To complete this challenge belonging to the Storm Racer Mission of Season 10 in Fortnite. You need to visit the very centre of storms to find a light beam. The beam is purple and has a lightning symbol at its base.
Get close enough to the flash to make the beam disappeared, meaning that the first step is validated and you can move on to the next one.
In Fortnite, the storm formed nine circles before closing completely. The player is offered nine opportunities to complete the challenge that only requires you to go to the center of three circles.
Of course, you are advised to focus on the first three circles. Going to the centre of the last circles in front of your opponents can be particularly dangerous...
Don't forget that the challenge must be finished in one single match, so there's no way you're leaving the game until you've gone through three circles!
