orbs are basicaly a ghost that you see as a floating white orb. You can find them easily in photos from haunted locations. You may find some randomly too. I'm not sure if its possible to see orbs with the naked eye though (without some kind of ability)
You find Shadow Orbs at the bottom of the long, deep 'Corruption' shafts.
first you need to complete the game, then find orbs, or you can find orbs first it doesn't matter, then you buy it at the secrets menu.
The orbs are rare drops from the Legacy bosses, you have to keep fighting them over and over.
Go to marrowak training dungeon. All you find there is escape orbs and money, also you dont lose the items you have if you die!
find orbs in the road to spear pillar
You must of already have Palkia or Dialga because you're supposed to find those orbs after you verse them.
They basically give up the team.
on top of mnt pyre
you can only get them when you beat the sinnoh dex i accedentily sold the orbs the same day i found out you need them to battle dialga and palkia. p.s. that rock in there, the front of it holds a stone plate.
Sending Orbs was created in 2004.
