Pokémon Trainers will soon be able to access the “Enigma Stone”- a mysterious in-game item that will allow players to encounter and catch the elusive legendaries Latios and Latias.

The stone can be received via a Wi-Fi connection from Saturday, July 31, through Friday, August 27.

The stone means that players will also get the “Soul Dew”, an item that increases the Special Attack and Special Defense of Latios and Latias. “Only Pokémon players who have beaten the Elite Four, claimed the National Pokédex, and have two or fewer Wonder Cards can solve the riddle of the Enigma Stone to capture Latios for Pokémon HeartGold Version or Latias for Pokémon SoulSilver Version,” say Nintendo. The Pokémon will both be at level 40.

All lovely, and it’s great to see more Wi-Fi events. However, these aren’t the rarest of legendaries, as you can get them with a run through of Pokémon Emerald and a trip to the Pal Park. Check out Serebii.net, the best Pokémon site there is, for more details. Careful you don’t get cuaght up in EV and IV training like I did last time I visited that site.
