am after a spiritomb but ii dont know how to put the odd keystone into the hallowed tower am i jus been thick here or is there a certainway it jus says been build many years grrrrr

...I'm tired of saying this but the "DPP Questions" Thread ( "Diamond/Pearl/Platinum Q&A [ALL QUESTIONS HERE]" ) is where this goes & second...

First, you put to key into the tower which you probably already did by examining the tower & using the "Odd Keystone" on it as prompted to...
Second, you need to have meet 32 people inside their respective Underground Base meaning go in to their base & just talk to the person...it can be the same person 32 times or however you want to do it.
Third, afterwards you go back to the tower & save in front of it first & then examine again to initiate the encounter, catch the Spiritomb & success, you now have Spiritomb...

Hope this helps...

Stop insulting people for putting stuff in the wrong place, they are asking a simple and polite question, and you're just being rude in return.

Btw, i'm not too sure about the Spiritomb, I have put the Odd Keystone in the Hallwoed Tower, but I still don't have one, I dn't really understand how this works.

lol. after putting in the odd keystone, you have to talk to something like 33 people in the underground, then you can catch spiritomb. i havent tried it myself, but im pretty sure it goes something like that. XD of course, you could check the psypoke database, or serebii, or just plain google it.

I think 32 people is crazy. I don't even have that many friends.

@Ryanh181
I don't have any. xD

It can be the same person each time.
