Pokémon Brilliant Diamond and Shining Pearl are out on Nintendo Switch, and for fans eager to jump back into the Sinnoh region, there are a few favourites they’ll be keen to pick up straight away. There are also plenty of legendary Pokémon to catch, although some of more difficult than others.
In this guide, we’ll show you how to get Cresselia in Pokémon Brilliant Diamond and Shining Pearl.
How to get Cresselia in Pokémon Brilliant Diamond and Shining Pearl
Complete the Sinnoh Dex
Firstly, you’ll need to complete the Sinnoh Pokédex. Thankfully, this can be done with one copy of the game, and in one playthrough. All you need to do is to see one of every Pokémon, not catch them, and this can all be achieved during the course of the normal game.
If you’re struggling to see the box legendary of the other copy, Dialga or Palkia, speak to Cynthia’s grandmother and she’ll show you it.
After that, head back to Professor Rowan and he’ll upgrade your Pokédex for you, allowing you to catch almost 500 Pokémon in total, including plenty of new legendaries.
Canalave City / Fullmoon Island
Head to Canalave City and speak to the sick boy and his mother in the house in the bottom left corner. After you do this, speak to the sailor outside and he’ll take you to Fullmoon Island.
Once there, you’ll speak to Cresselia before it flies away.
Like many legendaries in the past, Cresselia is a roaming Pokémon. This means when you fly, it’ll move locations, and you need to track it down on foot or on bike, or get extremely lucky and run into it. You can do this by using the marking map on your Pokétch which is given to you in Jubilife City.
Once you’ve found Cresselia, you’re going to need to stop it from escaping. Freeze or Hypnotize the Pokémon to stop it from fleeing from battle, and after that, it’s just like any wild Pokémon encounter.
