Fortnite: How to Open the Secret Duck Vault in Cluster Coast

• The Cluster Coast secret vault requires no key, keycard, or Gold to open — just a rubber duck wearing sunglasses.
• The duck (Suspicious Duck) spawns randomly in one of four locations around the central mansion every match.
• Find the duck, interact to collect the Duck Key, carry it to the smaller building opposite the mansion, and place it in the display case.
• Placing the duck in the display case lowers the entire floor like an elevator — it does not open a door. Stand on the floor when it descends.
• Inside the vault: over 2,000 Gold, 2 Rare Chests, 2 standard Chests, and 2 Ammo Crates — the highest consistent Gold yield of any secret room in Season 3.
• The vault contains a port-a-potty escape route so you can exit without backtracking through the main building entrance.
• The puzzle resets every match — you can run this vault in every game you land at Cluster Coast.

The Fortnite Cluster Coast secret duck vault is the best free loot room in Chapter 7 Season 3. No key, no keycard, no Gold required — just a rubber duck and 30 seconds of puzzle solving. The reward is over 2,000 Gold and two Rare Chests in the opening minute of a match, making it one of the strongest early-game advantages available on the Shattered Coast map. This guide covers every duck spawn location, the exact route to the vault, and the mechanics most players miss on their first attempt.

What Is the Cluster Coast Secret Duck Vault

The Cluster Coast duck vault is a hidden basement loot room beneath a building at the Cluster Coast POI on the southeastern edge of the Shattered Coast map. It is completely separate from the standard vault system — it does not require a Rare Vault Key or an Epic Vault Keycard. Instead, it uses an environmental puzzle built around a single prop: a rubber duck wearing sunglasses.

The vault is one of five confirmed secret loot rooms in Chapter 7 Season 3. Of all of them, it offers the most consistent Gold payout — over 2,000 Gold every match, outperforming both the Secret Aquarium near Heatwave Harbor (around 1,500 Gold) and the best-case outcome of the Gambling Garage at The Battlewoods (also around 2,000 Gold, but randomised).

The puzzle resets every match. This is not a one-time unlock — you can run this vault every single game you land at Cluster Coast.

Where Is Cluster Coast on the Fortnite Map

Cluster Coast is in the southeastern area of the Shattered Coast map. It is described by Epic as the lavish headquarters of Cluster the Duck — a duck-themed NPC with his own duck-shaped yacht moored nearby. The POI features a central mansion, outdoor pools, a canal, and the distinctive duck yacht where the Cluster NPC can be found.

The mansion is your primary landmark for the entire puzzle. When you arrive at Cluster Coast, orient yourself by finding the central mansion directly across from the duck-shaped yacht. The Cluster NPC on the yacht confirms you are in the right area. Everything in the duck vault puzzle revolves around the mansion and the smaller building directly opposite it.

All Suspicious Duck Spawn Locations

The Suspicious Duck — a rubber duck wearing sunglasses — is the key to the vault. It spawns randomly in one of four locations around the central mansion each match. It is never in the same spot two matches in a row. You need to check all four locations until you find it.

The four spawn points, in the recommended search order:

1. Golden Fountain (Most Common)

The golden water fountain sits in the front courtyard of the mansion, directly in the centre of the Cluster Coast POI. This is the most reported spawn location. Check here first — if the duck is here, you can grab it and start the puzzle before any enemies who also know about the vault.

2. Indoor Pool — Left Room of the Mansion

Enter the mansion and check the swimming pool in the room on the left side of the interior. This is the second most common spawn. The pool is clearly visible when you enter the left wing of the mansion.

3. Aquarium — Right Wing of the Mansion

The mansion contains an aquarium in its right wing. The duck can spawn inside or near the aquarium tank. Check here if you have not found it at the fountain or left pool.

4. Outdoor Terrace Pool

If the duck is not at any of the first three locations, check the small outdoor decorative pool on the exterior terrace of the mansion. This is the least common spawn but is always the fallback if the other three are empty.

The duck is easy to identify — it is a rubber duck with visibly styled sunglasses on it, sitting in or near water. Approach it and press the interact button to collect it as the Duck Key. It goes straight into your inventory.

How to Open the Secret Duck Vault: Step by Step

Step 1: Find the Suspicious Duck and Collect the Duck Key

Sweep the four mansion spawn locations in order — golden fountain first, then left pool, then aquarium, then outdoor terrace. Interact with the duck the moment you find it. The Duck Key appears in your inventory.

Step 2: Go to the Smaller Building Opposite the Mansion

With the Duck Key in hand, leave the mansion and find the smaller building directly opposite it. This building is not inside the mansion — it is a separate structure across from the main entrance. Head to its main door and enter.

