Where do you find arceus in Pokemon pearl?

Answer 1

I won't guarentee that this will work for everyone. This is just what happened to me. Do not need an AR.

This happened to me unintentionally... I don't know if it was just a fluke or if it happens every time... when you first encounter Palkia defeat it. Don't catch it! Later on Lucas or Dawn whichever one isn't your character will run up and say that Palkia is back and on a rampage again. Before you go back to Palkia, gather the psychic trio Azelf, Uxie, and Mesprit... Take those three to where Palkia is waiting at the top of Mt Coronet. You can catch Palkia then and after that you can go into a pokemart and find the man in green that will give you the Azure Flute. Take that to the top of Mt. Coronet and you will be asked to activate it... the rest is pretty obvious...

Ok. That sound like a fluke. Did you do the wifi event and just forget? Because that's how you get the Azure flute. And are you sure that you, without knowing, did a cheat? Because defeating Plakia is risky thing. I say just get the Azure flute, or trade with someone.

PS. Do you think it would work for Pokemon Diamond?
