Pokemon BDSP: How to get Arceus and Darkrai
Two other mythical Pokemon will appear in Pokemon Brilliant Diamond and Shining Pearl (BDSP). After downloading the game's newly released 1.3.0 update, you'll be able to get items from your encounter with Arceus and Darkrai, your first chance to get them in the remake. Here's what you need to do to catch two fabulous Pokemon.
Before encountering Arceus in Pokemon BDSP, you will first need to enter the Hall of Fame and obtain the National Pokédex in the remake, as well as clear all the main story missions in Pokemon Legends: Arceus.
After meeting these requirements, head back to your bedroom in Twinleaf Town and get Azure Flute. Bring the item to Spear Pillar atop Mount Coronet and you'll trigger an encounter with Arceus.
How to catch Darkrai
To meet Darkrai, you'll need the Member Card, which will be distributed via Mystery Gifts from April 1st to April 30th. After getting your Member Card, head to Newmoon Island and you'll have a chance to capture Darkrai.
Like Arceus, you first need to be in the Hall of Fame and get the National Pokédex in Brilliant Diamond/Shining Pearl before you can meet Darkrai. You also need to travel to Fullmoon Island and encounter Cresselia.
The 1.3.0 of Pokemon BDSP has been updated. In addition to Arceus and Darkrai, the update introduces the Global Wonder Station, a facility located in Jubilife City where you can trade wonders with players around the world. You can buy them at PKMBuy.com.
