europe. [quote]The second Downloadable Event in Pokémon Omega Ruby & Alpha Sapphire gives you a Diancie. This Diancie is more battle ready than the ones in 2014 and will give you access to the Diancite Mega Stone if you take it out of a Pokémon Center and haven't already received the stone.[/quote] via www.serebii.net
