If you have reached the later stages of the Third Sea, CDK Blox Fruits is one of the weapon goals you will probably encounter. CDK stands for Cursed Dual Katana, a Mythical sword obtained by completing a series of requirements and trials involving Yama and Tushita. Unlike a sword that you simply purchase from an NPC, CDK requires preparation, mastery grinding, puzzle progression, and a final fight before you can claim it.
For players searching for how to get CDK in Blox Fruits, the most useful thing to know is that you should prepare Yama and Tushita before starting the main Cursed Dual Katana Puzzle. Both swords need 350 Mastery, while your character must be at least level 2200 to begin the puzzle.
Once those requirements are ready, the process becomes much easier to follow.
What Is CDK in Blox Fruits?
Cursed Dual Katana is a Mythical sword that combines the themes of Yama and Tushita into one dual-wield weapon.
That connection is central to the unlock process. Instead of treating CDK as an independent sword, think of it as the reward for proving that you have progressed far enough with both Yama and Tushita.
CDK is particularly attractive to sword-focused players because it offers strong offensive potential and visually distinctive abilities. Meanwhile, PvP players value its movement and combo possibilities.
However, owning a rare sword does not automatically make a build strong. Your stats, Fighting Style, Fruit, accessories, race, player skill, and combo choices still matter.
Therefore, players comparing late-game equipment should consider the blox fruits tier list alongside their preferred playstyle rather than choosing a weapon purely because of rarity.
CDK Blox Fruits Requirements
Before starting the Cursed Dual Katana Puzzle, make sure your character meets the main requirements.
| Requirement | What You Need |
|---|---|
| Character level | Level 2200 or higher |
| Sword 1 | Yama |
| Yama Mastery | 350+ |
| Sword 2 | Tushita |
| Tushita Mastery | 350+ |
| Main location | Third Sea |
| Objective | Complete Yama and Tushita scroll trials |
Getting the two swords is only part of the preparation. Therefore, do not arrive with freshly obtained Yama and Tushita expecting to start immediately.
Instead, grind both to at least 350 Mastery first.
This preparation can take time, so completing it gradually while doing other Third Sea activities is often less repetitive than leaving all 700 combined mastery levels until the end.
How to Get CDK in Blox Fruits
Once you have reached level 2200 and obtained 350 Mastery on both swords, you can begin the main puzzle.
Head to the Crypt Master at the Haunted Castle in the Third Sea. The puzzle area contains two scrolls connected to Yama and Tushita.
Each scroll gives three trials.
As a result, you need to complete six trials in total before reaching the final stage.
The trials are:
Yama Scroll
- Pain and Suffering
- Haze of Misery
- Fear the Reaper
Tushita Scroll
- Dock Legend
- Sense of Duty
- Soulless
These objectives work differently, so read the instructions carefully instead of approaching them as ordinary enemy quests.
Completing the Yama Scroll Trials
The Yama side focuses on three challenges with very different mechanics.
Pain and Suffering
For Pain and Suffering, your character needs to take damage from enemies while using Yama.
Because the objective depends on receiving damage rather than simply defeating targets as quickly as possible, avoid killing everything immediately.
Instead, let enemies attack while keeping Yama equipped and manage your health carefully.
You still need to stay alive, of course. Therefore, use enemies that can damage you consistently without overwhelming your character.
Haze of Misery
Haze of Misery turns the Third Sea into a search challenge.
Certain NPCs become marked, and you need to hunt down the required enemies across different areas.
This trial can take longer because the targets are not necessarily concentrated in one convenient location.
Therefore, mobility helps considerably.
A fast Fruit or movement-focused setup can reduce travel time. For instance, players already using kitsune blox fruits may appreciate strong mobility while moving between distant Third Sea locations, although Kitsune is not required for CDK.
The main goal is simply to locate and eliminate every required marked enemy.
Fear the Reaper
Fear the Reaper requires interaction with the Soul Reaper encounter.
You need a Hallow Essence to summon Soul Reaper at Haunted Castle. Then, instead of defeating the boss normally, the objective involves allowing Soul Reaper to send you to the required trial area.
Because obtaining Hallow Essence may involve some luck and preparation, this can become one of the more inconvenient parts of the Yama path.
Therefore, once you have the required setup, focus on the trial rather than treating Soul Reaper like a normal boss-farming encounter.
Completing the Tushita Scroll Trials
After dealing with Yama’s challenges, the Tushita scroll provides another three objectives.
Dock Legend
Dock Legend is one of the simpler tasks.
You need to interact with Boat Dealers and work through the required dialogue steps.
Compared with combat-heavy trials, this part is straightforward. However, you still need to travel between the appropriate locations.
Therefore, fast movement once again saves time.
Sense of Duty
Sense of Duty sends you into the Pirate Raid at Castle on the Sea.
You need to defeat the required pirate enemies during the raid while progressing the trial.
This objective is more conventional than some of the puzzle stages because it revolves around normal combat.
Still, make sure the correct trial is active before spending time fighting enemies.
If your general build feels weak during late-game content, improving your Fruit, stats, Fighting Style, or equipment can make these objectives smoother. Players using powerful options such as dragon fruit blox fruits may approach combat differently from sword-main builds, so use whatever setup lets you clear enemies reliably.
Soulless
Soulless involves Cake Queen, a boss found in the Third Sea.
