This Fortnite challenge is part of the TNTina’s Trial Challenges, the second agent that Chapter 2 Season 2 focuses on. To complete it, you'll have to use a total of five decoy grenades. This challenge is relatively simple since you can do it all in one go. Introduced at the launch of Chapter 2 Season 2, the Decoy Grenade is a Rare item that comes in stacks of three.
We'll be able to find it everywhere, on the ground or in chests.
Its effect is quite interesting and can be confusing, especially for beginners. Upon activation, the grenade will generate a cloud of smoke and a moving clone of your avatar. Experienced players won't be fooled but this item is still fun to use.
Note that the challenge also works in Team Rumble, where you can find the grenades in question extremely easily.
