Pokémon Sword and Shield recently saw the game’s second DLC released, and The Crown Tundra has reintroduced many beloved Legendary Pokémon from previous games, including Cosmog (now nicknamed “Fwoofy”) and all of its cohorts.
Much like Pokémon Sun, Moon, Ultra Sun, and Ultra Moon, initially acquiring Cosmog isn’t a difficult process and goes hand in hand with the game’s story. However, before you hope to be entrusted with Fwoofy, you’ll want to finish the core game’s story.
You’ll need to have beaten all eight gyms and finished out the main story in Pokémon Sword and Shield before trying to get Cosmog. You’re unlikely to be ready for Crown Tundra without doing that, just based on the strengths of what you’ll be up against.
The first battle you face in Crown Tundra is against an opponent with Pokémon as strong as Level 70, which should be a key indicator for you in knowing when you’re ready to travel to and take on the new icy expansion.
How do you get Cosmog?
In order to acquire Cosmog, you’ll need to visit one specific house in Freezington. Inside, you’ll find an old woman who is looking after a Cosmog she has nicknamed “Fwoofy.” Rest assured, you’re not forced to keep that name when you get Cosmog.
She states she’s looking for someone worthy, and the way you’ll prove that worth is by continuing the core story in Crown Tundra. As you go through the story with Calyrex and help it regain its trusted steed, either Glastrier or Spectrier, you’ll encounter the one you chose.
In the process of that story, you’ll have to battle the horse you chose to protect Freezington from it. After successfully doing that, go back to the old woman and she’ll choose to gift you Cosmog, or “Fwoofy.”
How do you evolve Cosmog into Lunala or Solgaleo?
Fortunately, the process of evolving Cosmog into either Lunala or Solgaleo is not a difficult one. You just need to level Cosmog up, which can be done through a variety of methods.
You can simply battle with Cosmog or with it in your party, and a particularly effective way of doing this is to run through the Pokémon League again with Cosmog at the back of your party. It’ll get loads of experience this way.
You can also complete Max Raids, which will come with Exp. Candy and Rare Candies, which help quickly level up a Pokémon. Max Lairs work for this too, as the Dynite Ore you acquire can be exchanged for those items.
Whatever method you choose, you’ll first want to get your Cosmog to Level 43. After doing that, it will evolve into Cosmoem. Continue your path, and Cosmoem will be ready to evolve at Level 53.
Now, whether Cosmoem ultimately evolves into Solgaleo or Lunala will depend on which version of the game you have. If you’re playing in Pokémon Sword, it’ll evolve into Solgaleo, and in Pokémon Shield it’ll evolve into Lunala.
How can you catch Lunala, Solgaleo, and Necrozma in Crown Tundra?
On top of being able to evolve Cosmog into Lunala and Solgaleo, both of those Legendary Pokémon from Pokémon Sun, Moon, Ultra Sun, and Ultra Moon can be captured through the new Max Lair adventure in Crown Tundra.
It may take you some time, as there are upwards of 47 different Legendary Pokémon that can be encountered. If you’re patient, and perhaps a bit lucky, you’ll eventually encounter Lunala or Solgaleo.
Technically, Solgaleo is a version-exclusive for Pokémon Sword and Lunala is a version-exclusive for Pokémon Shield, but if you can connect and play with others that won’t be an issue.
If you choose to do a Max Lair with other players online, you can end up in Max Lairs that are hosted by players of the other version and thus end with a Legendary Pokémon that’s not technically available in your version of the game.
Capturing Necrozma will take a bit more work, and can be a bit trickier. You’ll need to have already finished the other Legendary Quests provided by Peony as part of Crown Tundra.
That means you’ll need to have finished and captured the Regis, caught all three of the Legendary Birds, and caught Calyrex. Fortunately, we’ve got some guides linked above in this paragraph that will help with each of those.
Once you’ve done all of that, you’ll get one final clue that Peony will accidentally drop. Head to the Max Lair to speak to him, and this will unlock Necrozma and all of the Ultra Beasts as findable in Max Lairs.
You may have to try several times to find Necrozma, but keep looking. You can also speak to Peony’s daughter in the Max Lair and sometimes she’ll have information on a Pokémon that can be found in a Max Lair, even Necrozma.
Where can you find the N-Lunarizer and N-Solarizer to fuse with Necrozma?
One of the biggest benefits of acquiring Lunala, Solgaleo, and Necrozma is being able to fuse Necrozma with either one of them to form one of the most powerful Pokémon available in Pokémon Sword and Shield.
In order to do this, you’ll need some special items that can’t be acquired until you have the Pokémon that use them. While I’ve seen it noted you need to have Lunala, Solgaleo, and Necrozma in your game, in my experience I’ve had the items become available with just Lunala and Necrozma.
You’ll need to head to Stow-on-Side and talk to the bargain man on the right. Once you have the needed Pokémon in your game, he’ll give you the items you need.
Once you have them, make sure you have Necrozma and whichever Pokémon you want to fuse with (Solgaleo or Lunala) in your party. Use the item, and you’ll be able to combine them right away.
How to use Pokémon HOME and Pokémon Bank to save some time
There is a workaround if you happen to already have any or all of these Pokémon from playing a previous game. If you’ve played Pokémon Sun, Moon, Ultra Sun, or Ultra Moon, you can move the needed Pokémon into your Pokémon Bank.
From there, you’ll need to transfer to Pokémon HOME and finally into Pokémon Sword and Shield. If you need more information on using Pokémon HOME, we have a handy guide that will help with that.
If you acquire these Pokémon through this method, you’ll still be able to visit the bargain guy in Stow-on-Side to get the N-Lunarizer and N-Solarizer and fuse Necrozma with Solgaleo or Lunala.
