The Fist of Darkness in Blox Fruits is the sort of item that can turn a peaceful sailing session into a full-scale emergency. One minute, you are opening chests or hunting Sea Beasts. The next, you are carrying an unstoreable artifact that disappears if you die or leave the server. Suddenly, every nearby player looks suspicious, every connection stutter feels fatal, and even a harmless wall becomes a navigation challenge.
Despite the dramatic name, the Fist of Darkness is not a weapon. It is a rare Second Sea quest item used to summon Darkbeard, begin the Cyborg race puzzle, and unlock the cosmetic Slayer Skin for the Dark Blade. This guide explains where to find it, how to protect it, and which use provides the most value for your character.

What Is the Fist of Darkness in Blox Fruits?
The Fist of Darkness is a special item associated with several important Second Sea activities. Unlike ordinary materials, accessories, and fruits, it cannot be placed in your regular inventory for later use. It remains with your character only during the current session and disappears if you die, disconnect, or deliberately leave the game.
You also cannot drop it for another player or carry two Fists at once. In other words, finding one is only half the mission. The other half is reaching the correct destination without becoming somebody’s surprise bounty donation.

How to Get the Fist of Darkness
There are two legitimate ways to obtain the Fist of Darkness: defeat Sea Beasts or search Second Sea chests. Neither method provides instant results, but one is generally more efficient for active players.
Method 1: Defeat Sea Beasts
Hunting Sea Beasts is usually the best way to farm the Fist of Darkness. Each defeated Sea Beast has an estimated 2.5% chance to drop one. That percentage is not generous, but Sea Beasts can be repeatedly encountered, making this method more active and potentially faster than waiting for a server-aged chest.
Sources:
- Travel to the Second Sea and prepare a suitable boat.
- Sail away from major islands into open water.
- Remain at sea until a Sea Beast event appears.
- Defeat the Sea Beast using attacks capable of reliably hitting sea targets.
- Check whether the Fist of Darkness appears among your rewards.
Fruit users often favor abilities with good range and area coverage. Magma is particularly convenient for sea-event damage, while transformed Buddha users can provide strong sustained pressure when their attacks connect properly. A small group can also kill Sea Beasts more quickly, although coordinating who needs the Fist is wise before the ocean starts throwing monsters at everyone.
Bring a durable boat and avoid standing still unnecessarily. Sea Beast attacks can damage both you and your vessel, and finishing the fight while swimming beside the wreckage of your former transportation is rarely the efficient farming strategy it sounds like.
Sources:
Method 2: Search Second Sea Chests
The alternative method is opening chests. Once a server has been active for about four hours, the Fist of Darkness can appear inside a random chest in the Second Sea. Only the player who opens the correct chest receives it.
This approach works best in a private server because public servers create several unknowns. Another player may already have opened the valuable chest, the server may not be old enough, or a bounty hunter may decide that your rare quest item would look better disappearing from existence.
Sources:
Efficient chest hunters commonly focus on areas with multiple chests close together, such as the Café and Cursed Ship. Portal users have an advantage because they can move rapidly between useful locations. A quick route is more important than randomly sailing from island to island while hoping the correct chest develops a glowing personality.
A chest that already existed without the Fist does not magically gain it while sitting untouched. The relevant chest must spawn with the item, so chest respawns and server age matter. Finding the Fist in a chest for the first time also awards the “Forbidden One” title.

What to Do Immediately After Finding It
The moment you obtain a Fist of Darkness, stop treating the session like a casual farming trip. Decide which objective you are completing and travel there directly.
- Do not leave or switch servers.
- Avoid unnecessary PvP and dangerous NPCs.
- Use safe zones while organizing teammates.
- Check your destination before beginning the trip.
- Do not carry it around while completing unrelated quests.
A private server offers the safest environment. In a public server, disable or avoid PvP when possible and stay away from crowded islands until you are ready. The Fist cannot be stored as insurance, so your best protection is a short, well-planned route.