The key challenge is defeating Cake Queen under the conditions required by the trial and then completing the following objective correctly.
Because this stage can punish slow damage output, arrive with a build you know how to use rather than experimenting with unfamiliar abilities during the attempt.
After progressing through the trial, pay close attention to the next environment and objective. Puzzle stages are not always solved by simply attacking the first thing you see.
The Final Cursed Dual Katana Puzzle
Once all six scroll trials have been completed, the CDK quest reaches its final stage.
Return to the puzzle area at Haunted Castle and continue the sequence.
You will eventually face the Cursed Skeleton Boss.
Defeat the required enemy to complete the final challenge and claim Cursed Dual Katana.
At that point, the long preparation with Yama and Tushita finally pays off.
If your main goal was searching how to get CDK in Blox Fruits 2026, remember that the core progression is easier to manage when broken into stages: obtain both swords, reach 350 Mastery on each, meet the level requirement, finish all six trials, and clear the final encounter.
Cursed Dual Katana Abilities
Once unlocked, CDK has two sword moves that become available through Mastery progression.
Revolving Ravager
Revolving Ravager is CDK’s Z ability.
The move provides offensive pressure while fitting naturally into close-range sword gameplay.
Its movement and attack properties can make it useful for engaging opponents or extending certain combos, depending on positioning.
However, effectiveness depends heavily on timing. Simply using the ability whenever it comes off cooldown will make your attacks predictable in PvP.
Slayer of Goliath
Slayer of Goliath is CDK’s X ability.
It provides another aggressive attack option and contributes to the weapon’s combo potential.
Together, CDK’s moves give experienced players tools for pressure and movement rather than functioning only as raw damage attacks.
Therefore, practice against NPCs before expecting consistent PvP results.
Best Build Approach for CDK
CDK makes the most sense when your stats support sword damage.
A dedicated Sword Main generally invests heavily in Sword while maintaining enough Defense and Melee for survivability and Energy.
However, hybrid strategies exist.
Your ideal setup depends on whether you want CDK to provide primary damage or serve as one piece of a larger combo involving Fruit and Fighting Style abilities.
For example, a player using gas fruit blox fruits may build combos differently from someone who relies primarily on sword attacks.
Instead of copying a build without context, decide what role CDK should perform.
If the sword provides your main damage, prioritize Sword appropriately. Meanwhile, if you mainly use it for movement, setup, or combo extensions, your stat distribution may look different.
CDK for PvE and Grinding
Cursed Dual Katana can perform well against NPCs once you become comfortable with its moves.
Still, obtaining CDK specifically for basic leveling is unnecessary because you must already be deep into Third Sea progression before unlocking it.
Its real PvE value appears in later-game activities where strong sword damage and useful abilities complement your build.
For mastery farming, group manageable NPCs when practical and use attacks efficiently.
Meanwhile, do not sacrifice survivability just to maximize damage. High-level enemies can punish careless positioning.
CDK in PvP
PvP is where many players become particularly interested in Cursed Dual Katana.
Strong opponents will not simply stand still while you cycle through abilities. Therefore, movement, prediction, stuns, and combo timing become far more important.
Avoid opening every fight with the same CDK move.
Instead, watch how your opponent dodges. Once you recognize their movement habits, use your Fighting Style or Fruit to create openings before committing your sword abilities.
You should also learn the effective range of each move.
Missing an ability can leave you vulnerable, especially against experienced players who immediately counterattack.
Therefore, CDK becomes more dangerous as your mechanical skill improves.
Common CDK Mistakes
One of the biggest mistakes is attempting the quest before preparing both swords properly.
If Yama or Tushita has less than 350 Mastery, finish that grind first.
Another mistake is rushing through trial instructions. CDK is a puzzle-based unlock, so some objectives require specific actions rather than simply defeating an enemy.
Players can also waste time by approaching a required boss incorrectly. Read the current trial objective before fighting.
Meanwhile, connectivity problems can interrupt progress at the worst possible moment. If Roblox repeatedly disconnects before you can complete an objective, troubleshooting roblox error code 279 may help identify connection-related issues before another attempt.
Finally, avoid treating CDK as an instant PvP win button. The sword is powerful in capable hands, but experienced opponents can punish predictable attacks.

Yes, CDK can be a strong PvP weapon because its abilities support aggressive sword combos and movement. However, its performance depends on your build, aim, timing, and ability to create openings.
Is CDK good for beginners?
CDK itself is a late-game weapon, so true beginners will not be able to obtain it immediately. By the time you meet its requirements, you should already understand Third Sea combat and basic build mechanics.
Can you buy CDK with Beli or Robux?
No. CDK is earned through its progression and puzzle requirements rather than simply purchased as a standard weapon.
The Best Way to Approach the CDK Grind
The CDK Blox Fruits quest looks complicated when you view every requirement at once. However, it becomes much easier when you separate preparation from the actual puzzle.
Get Yama and Tushita first, raise each sword to 350 Mastery, and make sure you meet the level requirement. Then, work through the six scroll trials individually instead of trying to rush the entire unlock in one session.
Once Cursed Dual Katana is yours, spend time learning its range and timing rather than immediately jumping into serious PvP. CDK rewards players who understand how its abilities fit into a complete build, and that practice is what turns a rare late-game sword into a genuinely dangerous weapon.
