In this guide, you will come to know how to use Shadow Stone or Flopper to phase for three seconds near a player in Fortnite.
You have to land between the Weeping Woods and Holly Hedges to complete the quest, as shown in the map below.
When you land at this location, you can easily find shadow stones everywhere. You also have to pick up a gun or anything to fight with; when you get close to the shadow stone, you have to consume it.
You can also find the shadow fish, which will turn you into a ghost. Once you are a ghost, you have to find other players and go closer to them for only three seconds. You can also use the controls located on the bottom of the screen, and if you are using a computer, you have to press the right click button from the mouse to face through walls and roofs, make sure that the other players won’t kill you.
