If you are trying to get better Cursed Fruits in Grand Blue, you will want to start paying attention to Celestial Coins. This special currency can be earned by playing the game and is mainly useful for getting rewards such as Fruit Chests.
In this post, I will show you how to get Celestial Coins, where you can farm them, and what you should spend them on. I will also explain the different ways I use to collect them while progressing through the game, so you do not have to stop everything just to farm currency.
The nice thing is that you are not limited to one method. You can earn Celestial Coins from achievements, special quests, World Bosses, and other activities while you are already exploring the world. So, let’s take a closer look at how the system works.

How to Get and Use Celestial Coins in Grand Blue
Celestial Coins are a special currency in Grand Blue that you can earn through gameplay and use for certain purchases.
One of the most useful things you can buy with them is a Fruit Chest. These chests give you Cursed Fruits, which can be used to improve your character and give you different abilities.
What I like about Celestial Coins is that you do not have to rely entirely on premium purchases to get them. You can actually earn the currency by playing the game, completing activities, and taking part in different events.
If you are trying to build a good Fruit collection, I recommend starting to save your Celestial Coins early rather than ignoring them.
How to Get Celestial Coins
There are several ways to earn Celestial Coins in Grand Blue. The main methods currently include:
• Completing Logbook achievements
• Completing quests with purple exclamation marks
• Defeating World Bosses
• Participating in certain world events and activities
You do not necessarily need to spend hours doing one specific activity. Instead, I recommend combining these methods with your normal progression.

For example, whenever I finish a few quests, I would check the Logbook to see if I have completed any achievements. When I reach a new island, I would also look around for NPCs offering special quests.
Doing this regularly lets your Celestial Coin balance build up naturally.
Get Celestial Coins From Achievements
One of the easiest methods, especially for new players, is using the Achievements section in your Logbook.
Different achievements can reward you with Celestial Coins. The nice part is that many of these objectives can be completed naturally while you are playing.
You might unlock achievements by leveling up, exploring islands, defeating enemies, or completing different activities. Because of this, you may already have Celestial Coins waiting for you without realizing it.

I recommend checking your Logbook every now and then. If you have been playing for a while and never checked your achievements, there is a good chance you have some rewards ready to claim.
Complete Purple Exclamation Quests
Another good way to earn Celestial Coins is by completing quests marked with a purple exclamation point.
These are special NPC quests that are different from the normal objectives you follow during your main progression. Some of them can reward you with Celestial Coins.
Whenever you arrive on a new island, take a little time to look around for NPCs with the purple marker. You do not have to completely abandon your main quest just to do these missions.
In fact, I recommend completing them whenever they are close to your current route. You can earn Celestial Coins while also gaining EXP and Money, which makes the time spent on these quests more useful.

Defeat World Bosses
World Bosses are another important source of Celestial Coins.
These are powerful enemies that appear as special world events. Defeating them can reward you with Celestial Coins and Fruit Chests, making them especially useful if you are trying to improve your Fruit collection.
Current information lists World Bosses as hourly events, so keep an eye out for them while you are playing.
If you see a World Boss event happening and your character is strong enough to participate, I recommend joining the fight. Even if you are mainly interested in the Fruit Chest, the Celestial Coins you earn can help you work toward another one later.
How to Use Celestial Coins
The main reason you will want to save Celestial Coins is to purchase Fruit Chests.
Fruit Chests can give you Cursed Fruits, which are an important part of combat in Grand Blue. The currently listed options are:
• 1x Fruit Chest — 1,200 Celestial Coins
• 3x Fruit Chest — 3,300 Celestial Coins
• 10x Fruit Chest — 11,000 Celestial Coins
• 20x Fruit Chest — 21,000 Celestial Coins

