Update 2: Following the delay below, the distribution of the Galarica Wreath – an item needed to evolve a Galaric Slowpoke into a Galaric Slowking – has been in Pokémon Sword and Shield for a very limited time. You can get the article by entering code CR0WNF1NALS on the Mystery Gift screen in the game.
The code will only be valid tomorrow, Sunday 7 February (14:59 UTC) (thanks, Serebii). This is 06:59 PT / 09:59 ET / 15:59 CET.
Update 1: Unfortunately, Serebii reports that the tournament final during which the special code is scheduled to be distributed has been delayed, which means it may take a while before you can get your hands on the free Galarica wreath:
Original Article (Friday 11 December 2020 14:30 GMT): Next week, Pokémon sword and shield players will easily be able to find one of the more awkward items in the game.
During the South Korean Pokémon Sword and Shield Crown tournament, which will be broadcast live online, a distribution code will be released giving players one Galarica wreath. This special item is the only way to evolve a Galarian Slowpoke into a Galarian Slowking, so collectors and Pokédex complete will want to grab it while they can.
Serebii reports that the code “will only last 24 hours from the start of the event until 14:59 UTC on December 20.” Codes are not regionally bound, so you will be able to get the Galarica wreath no matter where you are based once the code is shared.
It’s worth pointing out that you can get a Galarica wreath in the game without using a special code, but it’s one of the more time consuming items to get. To get one, you must find no less than 15 Galarica twigs – an already relatively rare object itself – and hand them over to an NPC in The Crown Tundra’s Roaring-Sea Caves. If you are struggling to find it, this is an excellent opportunity to speed up the process.
