The Blox Fruits CDK, or Cursed Dual Katana, stands as the pinnacle of swordsmanship in the Third Sea. For any player looking to dominate in PvP or clear high-level raids with ease, obtaining the Blox Fruits CDK is not just a goal—it is a necessity. This Mythical-tier weapon combines the raw, demonic power of Yama with the holy, precise strikes of Tushita, creating a dual-wielding powerhouse that ignores the defense buffs of even the most stubborn Dragon users.
Whether you are a Buddha user looking for the perfect M1 (left-click) weapon or a combo specialist aiming for high-damage stuns, the Cursed Dual Katana is arguably the most versatile tool in your arsenal. However, the path to forging this blade is fraught with complex puzzles, high mastery requirements, and trials that will test your patience. In this comprehensive guide, we will break down every step to ensure you add this legendary weapon to your inventory.
Pre-requisites: Preparing for the Cursed Quest
Before you can even begin the quest for the Blox Fruits CDK, you must prove your worth as a master swordsman. The game enforces strict entry requirements that prevent lower-level players from accessing the Alucard trials.
According to community reports and the official Wiki, you cannot interact with the Crypt Master at the Floating Turtle until you meet the following criteria:

Mastery Grinding Tip
The most efficient way to reach 350 mastery on both swords is to farm the "Cake Guards" or "Big Mom" (Cake Queen) in the Sea of Treats. These NPCs provide massive mastery experience compared to earlier Third Sea enemies.
Step 1: Initiating the Alucard Trials
Once you have reached Level 2200 and secured 350 mastery on both blades, head to the Mansion on the Floating Turtle. Behind the building, you will find a secret entrance leading to the Crypt Master.
Upon speaking to him, he will open a door to a back room containing two pedestals—one for the Tushita Scroll (white) and one for the Yama Scroll (purple). You must complete three trials for each scroll to collect six Alucard Fragments.
Step 2: The Tushita Scroll Trials (The White Scroll)
The Tushita trials focus on your connection to the world and your speed under pressure. Many players find these to be the more "tedious" of the two sets, but they are essential for the Blox Fruits CDK progression.
1. Dock Legend
You must speak to three Boat Dealers across three different islands. While this sounds simple, players often report that the order matters. Start at the Castle on the Sea, then head to the Port Town, and finally visit the Floating Turtle docks. If the dialogue changes to acknowledge your "familiar face," you are on the right track.
2. Sense of Duty
This trial requires you to participate in a "Pirate Raid" at the Castle on the Sea. You don't need to solo the entire raid; you simply need to defeat at least one pirate during the event. Once the raid is cleared and you've contributed, the Alucard Fragment will be yours.
3. Soulless
This is the most difficult Tushita trial. You must defeat the Cake Queen (Big Mom) boss at Ice Cream Land before a specific song ends.
The Timer: As soon as you hit her, a music track starts playing. You have exactly two minutes.
The Twist: Once she dies, you will be teleported to a "Heaven" dimension where you must light three torches and defeat several waves of NPCs.

