Pokémon Scarlet and Pokémon Violet are now available for Nintendo Switch. Read on below to learn more about a new in-game event:
Catch Lots of Clefairy in a Mass Outbreak Event
Paldea is getting a rare visitation from Clefairy, some of which may have the Upbeat Mark.
The full moon is calling in the first Pokémon Scarlet and Pokémon Violet mass outbreak event. Until October 1, 2023, at 4:59 p.m. PDT, mass outbreaks of Clefairy will be appearing not only in Kitakami but also the Paldea region, where Clefairy can’t normally be encountered. Lucky Trainers are in for an additional treat: Clefairy encountered in these special mass outbreaks are more likely to have the Upbeat Mark!
Mass outbreaks are a phenomenon in which many of the same species of Pokémon appear in one location, and when you catch a Pokémon with a mark—such as Clefairy with the Upbeat Mark—you can choose to have a title associated with that mark displayed when you send your Pokémon into battle.
To participate in mass outbreak events, you will need to download the latest Poké Portal News and install the latest update data for your game. While purchasing The Hidden Treasure of Area Zero is not required to participate in this mass outbreak event, there may be future mass outbreak events that occur in locations that cannot be accessed without The Hidden Treasure of Area Zero.
How to View and Assign Marks
- Select a Pokémon in your party or your Boxes, then select Check summary.
- From the Pokémon Status Summary screen, navigate left or right to the Memories screen.
- If the Pokémon you are viewing has a mark but is not currently displaying a title, Assign a Ribbon or Mark will be shown on the right. Press the A Button, and you can assign a mark to the Pokémon and display the associated title.
Enjoy basking in the moonlight as you catch lots of Clefairy, Trainers!
