One of Zelda: Tears of the Kingdom's many side quests takes Link back to Zora's Domain to help out everybody's favorite shark-man Sidon. Completing 'Secret Treasure Under the Great Fish' will not only net Link some cool new armor, but also enhance Sidon's Sage Ability - something that could prove vital to gameplay. Read on to discover how to complete this side quest in Tears of the Kingdom, and receive the Vah Ruta Divine Helm in return.
How to Trigger the Secret Treasure Under the Great Fish Side Quest
In order to trigger the 'Secret Treasure Under the Great Fish' Side Quest, players must first complete the Zora section of main quest 'Regional Phenomenon' - 'Sidon of the Zora'. Once peace has been restored to Zora's Domain, players will find Sidon waiting at the topmost platform of Zora's Domain, next to King Dorephan.
Players will know that the side quest can be triggered by the red exclamation mark next to Sidon's thought bubble. Talk to him, and he will tell Link of a riddle that spoke of a secret treasure - "Below the long bridge that reaches for the statue, leave your fears behind. Pass beneath two waterfalls to reach your prize".
How to Complete the Secret Treasure Under the Great Fish Side Quest
With Sidon's cryptic riddle in mind, head down the long bridge that leads out of Zora's Domain.
How to Find the Two Waterfalls
On the long bridge, dive into the water where the line on the map indicates a large waterfall. Using Zora Armor will help with Swim Speed here, but Link doesn't want to swim up the waterfall - he wants to swim through it. Dash using the 'A' button when close to the waterfall to reach 'The Cave Under Zora's Domain'.
Directly ahead at this point is another waterfall. This is the second waterfall spoken of in the riddle.
The Treasure in the Cave
Through the second waterfall, there should be a Treasure Chest containing the secret treasure - the Vah Ruta Divine Helm. Opening this Treasure Chest completes the quest, though speaking to Sidon after completing it will offer some additional unique dialogue.
What Does the Vah Ruta Divine Helm Do?
The Vah Ruta Divine Helm is a reference to the Divine Beast Vah Ruta in Breath of the Wild. Wearing it will increase Swim Speed by one level, but that's not all. When Link is wearing the Divine Helm, the Sidon Sage Spirit will wear it too, and the water shield/weapon ability will be boosted.
The Legend of Zelda: Tears of the Kingdom is available for the Nintendo Switch.
