Key takeaways

Keep these points in mind before entering the ruins.

  • Return after Regional Phenomena The four monolith riddles are accessible only after the main Regional Phenomena quests have been completed. If the investigation does not progress, confirm that prerequisite before searching for a solution.
  • Use all four Sage abilities Each riddle is tied to the elemental ability of one of the four Sages. The quest is designed around applying the correct ability to a puzzle in the ruins rather than simply examining the monoliths.
  • Search below the stone slabs A successful solution reveals a hidden chest beneath a stone slab. Check the newly opened area after each riddle instead of moving on immediately.
  • The final reward is the Dusk Claymore Completing the entire investigation grants the Dusk Claymore along with a valuable reward package. The weapon is tied to finishing the full sequence rather than to solving only one riddle.

Investigate the Thyphlo Ruins overview

Investigate the Thyphlo Ruins is a post-Regional Phenomena side adventure built around four Sage-powered riddles.

Investigate the Thyphlo Ruins begins when Link speaks with Kazul, a researcher stationed in a tent near Thyphlo Ruins Skyview Tower. The investigation centers on a group of monoliths within the ruins. Their riddles are not ordinary written puzzles: each one points toward a task that must be completed with the elemental ability associated with one of the four Sages.

The four tasks are titled The Owl Protected by Dragons, The Corridor Between Two Dragons, The Six Dragons, and The Long Dragon. They become accessible only after the main Regional Phenomena quests have been completed, so the investigation is intended for a later stage of the adventure rather than as an early exploration activity. The quest therefore rewards players who return to Thyphlo Ruins after assembling the full set of Sage abilities.

Each solved riddle reveals a hidden chest beneath a stone slab. Completing the investigation also grants the Dusk Claymore, making the quest valuable both as a lore discovery and as an equipment reward. The monoliths describe the ruins as a place built to honor the king and sages who defended Hyrule against the Demon King, giving the puzzle sequence a historical purpose beyond its mechanical challenges.

Walkthrough

  1. 01

    Unlock access to the four riddles

    Confirm that Regional Phenomena is complete

    Before travelling to the ruins, make sure the main Regional Phenomena quests have been completed. The monolith riddles are locked behind this progression, so searching for their solutions early will not advance the investigation.

    Location: Hyrule

    TipTreat this as a return-visit quest rather than an early Thyphlo Ruins activity.

  2. 02

    Start the side adventure

    Find Kazul's tent

    Travel to the area near Thyphlo Ruins Skyview Tower and look for the tent occupied by Kazul. Speak with the researcher there to initiate Investigate the Thyphlo Ruins and learn why the monoliths require further examination.

    Location: Near Thyphlo Ruins Skyview Tower

  3. 03

    Identify the four tasks

    Read the monolith clues

    Examine the monoliths in the ruins and note the names of the four tasks they describe. The important division is by riddle: The Owl Protected by Dragons, The Corridor Between Two Dragons, The Six Dragons, and The Long Dragon each represents a separate objective.

    Location: Thyphlo Ruins

    Watch outDo not assume that one solved monolith completes the investigation; the quest requires all four tasks.

  4. 04

    Complete The Owl Protected by Dragons

    Solve The Owl Protected by Dragons

    Use the elemental ability of the appropriate Sage to address the puzzle indicated by The Owl Protected by Dragons. The riddle is one of four separate trials, so continue checking the ruin area after the ability has been applied and the puzzle registers as solved.

    Location: Thyphlo Ruins

    TipIf the puzzle does not respond, reassess which Sage ability the riddle is describing instead of repeatedly interacting with the monolith.

  5. 05

    Complete The Corridor Between Two Dragons

    Solve The Corridor Between Two Dragons

    Follow the clue for The Corridor Between Two Dragons and apply the corresponding Sage's elemental ability to the puzzle in the ruins. Completion is confirmed by the appearance of a hidden chest beneath a stone slab, which should be collected before leaving the area.

    Location: Thyphlo Ruins

    Watch outThe chest is part of the reward for solving the riddle; search below the revealed stone slab rather than assuming the objective ends at the puzzle.

  6. 06

    Complete The Six Dragons

    Solve The Six Dragons

    Investigate the area described by The Six Dragons and use the matching Sage ability to complete its elemental puzzle. As with the other riddles, the solution exposes a chest beneath a stone slab, so inspect the newly opened space once the task is finished.

    Location: Thyphlo Ruins

    TipKeep the four riddle names separate in your notes; each title refers to a distinct task rather than a step in one repeated puzzle.

  7. 07

    Complete The Long Dragon

    Solve The Long Dragon

    Complete The Long Dragon by using the elemental ability of the Sage associated with its clue. When the puzzle is solved, look beneath the revealed stone slab and collect the hidden chest before moving on to the final quest completion.

    Location: Thyphlo Ruins

    Watch outThe investigation remains unfinished until this fourth named task has also been solved.

  8. 08

    Finish Investigate the Thyphlo Ruins

    Collect the investigation rewards

    After all four riddles have been completed, collect the rewards from the revealed chests and finish the investigation. The complete quest grants the Dusk Claymore, so verify that the full sequence has concluded before leaving Thyphlo Ruins.

    Location: Thyphlo Ruins

Mission mechanics

The central mechanic is matching each monolith riddle to one of the four Sages' elemental abilities. This makes the quest dependent on story progression: the required abilities are not merely helpful tools, but the intended means of interacting with the four puzzles scattered through Thyphlo Ruins.

The riddles are organized as four named challenges rather than one continuous encounter. The Owl Protected by Dragons, The Corridor Between Two Dragons, The Six Dragons, and The Long Dragon must each be solved independently, and the discovery of a hidden chest beneath a stone slab signals that a corresponding puzzle has been completed.

The quest also works as environmental storytelling. The monoliths explain that Thyphlo Ruins were built to honor the king and sages who defended Hyrule against the Demon King, so reading the clues connects the mechanical puzzle sequence with the history preserved at the site.

What works and what does not

Strengths

  • The quest gives all four Sage abilities a distinct puzzle-solving purpose after the main Regional Phenomena quests.
  • The four named riddles provide a clear structure for tracking progress through the ruins.
  • Solutions produce tangible rewards, including hidden chests and the Dusk Claymore.
  • The monoliths add historical context about the king and sages who opposed the Demon King.

Weaknesses

  • The quest cannot be fully accessed before the main Regional Phenomena quests are complete.
  • The supplied sources do not establish exact routes, enemy encounters, or detailed puzzle inputs for each riddle.
  • Players who do not connect each clue with the correct Sage ability may need to revisit the monolith text.

Best uses

  • Complete it as a return trip to Thyphlo Ruins after acquiring the four Sage abilities.
  • Read every monolith before beginning the individual tasks so the four-part structure is clear.
  • Use the stone slabs and revealed chests as visual confirmation that a riddle has been solved.

    Granted for completing the entire investigation.
  • Hidden-chest rewards