Step 3: Find the Cluster Poster and the Door

Once inside the smaller building, look for the giant Cluster poster mounted on the wall. This poster — featuring Cluster the Duck branding — is your navigation landmark inside the building. Immediately to the left of the poster is a door. Go through it.

Step 4: Locate the Glass Display Case

Through the door, you will find a large glass display case in the first room on the left. It will be empty — it is waiting for the Duck Key.

Step 5: Place the Duck Key in the Display Case

Interact with the display case and select the option to place the Suspicious Duck inside it. The moment you do this, a hidden mechanism activates and the entire floor begins to lower like an elevator.

This surprises most players on their first attempt. There is no door that swings open. The floor itself descends — stand on it while it drops. It takes a few seconds to fully lower. Once the platform stops, you are standing in the secret basement directly in front of the vault.

Step 6: Enter the Vault and Collect Everything

The vault door unlocks automatically when the floor stops descending. Walk left through the basement and enter the now-open hermetic vault door. Collect all loot inside.

Step 7: Use the Port-a-Potty to Exit

Inside the vault, you will find a port-a-potty in the corner. This is your escape route. Use it to teleport out of the basement without backtracking up through the building’s main entrance — which may now have enemies watching it if anyone saw you enter.

The port-a-potty exit is not just a cosmetic Easter egg. It is the safest way out. After collecting 2,000+ Gold and multiple chest items, you are a high-value target. Using the alternate exit removes the predictability of your departure point.

All Loot Inside the Cluster Coast Duck Vault

The vault contains a consistent loot package every match:

• Over 2,000 Gold Bars — the highest guaranteed Gold yield of any secret room in Chapter 7 Season 3
• 2 Rare Chests — high-rarity weapon drops, with a confirmed chance of a Legendary Hunting Rifle
• 2 standard Chests — additional weapons and consumables
• 2 Ammo Crates — ammunition to match your new loadout

The Rare Chests are the headline items for weapon quality. The Gold haul is what makes this vault the best early-game loot location accessible without RNG gating. Over 2,000 Gold in the first minute of a match lets you hire an NPC Specialist, use vending machines, open the Gambling Garage at The Battlewoods, and still have Gold left for mid-game needs.

Why the Cluster Coast Vault Is Better Than Other Secret Rooms

There are three main accessible secret loot rooms in Chapter 7 Season 3. Here is how they compare:

• Cluster Coast Duck Vault — Free to enter, 2,000+ Gold every match, 2 Rare Chests, consistent returns. Requires solving the duck puzzle but no RNG gating beyond finding the duck spawn. Port-a-potty escape. Best overall value.
• Secret Aquarium, Heatwave Harbor — Free to enter, around 1,500 Gold, weapons, Rare Chest in the penthouse. Requires navigating to a separate island south of the harbor. Instant-kill trap if you stand under the aquarium when it breaks. Good Gold yield but lower than the duck vault.
• Gambling Garage, The Battlewoods — Costs 500 Gold to open. Random outcome — best case is around 2,000 Gold and chests, worst case is toilet rolls and ammo. No skill expression, pure RNG. Worth attempting if you are already in Battlewoods with spare Gold, but not worth a detour.

The Cluster Coast vault wins on consistency. Every match delivers the same 2,000+ Gold and 2 Rare Chests. The only variable is which of the four duck spots holds the Suspicious Duck that match — and checking all four takes under a minute.

Tips for Running the Duck Vault Efficiently

• Check the golden fountain first every match. It is the most common spawn. If the duck is there, you save the time of sweeping all four spots.
• Do not clear the mansion before getting the duck. Go straight to the fountain the moment you land. Every second spent looting rooms before getting the Duck Key is time another player who knows the vault can get there ahead of you.
• In squads, split roles. One player grabs the duck while teammates cover the exterior of the smaller building and watch for enemies approaching the vault entrance.
• Use the port-a-potty every time. Do not leave through the main building entrance after collecting vault loot. Other players know the vault exists and may be waiting at the entrance after hearing you go in.
• Pair this vault with the Sprite Chest at Cluster Coast. There is one Sprite Chest spawn at Cluster Coast as well. After exiting via the port-a-potty, sweep the area for the Sprite Chest spawn before rotating. You can potentially collect a Sprite and 2,000 Gold in the same drop.
• This is a viable drop in every match. Cluster Coast is less contested than Sinister Strip or Heatwave Harbor. The vault puzzle filters out players who do not know about it. If you know the route, you have a significant advantage over everyone else landing in the same area.
