I Don't know just try yourself ^^
Mt. Cournet entrance on yellow plate it will say whether you want to blow the Azure Flute or not! (I haven't done this but I saw Marriland.com do it)
To get Dialga in Soul Silver you must first trade over Arceus from a different game. Then with Arceus in the front of your party go into the building in the Ruins of Alph. You will then experience some wierd things and you will be at the Sinjoh Ruins. Exit and follow the hiker. When you are at the cabin put all your Pokemon except for Arceus in the PC. Talk to Cinthia. Then go back to the Sinjoh Ruins. Talk to Cinthia again and you will have the choice of getting Dialga, Palkia, or Giratina.
I've gone back 4 times. It's rock climb. Trust me.
In fact, there is no other way to Sunnyshore city other than that of going to Spear Pillar and coming back. Then, he is gone.
after you beat the game, you have to go back to spear pillar and find the adamant orb and the lustrous orb. (ACTUALLY they are in the cave with a waterfall) you have to catch heatran first and you should also have the national dex. then you keep going until you reach the spear pillar and when you go in, you will find a blue diamond shaped portal and it will take you into a battle with dialga. To get Palkia, just go out of Spear Pillar and walk in again and there will be a pink portal. there are videos you can watch on youtube to see. http://www.youtube.com/watch?v=aRFP4EwpZ8c http://www.youtube.com/watch?v=3E-iAypOCvw&feature=related (the part in ( ) are from a different person)
you can but its a waste of time unless you use the action replay to get the azure flute to get arceus
You need the Azure Flute go back to the top of Spear Pillar then play it (only do this when you've defeated Dialga/Palkia).
You use it and it should make a staircase. Walk up the staircase and walk to the back. There is Arceus at Level 70, be ready to fight it.
First off, your technically still in mount coronet when your at spear pillar, so you can't fly. And second of all, you exit spear pillar the way you came and go back into mount coronet (the way that you came into spear pillar). If you have an escape rope, I'd recommend using it.
go back to spear pillar
Arceus - Supposedly it shaped the galaxy in the game. You can catch him by going to a Pokemon event or using and A.R. to get an Azure Flute. Go back to Spear Pillar where you go to the distortion world and the flute will make noise. Some stairs will appear taking you up to Arceus...
yes you can.
After you catch/defeat Dialga go back in to Mt. Coronet and come back out to the spear pillar you will then see the pink portal to catch Palkia at Lv.70, good luck!
First you have to get an Azure flute from a guy in a green cloak in the pastoria citys Pokemon mart. (He isn't always there). Then you have to go back to Spear Pillar and it asks you if you want to play the flute. Say yea. Then stairs will appear. Go up the stairs and you will see Arceus.
Arceus is in the hall of origins directly above spear pillar you will need the azelf flute(event item) to make the stair case appear that leads to arceus(not easy to get)You had to get Arceus in an event. The event already ended so maybe you can get some codes.(I don't know any codes) Or you can trade with someone else who has Arceus. Then you can get to The Ruins of Alph and get Palkia, Dialga, or Girantina with Adament orb. Then you can trade back(unless you're keeping it)
go back to spear pillar (where you battle palkia/dialga) and step on a symbol in front of the entrance you wil be asked to blow the azure flute select yes and stairs will appear go through that stairs and you will find arceus good luck (I still have a master ball so I am lucky)
To leave spear pillar all you have to do is go inside mt. corenet then use an escape rope if you cant then just go through back to the beginning or you might be able to fly i forget.
