How do you evolve dusclops in mystery dungeon 2?

Answer:

You need to have a Link Cable (an in-game item) if it normally requires trade to evolve and a Reaper's Cloth. You also need to Have Recruited Darkrai, Cresselia, Palkia (questionable), and brought back Mananphy (?). Then you should be able to evolve your Pokemon at a special Route.
