I'm at the part where the magnemite drops the disk in mount snowfall and gengar is blocking your way and you have to give him a duskull lamp... how the heck do you get a duskull lamp?

 

[Shiny Pichu]

Leave the Ruins of Truth and go to Springleaf Field. Say "hi" to the Duskull. Answer the question correctly. Instead of a Nice Card or P10 you will receive the Duskull lamp.

I think he'll give you a Nice Card before he gives you the lamp thing.