Use 1: Summon Darkbeard at the Dark Arena
The most direct use of the Fist of Darkness is summoning Darkbeard, a level 1,000 Raid Boss. The Dark Arena is a small Second Sea island located near Snow Mountain and Ice Castle.
- Travel to the Dark Arena.
- Equip or carry the Fist of Darkness.
- Walk into the altar in the center of the arena.
- Prepare to fight as soon as Darkbeard appears.
The server announces the summon with the message, “The power of darkness has been unleashed.” The sky darkens, the screen shakes, and subtlety leaves the server aboard the next available boat. Darkbeard has approximately 305,000 health and disappears after 15 minutes if the group fails to defeat him.
Sources:
Darkbeard Rewards
Defeating Darkbeard can provide approximately 1,500 Fragments, money, levels, and a guaranteed Dark Fragment. He also has a small chance to drop the Dark Coat accessory. Dark Fragments are useful for crafting, fighting styles, and equipment upgrades, so players often need to summon Darkbeard more than once during long-term progression.
Sources:
Tips for Beating Darkbeard
Set your home point at Snow Mountain, Ice Castle, Green Zone, or the Kingdom of Rose before the summon. If you are defeated, a nearby spawn point gives you a chance to return before the raid ends.
Darkbeard uses Dark-based attacks that can pull, stun, and punish players who remain grouped on the ground. Use Instinct, Air Jump, and Flash Step to avoid his Black Hole and Dark Bomb attacks. Maintain enough distance to read his animations, but do not spend the entire fight sightseeing from another island.
A coordinated team is safer than attempting the fight underleveled. Players with powerful Third Sea builds may defeat him alone, but newer Second Sea characters benefit from bringing several allies.

Use 2: Start the Cyborg Race Puzzle
For many players, unlocking the Cyborg race is the best first use of a Fist of Darkness because inserting the item into the Secret Laboratory permanently records that step. Even if you die or change servers afterward, you do not need another Fist for the same Cyborg puzzle.
Sources:
Step 1: Find the Secret Laboratory
Travel to Hot and Cold in the Second Sea and enter the Secret Laboratory on the volcanic side of the island. Locate the dark-blue chamber used for Order raids.
Step 2: Insert the Fist of Darkness
Use the laboratory machine while carrying the Fist. You should receive a message explaining that the Fist has been processed and that a Core Brain is now required.
Insert the Fist before purchasing an Order Microchip. Current puzzle instructions warn that the Fist cannot be inserted while a Microchip is occupying the relevant inventory slot. Buying the chip too early is a small mistake with the emotional impact of stepping on a digital rake.
Sources:
Step 3: Purchase an Order Microchip
Find Arlthmetic inside the hidden section behind the Smoke Admiral’s building and purchase a Microchip for 1,000 Fragments. Use it to begin an Order raid in the Secret Laboratory.
Step 4: Farm Order for a Core Brain
After the Fist has been processed, Order has a 5% chance to drop the Core Brain. You do not have to host every raid yourself, but the Fist insertion must already be registered before the Core Brain can drop for your character.
Because a 5% chance can mean one raid or a small personal documentary about disappointment, gather enough Fragments for multiple attempts and invite players who can defeat Order quickly.
Sources:
Step 5: Unlock the Cyborg Race
Once the Core Brain drops, return to the laboratory machine and insert it. A secret chamber opens. Enter it, speak to the hidden NPC, and purchase the Cyborg race for 2,500 Fragments.
The puzzle remains completed permanently. If you later switch to another race, you can return and buy Cyborg again for 2,500 Fragments without repeating the Fist and Core Brain sequence.

Use 3: Unlock the Slayer Skin for Dark Blade
The third use is intended for dedicated collectors who already own the Dark Blade. Commonly called Dark Blade V3, the Slayer Skin changes the weapon’s appearance and effects to a white-and-black style. It is cosmetic and does not increase the sword’s damage.
The requirements are considerably more demanding:
- Own the Dark Blade.
- Reach V3 or higher with Human, Rabbit, Shark, and Angel.
- Obtain two Fists of Darkness in the same server.
- Use one Fist to summon Darkbeard.
- Use the other at the hidden Graveyard door while Darkbeard is active.
Because one character cannot carry two Fists, this normally requires two players. One player waits near the Graveyard door with a Fist while the other summons Darkbeard at the Dark Arena. The player at the door must interact with its button while holding nothing in hand, although the Fist must remain in the hotbar.
Only one player can unlock the skin per server. Successful completion awards the “Slayer of God” title and allows the skin to be toggled through the rip_indra NPC at Graveyard.

Which Fist of Darkness Use Should You Choose First?
Your best choice depends on your account’s progression:
- Choose the Cyborg puzzle when you have not unlocked Cyborg. The inserted Fist is permanently recorded, making this the safest long-term investment.
- Summon Darkbeard when you need Dark Fragments, Fragments, the Dark Coat, or boss-related progression.
- Attempt the Slayer Skin only after completing its race requirements and arranging a reliable partner.
For an average Second Sea player, Cyborg is usually the smartest first destination. Darkbeard can be summoned with future Fists, while the permanent Cyborg puzzle progress removes a frustrating requirement forever.
Common Fist of Darkness Mistakes
Leaving the Server After Finding It
The Fist disappears when you leave. Do not server-hop after obtaining it, even when another server looks quieter.
Fighting Other Players While Carrying It
This is not the moment to defend your honor against a suspiciously energetic Portal user. Losing the battle also means losing the item.
Buying the Order Microchip Before Inserting the Fist
For the Cyborg puzzle, process the Fist first. Purchase the Microchip afterward.
Expecting to Store or Trade It
The Fist cannot be stored, dropped, or traded like a fruit. Its value comes from immediate use.
Trying to Carry Two Fists Alone
A character can hold only one. The Slayer Skin generally requires a second player or extremely careful coordination involving separate drops.
Summoning Darkbeard Without Preparing
Darkbeard has a 15-minute despawn timer. Assemble your team and set a nearby spawn point before activating the altar.

