Chrales, the world’s most reputable Pokemon GO dataminer, has uncovered a new item in the game’s network traffic.

The new item is called Sinnoh Stone which appears to be an all-in-one substitute to make certain Sinnoh region Pokemon evolve. We do not know when the Sinnoh Stone will be released but it should be soon.

Here’s the official description for Sinnoh Stone:

“A special stone originally found in the Sinnoh region that can make certain species of Pokémon evolve. It is very tough and has a beautiful sheen.”
