Just in case summertime in the Galar region was feeling too bright, Pokémon Sword and Pokémon Shield’s Pokémon Dens are about to get a whole lot grimmer. Until August 21, 2022, at 4:59 p.m. PDT, Grimmsnarl will appear more often in Max Raid Battles—lucky Trainers might even encounter a Shiny one!
For an opportunity to encounter this 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. This event does not affect the Pokémon encountered within Dynamax Adventures.
Be sure to read our Pokémon Sword and Pokémon Shield Max Raid Battle Tips article for advice on how to topple these opponents. Don’t wait, though—you don’t want to miss out on the chance to face this powerful Pokémon!
