How Much Is a Mythical Chest in GPO?

What a Mythical Fruit Chest costs in GPO — 3,750 Robux, or 3,500 plus five Legendary chests — and what is inside.

A Mythical Fruit Chest costs 3,750 Robux from the in-game shop, or 3,500 Robux plus five Legendary Fruit Chests in the Trading Hub — 3,000 if you own an All Seeing Eye. It guarantees one Mythical devil fruit, drawn from eight at 12.5% each.

Updated 14 September 2026.

Every way to get one

From the chest's own Fandom article, read 8 September 2026:

Route Cost
In-game shop 3,750 Robux
Trading Hub exchange 3,500 Robux + 5 Legendary Fruit Chests — or 3,000 Robux + 5 with an All Seeing Eye
Traveling Merchant Peli, level 375 required
Impel Down Raid shop 200,000 points
Juzo the Diamondback a drop, chance unstated on the wiki

The All Seeing Eye discount is 500 Robux, once per chest. That is worth reading twice if you are buying more than a couple: the ASE is a Mythical accessory in its own right, and it also quadruples Legendary and Mythical drop rates on 2x Logia Weekends for inventory-added fruits.

The Trading Hub exchange sits by Phoeyu's stall near the waterfall, which also sells custom grips for Peli or Robux.

What is inside

The chest is single-use and guarantees a Mythical fruit — 100%. Which one is a flat roll across eight:

Fruit Chance
Tori-Tori no Mi, Model: Phoenix 12.5%
Mochi-Mochi no Mi 12.5%
Ope-Ope no Mi 12.5%
Doku-Doku no Mi (Venom) 12.5%
Hito-Hito no Mi, Model: Daibutsu (Buddha) 12.5%
Ryu-Ryu no Mi, Model: Pteranodon 12.5%
Soru-Soru no Mi (Soul) 12.5%
Uo-Uo no Mi, Model: Seiryu (Dragon) 12.5%

One in eight is Dragon, which is the outcome everyone is actually buying for — and the eight outcomes of that flat roll are nothing like equal in trade. In every one of the fourteen daily solves to 8 September 2026, Dragon was worth roughly an order of magnitude more than the weakest of the other seven — never less than eight times it — with Buddha and Ope taking turns at the bottom. Trade values move hourly; the live number is on gpovalues.com/item/<slug> — Dragon, Buddha and Ope each have their own page.

Opening one for the first time grants the "Mythic Chest Opener" title.

The arithmetic nobody writes down

If Dragon is what you want, a chest is a 12.5% draw at 3,750 Robux. The expected number of chests to see one Dragon is eight, so the expected Robux cost of a Dragon through chests is around 30,000 Robux — and you keep seven other Mythicals along the way.

Whether that is good value depends entirely on whether you want the other seven. Our solve keeps six of them bunched inside a narrow band well under Dragon, so the "consolation prizes" are not worthless — but they are not Dragon either. Check the live figure on each fruit's gpovalues.com page rather than a number printed here.

The Legendary Fruit Chest route

The Trading Hub exchange asks for five Legendary Fruit Chests alongside the Robux, which makes the Legendary chest the other half of this purchase rather than a separate item.

That matters if you farm. Legendary fruits spawn at 4% on an ordinary day and 8% on a 2x Logia Weekend — Friday, Saturday and Sunday — and quadruple to 16% for inventory-added fruits if you hold an All Seeing Eye during one of those weekends. Legendary chests are therefore something a determined player accumulates; Mythical chests are not.

So there are really two prices for a Mythical chest: 3,750 Robux and no effort, or 3,000–3,500 Robux plus the farming that produced five Legendary chests. Which is cheaper depends entirely on what your time is worth.

Stacking and storage

The wiki gives two different numbers here and we are not going to pick one for you: the article body says "You're only able to carry a max of 10 of them at a time", while its own infobox lists a max stack of 5. Treat 5 as the safe assumption and check in game before buying in bulk.

Price history worth knowing

The chest has not always cost this. From the wiki's trivia:

Why it is our value anchor

The Mythical Fruit Chest is the unit our GPO value engine is anchored on: Mythical Fruit Chest = 10,000 in the solve that runs hourly over the full recorded GPO trade corpus. It is a good anchor precisely because it is a fixed-price, fixed-contents item that a large number of players buy and trade, so its value moves less than the fruits it contains.

When you read a GPO value on our site or on gpovalues.com, you are reading it in chests.

Where to buy

We list the chest itself and every one of its eight outcomes. That is the shelf, not a stock report — availability changes, so check each page rather than this list:

Buying the fruit directly removes the roll. Buying the chest keeps it.
