For this Fortnite challenge, you'll need to get your hands on a Rift. It's a simple enough task, but locating NPCs can sometimes be tricky.
Here's where you need to go.
Where to find Rift-selling NPCs
There are actually other characters who sell Rifts, but their spawns can be a little random. Some Jonesy characters sell these mobility items, but they only appear in certain areas.
As such, we strongly recommend that you stick to these two spawns above, to ensure the challenge is completed quickly.
Note that using a Rift with these characters 245 Gold Bars. Make sure you have farmed the area a bit before embarking on this challenge.
Once activated, the Rift will teleport you and all of your allies into the air. You can then redeploy your glider as you wish -- handy for running away!
As usual, you can quickly find the NPCs thanks to the speech bubble that appears on your map and in the game. Finally, be careful not to attack the characters who sell Rifts -- once provoked, they become hostile and attack you, and you won't be able to interact with them again.
