The Halloween spirit is looming large over Pokémon Sword and Pokémon Shield. From Thursday, October 29, 2020, at 5:00 p.m. PDT until Sunday, November 1, 2020, at 3:59 p.m. PST, Ghost-type Pokémon will appear more frequently in Max Raid Battles. During the event period, be on the lookout for spooky Pokémon like Cofagrigus, Trevenant, Gourgeist, Mimikyu, and Polteageist in Pokémon Dens—if you're lucky, you might even encounter a Shiny Gourgeist!
To encounter these Pokémon in a Max Raid Battle, you'll need to connect your Nintendo Switch system to the internet through Y-Comm or by selecting Mystery Gift in the X menu, then selecting Get the Wild Area News. After that, whenever you see a pillar of light shining from a Pokémon Den, you can walk up to the Pokémon Den and interact with it to start a Max Raid Battle with a Dynamax Pokémon.
Be sure to read our Pokémon Sword and Pokémon Shield Max Raid Battle Tips article for advice on how to topple these giant opponents. Don't wait, though—you don't want to miss out on the chance to add these Pokémon to your team!
