Were Do I Get The Lustrous Orb In Pokemon Diamond?
You can't but the ar code is497816
You can't get the lustrous orb in pokemon diamond but you can in pokemon pearl:after you catch palkia instead of going out keep on going up until you see an item ball witch is a lustrous orb,you can do the same on pokemon diamond but instead you get an adamant orb
I heard this of a page to get a mew if you go to the place where the luster orb is on diamond mew would be there
You cannot get lustrous orb in diamond only platinum or pearl I think.
