In this episode, Earth is introduced to a new status effect called "Break Arms," which prevents players from wielding weapons if their arms are severely injured. Additionally, he learns about the opening of a new dungeon called "A Challenge From the Departed," a labyrinth of randomly generated levels filled with traps and monsters where players must reach the tenth floor within one hour.

To prepare for the dungeon, Earth crafts a new composite bow based on real-world designs, as well as a unique shield that can transform into a bow, ensuring he retains long-range combat capabilities even if affected by the "Break Arms" effect. His innovative craftsmanship provides him with a powerful weapon tailored to his specific needs.

Upon entering the new dungeon, Earth is approached by a group of players calling themselves the "One More Rangers." They are missing a member and invite Earth to join them. Despite their eccentric roleplaying, they prove to be competent, and Earth aids them with his "Threat Detection" ability to navigate the dungeon's traps.

The team encounters various monsters, including wizards and skeleton soldiers, which must be defeated using different strategies. Earth's new aeolian dust arrow proves effective against the gnomes, demonstrating his readiness for the dungeon's challenges.

The episode reaches its climax when Earth and the Rangers assist another group trapped in a room filled with traps. Thanks to Earth's quick thinking and the Rangers' combat skills, they manage to defeat the monsters. However, Earth warns the other group not to open a treasure chest he identifies as a trap, showcasing his thief abilities.

After clearing the dungeon, Earth continues his crafting efforts and, with the help of a skilled blacksmith, creates a specialized tool for more effective trap disarming. The Fairy Queen makes an appearance, humorously misunderstanding the nature of her relationship with Earth, and he obliges her request for comfort after a tiring day of distributing contract crystals to new players.
