Rare pulls in Rock Fruit come from the game’s random drop systems, not from a fixed shop purchase. To land a rare item like Jimina, you feed Diamonds into the Random Chance chest and stack Lucky Drop boosts so each roll has a better shot at the top-tier pools. Everything below focuses on the exact mechanic that produces those drops and how to fund it quickly.
Quick answer: Open the Random Chance chest inside the spawn building, spend Diamonds on rolls (50 Diamond for x1 or 250 Diamond for x5), and activate a Lucky Drop/Lucky Potion boost from codes before rolling to raise your odds on the Devil Fruit, Event, and Secret pools.
Where rare drops come from in Rock Fruit
The Random Chance chest sits on the bar counter inside the main spawn building (the SafeZone). Interacting with it opens a roll panel that draws from four separate pools, each with its own chance. Rare content lives in the lower-percentage pools, so most of your value comes from the Devil Fruit, Event, and Secret tiers rather than the common item pool.
| Pool | Chance |
|---|---|
| Random Item | 78% |
| Random DevilFruit | 14% |
| Random Item Event | 7% |
| Item Secret | ??? |
Rolls cost Diamonds. A single pull is 50 Diamond, and a five-pull batch is 250 Diamond. Because the rare pools are a small slice of every roll, the fastest route to a specific rare is high roll volume combined with an active luck boost, not a handful of single spins.
Stack Diamonds and Lucky Drop boosts before rolling
Two things decide how quickly you hit a rare pull: how many Diamonds you can spend, and whether a Lucky Drop boost is running while you spend them. Codes are the quickest way to get both at once, since several current codes hand out Diamonds and Lucky Potions together. Activate the luck boost first, then burn your Diamonds during that window.
Tip: Redeem code-based Lucky Potions right before a batch of 250 Diamond (x5) rolls so the boost covers as many pulls as possible instead of expiring between spins.
You also earn Diamonds through Diamond Quests in the Menu, and Beli from defeating enemies, which keeps your economy moving between code redemptions. Diamonds are the resource that matters for the chest, so prioritize anything that pays out Diamonds and luck boosts.
Active Rock Fruit codes for Diamonds and Lucky Potions
These codes are working right now and are the cheapest way to build up rolls. Codes are case-sensitive, so enter them exactly as shown.
| Code | Reward |
|---|---|
| MiniUpdate | Diamonds and Potions |
| Mambo | 2,500 Diamonds and x10 Lucky Potions |
| Duck | Potions |
| UPD1 | 5x Lucky Potion (x2), 5x EXP Potion (x2), 5x Diamond Potion (x2) |
| Release | 1,500 Diamonds and x2 Diamond Potions x10 |
| ReUniverse | x2 Lucky Potions x10 |
| SorryForDelay | x2 Lucky Potion x1, x2 Exp Potion x1, 2x Diamond Potion x1 |
| FixBug1 | x2 Diamond Potion x10 and x2 Exp Rebirth x10 |
| RockFruit2026 | x2 Exp Potion x10 and 5M Beli |
The Lucky Potions from Mambo, ReUniverse, and UPD1 are the ones to save for chest sessions. The Diamond rewards from Mambo and Release give you enough for several five-pull batches on their own.
How to redeem Rock Fruit codes
If a code fails, it is almost always a typo or an expired code. Copy the code exactly to avoid capitalization mistakes, and if it still refuses, the code has likely rotated out and you will need a newer one.
How to know a pull worked
When a roll lands, the reward appears immediately and is added to your Inventory, which you can open from the Menu. A rare pull will show up there instead of in the common item slots, and equippable rewards can be placed into your hotbar next to your Katana, Combat, and other gear. If the item does not appear after a roll, reopen the Inventory to refresh it before spending more Diamonds.
Fresh codes and rare drops rotate in with each update, so keep an eye on the game’s official community channels for new code drops, then funnel every Diamond and Lucky Potion into the Random Chance chest until the pull you want finally shows up.