Step 3: The Yama Scroll Trials (The Purple Scroll)
The Yama trials represent "pain and suffering," fitting for a demonic blade. These trials often involve taking damage or hunting down specific targets across the map.
1. Pain and Suffering
To complete this, you must let an NPC or another player hit you until you have taken roughly 8,000 to 10,000 damage while holding Yama. A common player strategy is to find a group of weak NPCs and simply stand still until the "The scroll reacts to your achievements" message appears.
2. Haze of Misery
This is the trial most likely to frustrate new seekers of the Blox Fruits CDK. Your vision will become fogged with a purple haze. You must travel to every island in the Third Sea and kill specific NPCs that have a purple marking on them.
Pro Tip: Use a fast fruit like Portal or Kitsune to navigate. The markings are visible through walls, so look for the purple glow. You must clear every marked NPC in the world to finish.
3. Fear the Reaper
You must summon the Soul Reaper boss at the Haunted Castle using a Hollow Essence (obtained from the Death King NPC via "Random Surprise").
The Requirement: You must let the Soul Reaper kill you.
The Result: You will be teleported to a "Hell" dimension. Similar to the Tushita trial, you must light three torches and defeat waves of skeletons to earn the final fragment.
Step 4: Forging the Cursed Dual Katana
After collecting all six Alucard Fragments, the two scrolls on the pedestals will burn away. A new pedestal will appear in the center of the room. Placing your fragments here will summon the Cursed Skeleton boss.
This boss uses the moveset of the Blox Fruits CDK, giving you a taste of the power you are about to inherit. Defeat the skeleton using either Yama or Tushita. Once he falls, the two swords will merge, and you will finally receive the Mythical Cursed Dual Katana in your inventory.
Analyzing the CDK Moveset: Why It Dominates the Meta
The reason the Blox Fruits CDK remains a top-tier choice is its ability to stun and its massive hitbox. Unlike many other swords that require pixel-perfect aim, the CDK is forgiving and hits like a truck.
[Z] Revolving Ravager (Mastery 175)
The user spins both katanas, creating a massive tornado.
PvP Utility: If you hold the key, the tornado lasts longer and stuns the opponent. It is an excellent combo starter because it brings the enemy closer to you, allowing for a follow-up with Godhuman or Sanguine Art.
Grinding Utility: The explosion at the end of the spin deals high AoE (Area of Effect) damage, making it great for clearing groups of NPCs.
[X] Slayer of Goliath (Mastery 375)
The user dashes forward with incredible speed, slashing in an "X" pattern.
The Dragon Counter: As noted by the Blox Fruits Wiki, this move specifically ignores the defense buffs of the Dragon Fruit.
Mobility: It can be used as a movement tool to escape combos or close the gap on "runners."

Advanced Combat Tips: Enchantments and Blessings
In a recent community video, high-level players demonstrated the power of the "Frozen" blessing on the Blox Fruits CDK. Because the sword has such high M1 speed, a Frozen blessing can effectively "infinite combo" an opponent by slowing their movement to a crawl between skill cooldowns.
The "Slow Roll" Meta
When using Mythical Scrolls to enchant your CDK, some veteran players suggest a "slow-clicking" technique. Rather than spamming the "Roll" button, waiting for the animation to fully play out is rumored among the community to increase the luck of hitting a Blessing or a Curse. While not statistically proven by the developers, many top-tier bounty hunters swear by it.
Best Pairings for CDK
Buddha Fruit: Since CDK has no forward dash on its M1 attacks, it is the perfect weapon for Buddha users who want to stay stationary while dealing massive damage.
Portal Fruit: The mobility of Portal combined with the long-range "X" dash of the CDK makes you nearly impossible to catch in PvP.
Human V4: The "Psycho" ability of Human V4 increases your damage as your health drops, making the already high-damage CDK capable of one-shotting most players.
Common Mistakes to Avoid
Ignoring Mastery: Many players reach Level 2200 and wonder why the door won't open. You must have 350 mastery on both swords. If you are even one point short, the Crypt Master will ignore you.
Knocking NPCs off the Map: During the Heaven and Hell trials, if you knock an NPC off the floating platforms, they might glitch and not respawn. This can soft-lock your trial, forcing you to restart. Use moves that pull enemies inward rather than pushing them away.
Forgetting to Hold [X]: The Slayer of Goliath move deals significantly more damage and travels further if you hold the button down. Tapping it is only useful for quick finishes.
Comparison: CDK vs. Other Mythical Swords

Conclusion: Is the CDK Still Worth It?
Despite several updates and the introduction of new fighting styles, the Blox Fruits CDK remains a staple of the competitive meta. Its ability to ignore Dragon defense, coupled with the fact that it is free to obtain for any dedicated player, makes it a must-have. The journey through the Alucard trials is difficult, but the reward is a weapon that will carry you through the endgame of the Third Sea.
Start your grind today, focus on your mastery, and soon you will be wielding the most feared dual blades in the world of Blox Fruits.
