Fortnite Chapter 6, Season 1 introduces Sprites, ethereal beings offering players helpful items and abilities. The Earth Sprite, the most beneficial but elusive Sprite, is found only on the new Chapter 6 map in Battle Royale, Zero Build, and Ranked modes.
Earth Sprite Locations:
The Earth Sprite boasts nearly two dozen potential spawn points, each marked by a distinctive solitary lantern (similar to the one shown in the image below). However, only two Sprites appear per match, necessitating a search across multiple locations.


The above map, courtesy of Perfect Score on YouTube, pinpoints all 22 possible Earth Sprite locations:
Giving Weapons to the Earth Sprite:
Locating the Sprite is the challenge. Once found, simply interact with it (using the interact button) while holding a weapon. This completes the Week 1 Quest, rewarding you with 25,000 XP. Note: the weapon you offer will be lost, but replaced with a random Legendary weapon.
Fortnite is available on various platforms, including Meta Quest 2 and 3.
