How do you get a Spirtitomb in Black 2?

Question

I need it.... RIGHT NOW

Answer 1

>Black 2 White 2
One
Trade in Nimbasa City

It's the dropped item event. You speak to either Yancy/ Curtis, and after enough calls they will offer to trade with you.

Also, you can't find Spiritomb in Dream World if you use a B2W2 account; you need use a BW account to find one in DW. So if you have a previous game, then you could transfer one. Otherwise, Yancy/ Curtis is the only way to get a Spiritomb in game.

Trading with another player is the other option.

Spiritomb

Dropped Item event

Answer 2

You can get one in Nimbasa city by trading with a person, the only other way would be to poketransfer one from diamond, pearl or platinum
