How to Use Defog

Defeat Crasher Wake to Use Defog

Before you can use Defog, you'll need to defeat Crasher Wake at the Pastoria City Gym first. He specializes in Water Pokemon. We recommend having an Electric type Pokemon like Luxray and a Grass type Pokemon like Roserade in your team before fighting Crasher Wake.

How to Beat Crasher Wake

Use Poketch in Foggy Areas

To use Defog, press the R button to open Poketch. If the Poketch app does not appear in the upper right corner of the screen, press the R button twice. If a small screen is displayed, press the R button once to enlarge it.

Once the Poketch app is displayed, press the red button to switch to the Hidden Moves screen and select Defog from the menu.

Where to Use Defog

Used on Route 210 on the way to Celestic Town

Defog is required to access the northern side of Route 210 leading to Celestic Town. You can proceed without using it, but it is recommended to return to Great Marsh to pick it up from the Ace Trainer.

Used on Mt. Coronet to reach Snowpoint City

You also need to use Defog in Mt. Coronet to reach Snowpoint City. When you enter the cave and go down on the first set of stairs, the screen will turn white. Use Defog from the Poketch app to remove the fog.

Used on Route 224 after entering the Hall of Fame

Defog is also required to access Route 224 after entering the Hall of Fame. Keep in mind that this is the route that allows you to access the Flower Paradise and catch Shaymin.
