you evolve duskull then when it has evolve trade it holding reaper cloth
dusknoir is only in gen 4. diamond, pearl, etc.
face dusknior and keep using your best move eat something if you hp is low like a oran berry the others will take care of the sableye. (be careful your next opponent to fight is primal dialga)
You Must givedusk lops the reaper cloth and trade him then he will evolve to dusknior
If held by Dusclops, it will evolve into Dusknoir when traded. Otherwise it has no use except to sell.
Dusknoir is a bit difficult to find. First go to Noir Forest, you will notice the Dusclops lurking around. If they spot you you will be sent back to the entrance so , carefully sneak up behind them and capture them all(Make sure you have no other party pokémon you wish to keep) .Once every one of them are captured Dusknoir will appear. Then its capture time once more. :D
