How do you use an odd keystone in pokemon pearl?
You place the odd keystone in the stone tower east of Hearthome city [South of Soleceon Town] and go under ground and speak to 32 people. Hiker do not count but you can go under ground [use the explorer kit] with a friend(s), talk to them, go back up go down again and speak to your friend(s). Repeat this as many times as needed. Once you do this, go back to the tower and press ‘A’ at it. Spiritomb will appear and you can catch it. Good luck!