These prices are based on the current Early Access information and could change in future updates.
If you are saving for one of these bundles, I recommend checking the in-game shop before making your purchase in case the prices or available options have changed.
Which Fruit Chest Should You Buy?
The best chest depends on how many Celestial Coins you have and what you are trying to do.
If you only have enough for one chest, the 1x Fruit Chest for 1,200 Celestial Coins is the easiest choice. You get a Fruit without having to spend a long time saving for one of the larger bundles.
On the other hand, if you already have a decent Fruit and are specifically trying to get more chances at better Fruits, saving for a larger bundle can make more sense.
Just remember that buying a larger bundle does not guarantee a rare Fruit.
Your results still depend on the game’s Fruit rarity and drop system. For example, current community information lists Darkness as a Celestial Fruit with a 0.5% weight, while Flame is listed as Mythic with a 1.5% weight.
So, even if you save up a large amount of Celestial Coins, do not assume that you are guaranteed to get one of the best Fruits.
Should You Save Celestial Coins for Fruit Chests?
If your main goal is improving your character, I recommend saving your Celestial Coins instead of spending them immediately.
A simple farming routine would look like this:
• Complete purple exclamation quests.
• Check your Logbook achievements.
• Claim any available Celestial Coin rewards.
• Join World Boss events.
• Save your coins.
• Buy a Fruit Chest when you have enough.
• Repeat the process for your next chest.
This makes Celestial Coins a long-term part of your progression rather than something you only think about when you want a new Fruit.
Celestial Coins vs Random Fruit Spawns
There are other ways to get Cursed Fruits in Grand Blue, including random Fruit spawns around the world.
Current information indicates that Fruits can spawn on trees and plants every hour, giving you another opportunity to find one without spending Celestial Coins.
However, random spawns are not particularly reliable if you are looking for a specific Fruit. You could spend a lot of time searching without finding the one you want.
This is where Celestial Coins become useful. Even while you are waiting for random Fruits or doing other activities, you can continue earning coins and eventually exchange them for Fruit Chests.
I would treat random Fruit spawns as a bonus and Celestial Coins as something you can actively work toward.
Best Way to Farm Celestial Coins as a Beginner
If you are still new to Grand Blue, you do not need some complicated farming route.
The easiest approach is to combine Celestial Coin activities with your normal progression.
Here is what I recommend:
• Complete the main quests on your current island.
• Look for NPCs with purple exclamation marks.
• Complete nearby special quests.
• Check your Logbook regularly.
• Claim completed achievements.
• Join World Bosses whenever they appear.
• Save your Celestial Coins for Fruit Chests.
This is much better than stopping your entire progression just to farm coins.
You will naturally complete achievements and quests while leveling anyway, so you might as well collect the extra Celestial Coins along the way.
Celestial Coins and Cursed Fruits
Cursed Fruits are one of the most important parts of combat in Grand Blue. Different Fruits provide different abilities and can work better with certain playstyles.
Current information includes Fruits such as Darkness, Flame, Wolf, Bomb, Chop, Drain, Spike, Strength, Cannon, and Spin.
This is another reason why Fruit Chests can be useful even if you already have a Fruit equipped. You might eventually get something that works better with your build.
However, I recommend being careful before consuming a valuable Fruit. Earlier information suggested that there was no documented way to remove or reroll an eaten Fruit. At the same time, current information indicates that Fruit skill levels are saved separately, so switching between Fruits you own does not necessarily remove their previous progress.
Because Grand Blue is still in Early Access, I would always check the current in-game system before consuming a valuable Fruit.
Should You Spend Celestial Coins Immediately?
For most players, I would not recommend spending your Celestial Coins the moment you get them.
If you are already using a decent Fruit, it can be better to keep saving until you can afford a larger Fruit Chest bundle.
However, there is nothing wrong with buying the smaller chest if you are still early in the game and really need a Fruit for your build.
Here is a simple way to decide:
• Need a Fruit right now: Buy the 1x Fruit Chest.
• Already have a decent Fruit: Save your coins.
• Hunting for rare Fruits: Save as many Celestial Coins as possible.
• Still early in the game: Focus on quests and achievements first.
There is no need to rush. Keep playing normally and your Celestial Coin balance will gradually increase.
Celestial Coins are one of the most useful currencies in Grand Blue, especially if you are trying to build a better collection of Cursed Fruits.
You can earn them in several ways, including Logbook achievements, purple exclamation quests, World Bosses, and other world activities. Because there are multiple sources, you can collect them while doing your normal quests instead of having to dedicate all your time to farming.
For most players, Fruit Chests are the main thing worth saving for. If you need a Fruit immediately, the 1x chest is an easy option, while players who already have a good build may want to save for one of the larger bundles.
Just keep in mind that Grand Blue is still in Early Access. The prices, rewards, Fruit rates, and ways to earn Celestial Coins can change with future updates, so it is always worth checking the current in-game information before spending a large amount of currency.
