Odd Keystone: Difference between revisions

The Odd Keystone (Japanese: かなめいし Keystone) is an item used in the Generation IV games to summon Spiritomb.

Odd Keystones act like containers, capable of trapping and binding Spiritomb inside themselves. All Spiritomb use them as a base.

In the games

An Odd Keystone in the Underground

In Pokémon Diamond, Pearl, and Platinum, they can be found by digging in the Sinnoh Underground, and one can be found with the Dowsing Machine in Twinleaf Town. A Black Belt just west of Hearthome City hands one to the player, indicating not to ask questions about it, before describing the procedure to summon Spiritomb.

The procedure is as follows. The player must take the Odd Keystone to the broken-down tower on Route 209 and place it there. After this, the player must go underground and talk to 32 other players, and after having returned to the surface, Spiritomb will appear the next time they inspect the Hallowed Tower.

Though the technical requirement is to talk to 32 people, the player needs only to talk to one person 32 times, either leaving the Underground after each time or entering and exiting their Secret Base using the "close door and decorate" function, for it to count separately for both players.

Once placed in Hallowed Tower, the player can check the Odd Keystone every now and then to get an idea of their progress towards unlocking Spiritomb. Progress is indicated by gradually changing responses from checking the Keystone; the responses change as the player talks to more people Underground.

In Pokémon Black 2 and White 2, it can be obtained from one specific antique shop variant in Join Avenue. To obtain in any other game, the Odd Keystone must be traded from within said game's respective generation.

Outside of Pokémon Diamond, Pearl, and Platinum, its only use is to be sold, either for $1050 normally or $3000 when sold to the item maniac in Icirrus City.
