Here is a very usefull tip to everyone

[Nexen57]

So you'll need to catch a Drampa and a Machoke. You know that after winning against Erik and Souta you have access to use respectively Strength and Fly outside of battle.

But you can't have those HMs until the next chapter especially the Strength HM because you get it while you are blocked from leaving GDC so you'll have to wait until you can use Fly to use it to fly to previous locations.

 

But there is a solution to this.

When Machoke evolves into Machamp(with a Link Heart), it learns Strength and it actually works outside of battle after you get Erick's badge.

So with this trick you can get for example Gastly or Sneasel or Dusknoir because the Reaper Cloth is locked between Strength boulders just after Erick which is a BIG time difference between the time you can get Fly.

 

Also Drampa learns Fly at lvl 50 so you can use it just after beating Souta which is at the end of Chapter 12 and you get the Fly HM just before the end of Chapter 13 which is a smaller time length than the one with Strength.It is usefull for getting mons that are locked because you need items that are found in GDC like Blast powder with Ralts and Charmander or Starly because of the Mosely quest.

Or you can get a Golden Wing and a Golden Gauntlet in the AP Shop

The Golden items need both the HM in your inventory and the badge to work so you can't use them.

The use of strength with Machamp like that is an oversight that will be fixed in future versions.
