It's time to pick up the pace and duel a character in Fortnite for some much-needed experience.Week 15 Challenges pic.twitter.com/xY29ZoXH0L— iFireMonkey (@iFireMonkey) February 16, 2021There are five stages to the challenge, and opponents may be challenged in any order the player sees fit. The fastest way would be to go straight from the battle bus to the challenge location. However, it's always a good idea to find good loot as the NPCs are often bullet sponges.Once the challenge has been completed, players can exit the current game, restart, and go for the next opponent. There are eight NPCs that can be dueled in-game, and they are scattered around in Fortnite.Players may initially find it hard to duel a character in Fortnite, as they are scattered around the map and other players are always on the prowl, looking to complete the same challenge or simply making it harder by third-partying a fight.However, with a bit of luck, patience, good timing, and top-tier loot, players should have no problem completing Week 15 Challenges. Winning 25 duels is worth a staggering 143,000 experience points, which would be worth a lot for anyone wanting to level up the battle pass for the final rewards.Locations where players can duel a character in FortniteSome locations can be tricky to reach, while others are relatively easy and secluded from landing hotspots.
