Pokémon Go’s new Shadow Raids will give players a second shot at Shadow Legendaries

A new type of raid is coming to Pokémon Go this month: Shadow Raids. Niantic announced the in-person-only raid type on Thursday, giving players an alternate way to catch Shadow Legendary Pokémon like Mewtwo by battling in gyms. Shadow Raids will also introduce Shiny Shadow Legendary Pokémon to Niantic’s mobile game, and a new mechanic that will see players face tougher, “enraged” Shadow Pokémon.

Shadow Raids will go live in Pokémon Go on May 22, as part of the game’s Rising Shadows event. The debut of Shadow Raids will be a weeklong event, with one-star and three-star raids featuring Shadow Pokémon running Monday through Friday. On Saturday and Sunday, Legendary Shadow Pokémon will appear as Shadow Raid Bosses, starting with Mewtwo.

Three-star and five-star Shadow Raid Bosses will become enraged (and stronger) as players battle them, but Pokémon Go players can use a new item called a Purified Gem to quell that enraged state. Purified Gems can be assembled using Shadow Shards — earned by battling the lower-tier Shadow Pokémon throughout the week — and an item called the Shard Refiner, which players will get from Professor Willow.

Niantic said Pokémon Go’s new Shadow Raids are an opportunity for players to earn Legendary Shadow Pokémon that they weren’t able to get from battles with Team Go Rocket leader Giovanni. Shadow Raids also can’t be accessed using Remote Raid Passes, another attempt by Niantic to get Pokémon Go players out exploring and meeting up in-person.

“The driver there is really to get players focused on getting out there and playing. Whether it’s Monday to Friday, [or] Saturday/Sunday, we really, really want that to be a main facet of the game,” John Funtanilla, Pokémon Go senior producer, told Polygon in
