Misko's Treasure: The Fierce Deity guide

Misko's Treasure: The Fierce Deity is a side quest about locating the three pieces of the Fierce Deity armor set and using the completed outfit to reveal a hidden reward.

The quest begins in Cephla Lake Cave after Link has completed Misko's Cave of Chests. A letter in a bottle inside the cave provides the clue that starts this treasure hunt, shifting the focus from the cave's earlier chest puzzle to a set of riddles connected with the Fierce Deity armor.

The three armor pieces are placed in separate caves: Ancient Tree Stump Cave, Skull Lake Cave, and Akkala Citadel Ruins Summit Cave. The quest is therefore a travel-and-exploration objective rather than a single combat encounter. Each destination contains a cave chest holding one part of the set, and the armor must be recovered from those specific chests for the quest to register correctly.

Once all three pieces have been found, equip the complete Fierce Deity set and return to the relevant secret door in Cephla Lake Cave. Opening it completes the treasure hunt and grants the Fierce Deity Sword. The armor also carries the Attack Up effect, making the set useful beyond the quest itself.

Amiibo scans can provide Fierce Deity armor pieces, but those scanned items do not fulfill the quest's completion requirements. To finish this quest properly, collect the armor from the chests in Ancient Tree Stump Cave, Skull Lake Cave, and Akkala Citadel Ruins Summit Cave before attempting to open the hidden door.

WalkthroughSpoilers

  1. 01

    Complete the prerequisite quest

    Complete Misko's Cave of Chests

    Finish Misko's Cave of Chests before attempting to start this treasure quest. Without that prerequisite, the letter-based sequence for Misko's Treasure: The Fierce Deity is not ready to begin.

    Location: Misko's Cave of Chests

    TipTreat this as a preparation step rather than searching the three armor caves immediately.

  2. 02

    Find the letter in a bottle

    Search Cephla Lake Cave for the bottle

    Enter Cephla Lake Cave and look for the letter in a bottle. Reading or investigating this clue is the trigger that establishes the Fierce Deity armor search.

    Location: Cephla Lake Cave

    Watch outFinding armor through another method does not replace this quest-start step.

  3. 03

    Recover one Fierce Deity armor piece

    Follow the first riddle to Ancient Tree Stump Cave

    Use the riddle sequence to identify Ancient Tree Stump Cave as one of the destinations. Search inside the cave for its quest chest and take the Fierce Deity armor piece rather than relying on an Amiibo version.

    Location: Ancient Tree Stump Cave

    TipRecord which of the three named caves you have cleared so the same clue is not revisited unnecessarily.

  4. 04

    Recover one Fierce Deity armor piece

    Follow the second riddle to Skull Lake Cave

    Continue with the clues until they point to Skull Lake Cave. The required armor piece is hidden in a cave chest there, and collecting it from that chest is important for quest completion.

    Location: Skull Lake Cave

    Watch outA scanned copy of the matching armor does not satisfy the quest requirement.

  5. 05

    Recover the final Fierce Deity armor piece

    Follow the third riddle to Akkala Citadel Ruins Summit Cave

    Use the remaining riddle to locate Akkala Citadel Ruins Summit Cave. Search its chest for the final required armor piece, completing the set collected through the quest locations.

    Location: Akkala Citadel Ruins Summit Cave

    TipCheck that all three quest caves have supplied a piece before returning to Cephla Lake Cave.

  6. 06

    Prepare the set for the final door

    Equip the complete Fierce Deity set

    Put on all three Fierce Deity armor pieces at the same time before interacting with the final door. The door checks for the completed equipped set, not merely for ownership of unrelated scanned pieces.

    Location: Cephla Lake Cave

    Watch outDo not expect the secret door to open while the full set is not equipped.

  7. 07

    Claim the final reward

    Open the secret door and claim the sword

    Return to the hidden door in Cephla Lake Cave while wearing the complete Fierce Deity set. Opening it concludes the treasure sequence and grants the Fierce Deity Sword.

    Location: Cephla Lake Cave

Mission mechanics

This quest uses a clue-and-location structure. The letter in a bottle begins the sequence, and the riddles point to three separate cave destinations rather than placing all of the required treasure in Cephla Lake Cave.

Quest completion depends on provenance as well as possession. The relevant Fierce Deity pieces must be taken from the specified cave chests; obtaining equivalent pieces from Amiibo scans does not satisfy the quest's progression check.

The final interaction is equipment-based. Once the three quest pieces have been collected, wearing the full Fierce Deity set enables the secret door in Cephla Lake Cave to open. The reward beyond that door is the Fierce Deity Sword, while the armor supplies an Attack Up effect.

What works and what does not

Strengths

  • The quest gives the player a clear treasure-hunt structure built around riddles and named cave destinations.
  • The Fierce Deity armor has an Attack Up effect, giving the search a practical combat benefit.
  • The final reward adds the Fierce Deity Sword to the armor-focused objective.

Weaknesses

  • The quest requires travel between three separate caves before the finale can be attempted.
  • Amiibo versions of the armor do not count, so players who already own those pieces still need to search the quest chests.
  • The source material does not describe the riddles in full, so this page cannot reproduce their exact wording or provide clue-by-clue interpretations.

Best uses

  • Use the quest as an exploration route for collecting a complete Fierce Deity equipment set.
  • Equip the set after the three chest-based objectives are complete to access the hidden-door reward.

AftermathSpoilers

The treasure behind the door

With the complete Fierce Deity set equipped, the secret door in Cephla Lake Cave opens and rewards the Fierce Deity Sword. The armor remains useful afterward because its Attack Up effect supports combat outside this quest.

Trivia

  • The quest is unusual in that possession of equivalent Amiibo-granted armor is not enough to complete its progression checks.
  • Its required treasure is distributed across Ancient Tree Stump Cave, Skull Lake Cave, and Akkala Citadel Ruins Summit Cave.
  • The quest combines a three-piece armor search with a final equipment-gated door interaction.
