Effect

Pokémon Diamond, Pearl, Platinum, Brilliant Diamond, and Shining Pearl

InPokémon Diamond, Pearl, andPlatinum andPokémon Brilliant Diamond and Shining Pearl, an Odd Keystone can be placed in theHallowed Tower, which is located onRoute 209 in theSinnohregion. This item has no use in other regions.

If the player talks to 32 or more other players in the SinnohUnderground^DPPt/32 or moreNPCs in theGrand Underground^BDSP after placing the Odd Keystone, a wildSpiritomb will be encountered the next time the player inspects the Hallowed Tower.

In Pokémon Diamond, Pearl, and Platinum, while in theory it is necessary to talk to 32 different players, in practice another player can be counted twice as long as the player themselves leaves the Underground or enters theirSecret Base using the "close door and decorate" function between the interactions; this potentially allows a player to encounter Spiritomb by interacting with the same player 32 times.

Once placed inHallowed Tower, the player can check the Odd Keystone to track their progress. The message gradually changes as the player interacts with more players in the Underground.

Pokémon Legends: Arceus

InPokémon Legends: Arceus, after the player obtains the Odd Keystone fromVessa, they are tasked to find 107wisps throughoutHisui. The number of wisps collected is shown on the Odd Keystone in thesatchel. After the 107 wisps are found and the player talks to Vessa again, the player is tasked to go to theShrouded Ruins to find Vessa and the final wisp. After the final wisp is found, the Odd Keystone disappears, and upon interacting with the mysterious statue in the shape of the Odd Keystone, the player can encounter Spiritomb.
