Where To Get The Lustrous Orb To Change Giratina Form In Pokemon Platinum?

The lustrous orb is not Giratina's orb it's Palkia's.What your looking for is the Griseous orb and you find in the back of turn back cave in sendoff spring in spring path.If you beat or ran from Giratina on your fist battle then it's at the back of the cave if you caught it then there's a portal at the back go in the portal and look for a poke ball inside that poke ball is the orb.

You have to go back in the portal where you found giratina

At the turn back cave where you catch giratina on diamond.Poo out

Lustrous orb does not change giratina's form.. The griseous orb does. .

You can't change giratina with a lustrous orb sorry but go to the Portal then you found this poke ball click on it then it some orb!
Hope it helps! :)

On platinum go through the turn back cave mouth where Cynthia leaves you and go through hope it helps:)

You go to the lake north of the hotel near Sunyshore City. There, you'll find a cave. In it, after a lot of searching and going back to the start (that's why it's called the turnback cave) you'll find the GRISEOUS Orb (because this one is for Giratina, not the Lustrous orb, which is for Palkia).

Go to turn back caves idiots

Go to spring path go in the cave go through eny passage in till you find the portal and behind the portal you will find the orb

Firstly, its called the griseous orb. Lustrous orb is for palkia and adamant is for dialga.
It is found through turnback cave in the distortion world, there is only one route to it and only it is there. So its easy to find :3

Go trade from platinum a-holes!

Trade palkia from any pokemon game and he will have the lustrus orb

You go back to where you caught him and go into the portal and get the orb
