This Legendary Fortnite challenge is likely to be one of the toughest to complete, purely on the basis of the location.
Head to the centre of the map marked below, where you'll find purple crystals.
Where to find Zero Point crystals
Breaking them will release fragments, which you can pick up and consume. For a short time afterwards, you will be able to perform a dash.
Simply dash towards an enemy and make sure you deal damage within ten seconds of the dash to complete the challenge.
Players are likely to hotdrop the location, so be prepared for a fight. There are multiple stages to this quest, so for that reason we recommend doing this one in Team Rumble mode.
That way, you'll respawn repeatedly, and save time starting new games.
