Over on Twitter, the official Pokemon PR account tweeted-out some valuable info tidbits for Pokemon Sword & Shield.

If you’re curious about those red pillars of light appearing in the Wild Area, well for starters, they are called “Pokemon Dens.” These Dens that release red pillars of light indicate that Dynamax Pokemon are hiding within them. Checking out these Dens will trigger the newly introduced Max Raid Battles.

In addition, the ‘Y’ icon resembling a wi-fi you see in the bottom-left corner of the screen is a feature called a “Y-Comm.” This Y-Comm feature will let players trade Pokemon and have Link Battles both online and in person. By checking the stamp on the Y-Comm screen, players may also join in on Max Raid Battles.

Check out the tweets below:

Trainers—we’ve learned that the Wild Area is full of Pokémon Dens.

Pokémon Dens that are releasing red pillars of light mean that Dynamax Pokémon of different species and varying strength are hiding in them. Investigating these can lead to Max Raid Battles.#PokemonSwordShield pic.twitter.com/7tj6c49T6o
