Quick answer: find Zola Zar in the Northern Slope Cavern on Layali Grove (Operations), complete every task he hands you — helmet, armour, weapon accessories, supplies, chest rig, an underwater backpack — then clear his final combat mission, extract, and claim the gold Vigil Harmonica from Zola's Thank-You Letter in your lobby mail.
What the Vigil Harmonica is
The harmonica is a gold-tier collectible described in-game as an old instrument marked by time and war. It is not a loot drop and cannot be bought. Once claimed it lives in your Collection Room and can be slotted into an EDC Tool Kit display. Inspecting it opens a note overlay — play the sequence and it performs the Song of Al-Saraf. And it is not the only tune the instrument knows: two scores come built in, and four more are hidden, each unlocked by playing a note pattern to an NPC in the field.
The four hidden scores (PC and mobile inputs differ)
The hidden scores are Nightingale, Watch, Rising Wind and Daybreak (the names the Chinese community uses; the global client's labels may differ). Each one is triggered by a different quest NPC: Zola in the waterfall cavern, Joe Reed, and Taj. The mechanic is the same every time — and it is where most players fail:
- Let the NPC hum first. Wait until they finish their tune and your character pulls the harmonica out by themselves. Drawing the harmonica manually will not trigger anything.
- The inputs are not shared between platforms. PC players tap letter keys and hold mouse buttons; mobile players tap on-screen number buttons. The sequences below are per platform.
- Daybreak needs the other three first. Collect Nightingale, Watch and Rising Wind, re-roll into a fresh match, then go back to Zola.
| Score | Trigger NPC | PC input | Mobile input |
|---|---|---|---|
| Nightingale | Zola, in the waterfall cavern | Tap M–N–M, hold N, then hold the middle mouse button and tap C–B–V; press Q to submit | Tap 7–6–7–6, long-press 6, then tap 3–5–4 and submit |
| Watch | Joe Reed, the angler | Hold the left mouse button and tap B–Z–X–C–B–V–C–Z–X–C, then submit | Tap 5–1–2–3–5–4–3–1–2–3 and submit |
| Rising Wind | Taj, on patrol | Hold left button and tap N–M, release, tap Z–X–Z, then hold left button and tap M–Z, submit | Tap 6–7–1–2–1–7–1 and submit — natural notes only, no pitch shifts needed (verified in our own game) |
| Daybreak | Zola again, after the other three — in a fresh match | Tap M–N–C–N–M–N–M, then right-click and tap Z–V–C–V | Tap 7–6–3–6–7–6–7, then raised 1–4–3–4 and submit |
Hidden-score triggers and note inputs: a Chinese community guide dated September 15, 2026 (18183), read October 11, 2026 and re-worded; the mobile input for Rising Wind is our own correction from in-game testing — natural notes only, no pitch shifts. The score names above are the community's translations; the global client's labels may differ. Timing is the common failure point — the NPC must finish humming before the input window opens.
Requirements
- Mode and map: Operations, Layali Grove.
- Safe box discipline: every quest item goes into the safe box the moment you pick it up — the single most common way to lose a day's progress.
- Diving gear: a Level 2 or 3 Diving Center and Tempest equipped, for the underwater task.
- Money: nothing — Zola pays you for the supply-buying task.
- Order matters: items grabbed before their objective is accepted do not count. Accept the task first, then go fetch.
All Zola tasks, in order
- Meet Zola Zar. Deploy into Layali Grove and route to the Northern Slope Cavern. Talk to Zola and accept the first task.
- The helmet. Clear the manor guards, kill Reis, and take the Lost Hero's Helmet from beside his loot crate — it spawns next to the crate, not inside it. Safe-box it, extract or hand it in.
- The armour. Swim the flooded passage on the left side of the cave system, kill the crocodiles in the deep chamber, and take the soldier's armour off the central rock.
- Weapon accessories (after a daily reset). Seven accessories across four spots: two on the ground at the minefield outside the waterfall exit; one on the Aminya Village rooftop (use the ladders); one on the hull of the tank north-east of the Sparkling Empress Hotel; three in the floor container of the small house on the far left of the Gharbi Building.
- Supplies. Zola pays you. Buy purified water, medical alcohol, canned rations and basic fuel, load them before deploying, and place one set at each of the two marked house doors in Aminya Village.
- The chest rig. Back to Aminya Village, under the church structure. Pick it up, safe-box it, return it.
- The underwater backpack (after another reset). Deploy with the Diving Center and Tempest, dive the submerged trench off the southern water, follow the cave turns to the quest backpack, and surface. A teammate makes this leg much safer.
- The final mission. Equip the full recovered set from the stand in Zola's cave — wearing it is part of the task. Clear the Haavk soldiers at Transnova Station and the Radar Station lab, shoot down the helicopter that arrives, loot the final items, and extract successfully.
- Claim it. Back in the lobby, open the mail: Zola's Thank-You Letter holds the Vigil Harmonica. One click and it is in your Collection Room.
The quest's five recovery objectives, as they appear in game:
Why the chain stalls
- A quest item was lost on death because it never entered the safe box.
- Items were collected before the task was accepted — the game credits nothing fetched early.
- The next task has not refreshed — check the reset time shown in the task prompt.
- The dive was attempted without the Diving Center and Tempest.
- Only some of the seven accessories were collected; all four locations must be cleared.
- The final mission ran but ended without an extraction, so the items never made it back.