Frequently Asked Questions
Can the Fist of Darkness be stored?
No. It cannot be placed in normal inventory storage and disappears when you die or leave the server.
What is the fastest way to get it?
Repeatedly defeating Sea Beasts is generally considered the fastest active method. Chest hunting becomes more practical in an older private server with an efficient route.
Does a private server guarantee safety?
It removes interference from random players, but you can still lose the Fist by dying, disconnecting, or leaving.
Can two Fists exist in one server?
Yes, but one player cannot carry both simultaneously. Separate players are normally needed for the Slayer Skin puzzle.
Does inserting the Fist for Cyborg save permanently?
Yes. Once the laboratory processes it, that stage remains completed through deaths, disconnections, and server changes.
Is the Slayer Skin stronger than the normal Dark Blade?
No. It changes the weapon’s visual appearance but provides no additional combat bonus.
A Practical Player Experience: The Hunt, the Panic, and the Payoff
A realistic Fist of Darkness session rarely begins with immediate success. A player usually starts by preparing a sea-event build, buying a dependable boat, and deciding whether the final objective is Darkbeard or Cyborg. That decision matters because wandering around after the drop is the easiest way to transform good luck into a spectacularly preventable disaster.
The first Sea Beast may appear quickly and drop nothing unusual. The second might destroy the boat just as the player is lining up a powerful attack. By the third encounter, the process begins to feel routine: sail into open water, watch the horizon, reposition the boat, dodge the roar, and unload every reliable sea-hitting ability. The Fist’s 2.5% drop rate means several successful hunts can pass without a reward. Random chance has no sympathy and apparently skipped customer-service training.
Experienced hunters make the grind less repetitive by combining methods. They defeat Sea Beasts while periodically checking dense chest areas. The Café is convenient for a quick loop, while the Cursed Ship contains enough nearby chests to justify a visit when the server is old. This does not force the Fist to appear, but it gives the player more meaningful actions than staring at the ocean and negotiating with probability.
When the Fist finally drops, the mood changes instantly. A player who was casually testing attacks five seconds earlier is now checking every direction for bounty hunters. Unnecessary fights stop. Risky shortcuts become less attractive. The destination becomes the only task that matters.
For a first-time owner, taking the item to the Secret Laboratory often creates the best experience. Reaching Hot and Cold safely and inserting the Fist produces immediate relief because that step saves permanently. The player may still need many Order raids to obtain the Core Brain, but the most fragile part of the process is complete. A later disconnect is annoying rather than catastrophic.
A Darkbeard run feels different. Ideally, teammates are already waiting at the Dark Arena before the Fist arrives. Once it touches the altar, the server-wide announcement appears, the sky changes, and every player suddenly remembers that Darkbeard exists. The battle can become visually chaotic as fruit abilities cover the arena, Dark attacks pull players out of position, and late arrivals rush in hoping to contribute enough damage. Defeating him within the timer and receiving the Dark Fragment makes the earlier sea grind worthwhile.
The Slayer Skin creates the most stressful version of the experience. Two players must protect separate Fists, occupy different islands, communicate clearly, and complete their actions before Darkbeard disappears. One mistaken server exit, one PvP ambush, or one player pressing the wrong control can end the attempt. However, that complexity is exactly why the white Dark Blade skin and Slayer of God title feel meaningful to collectors.
The main lesson from these sessions is that preparation beats improvisation. Know the route, prepare the build, gather the required Fragments, and arrange teammates before farming begins. The Fist of Darkness may be controlled by luck, but losing it after the drop is usually controlled by the player.
Conclusion
The Fist of Darkness is one of the most valuable temporary items in the Second Sea. Sea Beast hunting offers the most active farming method, while older-server chest routes provide a slower alternative. Once the item appears, protect it carefully and use it without delay.
Unlocking Cyborg is generally the best first investment because the laboratory records the inserted Fist permanently. Darkbeard is the correct target when you need Dark Fragments and boss rewards, while the Slayer Skin is a challenging cosmetic objective for advanced Dark Blade collectors. Plan before farming, stay out of unnecessary PvP, and never trust a rare-item session to “just one quick detour.” That is how digital tragedies begin.
