The ones that waited for God, the Creator of all Pokemon to come in the newest Pokemon additions, Pokemon Brilliant Diamond and Pokemon Shining Pearl, will be pleased to know that the almighty Pokemon is now available.
To have Arceus in Pokemon Brilliant Diamond and Pokemon Shining Pearl, firstly you must have the Pokemon Legends: Arceus save file, with every single main mission completed. There are 27 main missions in total. The second thing you need is to enter the Hall of Fame and get the National Pokedex. Keep in mind that Arceus is part of an in-game event, but the good thing is that the event is not time-limited.
Once you get these items, return to your room in either Pokemon game (Brilliant Diamond or Shining Pearl). There you will see the Azure Flute item, which is very important in getting Arceus. The next step is to go to the Spear Pillar (found at the top of Mount Coronet, and there you will find the almighty Arceus (if it decides to reveal itself to you). You must engage in a battle with the Pokemon of all Pokemon. But you might get a Shiny Arceus if you win the battle.
Have you gotten Arceus yet? Can you describe the feeling of seeing the one-of-a-kind Pokemon for the first time?
