The Gem Duck Sprite is one of the rarest Sprite variants in Fortnite right now, added on August 6 as part of the ongoing Chapter 7 Season 3 Sprite collection. Unlike most Sprites that rely on random spawns or drop rates, this one has a fixed, guaranteed source — but getting to it takes a few steps and some competition from other players who've read the same teaser.
Where is the Mogul Vault in Fortnite?
The Mogul Vault sits inside the Secret Duck Vault at the Cluster Coast POI. The in-game teaser describes it as "the vault of a certain business mogul," which is a nudge toward Cluster Coast without spelling it out directly. Once you know where you're going, the route is straightforward — but you need the right item before you can open the door.

How to find the Suspicious Duck at Cluster Coast
Before you can enter the vault, you need the Rubber Duck Keycard, and that comes from interacting with the Suspicious Duck. This duck doesn't sit in one fixed spot — it can spawn in four different locations across Cluster Coast:
- The outdoor swimming pool on the western side of the POI
- The indoor swimming pool in the building adjacent to the outdoor pool
- The aquarium inside the same building as the indoor pool
- The golden duck fountain in the center of Cluster Coast
Check all four spots if you don't find it immediately. Once you locate the Suspicious Duck, interact with it and it hands over the Rubber Duck Keycard.

How to open the Secret Duck Vault
With the Rubber Duck Keycard in hand, look for the house inside Cluster Coast that has a poster reading "Get Flocked" on it. That's your landmark. Inside, find the empty display case and place the keycard into it. The entrance to the Secret Duck Vault opens up, and the Gem Duck Sprite is waiting inside.
This is the only confirmed method to obtain the Gem Duck Sprite, and the upside is that it's a guaranteed drop rather than a low-percentage random spawn. The downside is that every other player who knows about this vault is heading to the same POI, so expect a fight.
How does the Gem Duck Sprite compare to other Sprite types?
The Gem Duck sits within the broader Gem Sprites category, which carries a 30% fall damage reduction buff — making it one of the more practically useful Sprite types to have equipped during a match. For a full breakdown of every Gem Sprite variant, spawn locations, and drop rates, the Fortnite Gem Sprites guide covers all nine variants in detail.
| Sprite Type | How to Obtain | Key Benefit |
|---|---|---|
| Gem Duck Sprite | Mogul Vault at Cluster Coast | 30% fall damage reduction |
| Duck Sprite | Random world spawns | Shield regeneration |
| Quack Sprite | Sprite Mastery level unlocks | XP sharing |
| Gold Sprite | Random rare spawns | XP bonus |
| Fishy Sprite | Fishing locations | Swimming speed boost |
| Gummy Sprite | World spawns | Sprite Dust farming |
What other Sprites should you collect alongside the Gem Duck?
The Sprite system in Chapter 7 Season 3 rewards players who collect across multiple types. If you're building out your collection, the Duck Sprite guide walks through the standard Duck Sprite variants and their shield regen ability, while the Quack Sprites guide details the XP-sharing mechanic and the exact Sprite Mastery levels needed to unlock each variant.
For players focused on rare finds, the Gold Sprite guide is worth reading since Gold Sprites carry XP bonuses and have some of the lowest spawn odds in the game.
