Flute of the Tides is a Mystic Skill in Where Winds Meet that unlocks through an Exploration quest in the Hexi region. The quest is easy to miss because it does not begin from a normal dialogue prompt the moment you arrive.
Quick answer: Go to Peaceward Camp in Jade Gate Pass, find Monk Unknowing on the raised wooden platform, play Kalavinka on the flute to trigger the quest, then complete the two flute performances at Whitecrown Fortress and Heroic Tomb before returning to him.

Flute of the Tides trigger condition
The exact trigger is playing the flute for Monk Unknowing in Peaceward Camp. Simply reaching the area is not enough, and the quest ping does not appear until the performance is completed.
| Requirement | Exact condition |
|---|---|
| Region | Jade Gate Pass, Hexi |
| NPC | Monk Unknowing |
| Starting point | Peaceward Camp, slightly northeast of Jade Gate Pass |
| Unlock requirement | Talk to the Wayfarer of Jade Gate Pass |
| Quest trigger | Play Kalavinka on the flute for Monk Unknowing |
Where Monk Unknowing is
Monk Unknowing is in Peaceward Camp, just ahead of the Peaceward Camp Boundary Stone. He stands on a raised wooden platform and is already playing the flute when you approach.
If you are looking for the fastest way to verify you are in the right place, check for the platform first. That visual landmark is more reliable than wandering through the camp waiting for a quest marker that has not appeared yet.

How the Flute of the Tides quest works
Step 1: Reach Peaceward Camp in Jade Gate Pass after meeting the unlock requirement tied to the Wayfarer of Jade Gate Pass. Approach Monk Unknowing and interact with him.
Step 2: Play his song, Kalavinka, on the flute. In the rhythm mini-game, match the falling notes to the scanline in time with the beat.

Step 3: Speak to Monk Unknowing again after the song ends. He then asks you to perform at two memorial locations tied to fallen Anxi soldiers.
Step 4: Travel to Whitecrown Fortress, southeast of Peaceward Camp. Follow the quest marker to the small white beam on the ground and play the shorter flute passage there.

Step 5: Go to Heroic Tomb in the Ayisu sub-region, near the lake leading toward the tombs. Perform the flute piece again at the marked spot.
Step 6: Return to Monk Unknowing in Peaceward Camp and talk to him to complete the quest. That final hand-in gives you Flute of the Tides.

How to know the unlock worked
You will know the trigger worked when the quest ping appears after the opening performance for Monk Unknowing. You will know the full unlock is complete when the return trip to Peaceward Camp ends with the quest reward, and Flute of the Tides is added as your Mystic Skill.
Why Flute of the Tides may not trigger
The most common failure point is trying to talk to Monk Unknowing without first playing his music. The quest also will not start before the Jade Gate Pass unlock requirement tied to the Wayfarer is cleared.
If you are already at Peaceward Camp and nothing happens, the missing action is usually the flute performance itself, not a combat or exploration step.
What Flute of the Tides does
Flute of the Tides rewards you with a Mystic Skill of the same name. Its effect is a broad burst of damage followed by a summoned flute attack that keeps striking nearby enemies.
It is treated as a high-impact area skill, making the unlock valuable even if your only goal is to collect core Mystic Skills in Hexi.

For anyone trying to unlock it fast, the key detail is simple: the quest starts with a performance, not a normal pickup. Once Monk Unknowing acknowledges Kalavinka, the rest of the route is just Whitecrown Fortress, Heroic Tomb, and a final return to Peaceward Camp.
