so you can catch spirittomb at level 25
You can't. The Odd Keystone is only obtainable in Diamond, Pearl and Platinum. You will need to trade a Pokemon with an Odd Keystone to get it on SoulSilver.
there are 2 ways u can get the keystone mining underground or at route 208 talk to the fighter close to the honey tree
You walk up to the crumbled tower and press "A" and it will say the odd keystone looks like it will fit.
jusat go to it and click A by poke master rydhan
You don't need cheats. After you get an odd keystone, go to the ruin on Route 209 and place the keystone in. Then go talk to 32 people underground (use wireless communication). Then go back to the ruin and interact with it, and you will start battling a spiritomb.
the name of the episode is The Keystone Pops!. it is the 56th episode of the Diamond and Pearl Series :3
A spiritomb will apear unless you hav'ent met 32people in the underground.
You can get a Spiritomb after you insert the Odd Keystone into the broken tower (Hallowed Tower) and talked to 32 people underground.
To get the Odd Keystone in Pokemon Diamond, you must go to Route 208, where there is also a Berry Master that gives you Berries, daily. You can also receive a Poketch App from the Little Girl in the house. Along with the two Trainers in that Route, William and Hannah, there is a man with a red-coloured headband, who looks like the Karate Trainers. If you go talk to him, he will give you the Odd Keystone, which you can use to help you get the Pokemon Spiritomb if you restore the tower on Route 209.
you get a spirttomb by talking to people underground 32 times. P.S this will take a long time
you need another ds and diamond, then trad the Pokemon to pearl. jay17
you need to hatch a togepi in soulsilver or heartgold then trade it to pokemon diamond
