It is in the Safari Zone when you put different items in a area.
Trade it while it is holding the reaper cloth.
Dusclops uses it to evolve into Dusknoir. Equip a Dusclops with the Reaper Cloth, and then trade it to initiate the evolution.
You add objects to the Safari Zone. Such as Forest objects with the Mountain area. You'll need to wait a few days to get it.
You just have to level up Duskull to level 37 into Dusclops.
You can find dusclops in turn back cave.
In the Safari Zone (mountain) with 18 Forest objects after 20 days.
it doesnt evolve by level.give it the reaper cloth and trade.
Go to rout 224 and use the pokeradar that's how i got my dusclops.
you don,t find them in the wild. you can only evolve duskull into dusclops. there. But in the history of R/S/E you can get dusclops. you can,t get dusknoir.......... ONLY WITH A GAME SHARK OR 3rd PARTY DEVICE.

Lv 40 to evolve into Dusclops. Evolve Dusclops by giving it the Reaper's Cloth (Google to find where that is) and trade.
Give Dusclops the reaper cloth and trade him. He evolves into Dusknor (I think that's how you spell it)
