Chests are scattered across the islands of Haze Seas and are one of the easiest ways to earn passive cash and Gems as you explore. Most chests are safe to open, but a rare few are Mimics — monster chests that fight back and drop an exclusive reward. This guide covers every chest tier, its drop rates and rewards, how the Mimic chest works, and the titles you can earn from opening them.
Chest Tiers & Drop Rates
Every chest rolls a rarity when you open it, and the cash reward scales with where you are: rewards are 1.5x in Sea 2 and 2x in Sea 3 compared to Sea 1. Here’s the full breakdown:
| Chest Tier | Chance | Reward |
|---|---|---|
| Common | 60% | 100 – 1,000 Beli |
| Uncommon | 25% | 1,000 – 3,000 Beli |
| Rare | 10% | 3,000 – 5,000 Beli |
| Legendary | 4% | 5,000 – 10,000 Beli |
| Mythical | 0.99% | 15,000 Beli + 5 Gems |
| Mimic | 0.01% | 50,000 Beli + Little Lamb boat (exclusive) |
The Little Lamb boat from a Mimic is one of the rarest cosmetics in the game. If you’re after boats through normal means instead, our Ships & Gamepasses guide covers every purchasable vessel.
The Mimic Chest (Chest Monster)
A Mimic spawns in place of a normal chest and looks identical to a real one — until you open it and it attacks. Defeating a Mimic rewards you with the exclusive Little Lamb boat, making them worth hunting despite the risk.
| Mimic Stat | Value |
|---|---|
| HP | Takes 100 attacks/ticks of any kind to defeat |
| Attack | Deals 10% of your HP per hit |
Because a Mimic chips away 10% of your health per attack, come prepared with a strong build. Our Devil Fruits guide and Swords guide can help you pick high-damage options to burn one down quickly.
Chest Titles
Opening chests progresses several collection titles, including a couple tied specifically to the rare chest types:
| Title | How to Unlock |
|---|---|
| Vaultbreaker | Open 25 chests |
| Treasure Hunter | Open 250 chests |
| Chosen of Fate | Open a Mythical chest |
| Lured by Loot | Open a Mimic / fake chest |
For the full title checklist across the whole game, see our Titles guide.
Chest Farming Tips
Since cash rewards multiply in later seas, opening chests is far more profitable once you’ve progressed — a Mythical chest in Sea 3 is worth double what it is in Sea 1. Grab chests opportunistically while sailing between islands or waiting on boss timers, and don’t panic if one turns out to be a Mimic: if your build can survive 100 ticks of damage, the Little Lamb boat is a guaranteed payoff. Use our Islands & Map guide to plan efficient routes past chest-heavy locations.
Frequently Asked Questions
What is the rarest chest in Haze Seas?
The Mimic chest is the rarest at just a 0.01% spawn chance. Defeating one rewards 50,000 Beli plus the exclusive Little Lamb boat.
How do chest rewards scale between seas?
Cash rewards are 1.5x in Sea 2 and 2x in Sea 3 compared to Sea 1, so the same chest tier pays out more the further you progress.
How do you beat a Mimic chest?
A Mimic takes 100 attacks or ticks of any kind to defeat and deals 10% of your HP per hit, so bring a durable, high-damage build to outlast and beat it.
