The Odd Keystone is one of many hidden items throughout the Sinnoh region of Pokémon Brilliant Diamond and Shining Pearl. This item, hidden in plain sight, is excruciatingly easy to locate if you know where to look. This item will lead you to Spiritomb in the end.
Where to Find the Odd Keystone in Pokémon Brilliant Diamond and Shining Pearl?
Following Route 208 just before entering Hearthome City will lead you to the Odd Keystone. Mount Coronet is also east of it.
On the bottom right of the screen, once you’ve reached a patch of grass to the left of the Route 208 sign, you’ll see a martial artist.
He’s tucked away behind some obnoxious trees. He’ll give you the Odd Keystone if you talk to him.
He then directs you to Route 209, where you will find the Grand Underground. The Odd Keystone is used to prevent a stone tower from collapsing in the area.
But first, you must locate the Hallow Tower, which is located on Route 209 just south of Solaceon Town. It will ask you to use the Odd Keystone once you touch it.
Once you’re down there, the martial artist tells you to listen to the stone pillar. Hearthome City is located east of Route 209.
Use the Explorer Kit in your bag’s “Key Items Pocket” if you’ve forgotten how to go underground. When you get to the subway, talk to 32 different NPCs or 32 online players.
Return to the Hallow Tower once that task is completed. The battle with Spiritomb will then begin.
If you save before this encounter, you’ll have a better chance of catching the mysterious Pokémon. Stock up on Pokéballs as well.
