Getting the Cursed Dual Katana (CDK) in Blox Fruits requires mastering multiple demanding puzzles, maxing out your swords, and defeating fearsome Raid Bosses. It's one of the toughest weapons to earn in the game, but its insane damage output and mobility make the grind completely worth it.
If you're tired of wandering around Third Sea without knowing exact stat requirements or puzzle locations, you're in the right place. Let's break down the exact prerequisites, torch puzzles, dimension trials, and boss fights needed to forge this legendary weapon.
Prerequisites and Preparation
Before you can even touch the first puzzle, your character and swords must meet strict minimum standards. Skipping these will leave you stuck halfway through the quest line.
- Level Requirement: You must be at least Level 2200 to access the Third Sea areas and start the quest.
- Mastery Requirement: Both your Tushita and Yama swords must be at 300 Mastery or higher. If either sword falls short, the quest triggers won't activate.
- Haki Requirement: Having Observation V2 fully unlocked helps immensely during the trial phase, though it's technically optional if your timing is immaculate.
Make sure your inventory is stocked with crafting materials and you have a reliable crew to help spawn and defeat floating island bosses.
Obtaining Yama and Tushita
You can't forge the dual blades without first acquiring their single components. Yama and Tushita require separate, lengthy quest chains to unlock.
Securing the Yama Sword
Yama drops from the Hydra Island secret area. You'll need to defeat Elite Pirates until you collect enough Elite Hunter quests to unlock the hidden cave behind the waterfall.
- Head to Hydra Island and find the waterfall.
- Walk through the water to enter the hidden chamber.
- Interact with the pedestal holding Yama. You'll need to pull it multiple times. Be warned: if you haven't completed enough Elite Hunter quests, pulling the sword will instantly kill your character.
- Once you meet the kill threshold, pulling the sword successfully adds it to your inventory.
Securing the Tushita Sword
Tushita requires defeating the Longma boss or completing the intricate torch puzzle during the Rip_Indra raid boss spawn in Castle on the Sea.
- During the Rip_Indra boss fight, a secret passage opens on the side of the castle island.
- Enter the dark room and quickly light all five torches scattered across the floating platforms before the timer runs out.
- Defeat Longma at the end of the secret path inside the Floating Turtle island to claim Tushita.
Starting the Cursed Dual Katana Quest
Once Tushita and Yama both sit at 300+ mastery, travel to the Floating Turtle island and locate the hidden dimension room behind the waterfall near the Musketeer Pirates.
Find the ghostly NPC huddled in the corner. Interacting with him activates three distinct torch trials. Each trial tests your precision, speed, and combat endurance.
The Floating Turtle Torch Trials
You'll be teleported into specific testing areas representing fear, pain, and destruction.
- The Trial of Fear: Navigate a pitch-black maze using a torch that burns down over time. Lighting sconces along the walls extends your timer. Missing a single corner means restarting from scratch.
- The Trial of Pain: You must survive waves of high-level enemies while your health steadily drains. Bring your best defensive accessories and high-damage area-of-effect fruits like Buddha or Mammoth to clear mobs quickly.
- The Trial of Congruence: Solve a color-coded island alignment puzzle by matching platform NPCs with the correct faction banners. Take your time here; rushing leads to misaligned tiles and immediate failure.
Defeating the Dimension Bosses
Surviving the trials brings you face-to-face with the trial bosses. You must defeat them inside the separate dimension to prove your worthiness.
- Use high-mobility movement abilities to dodge the boss's screen-wide projectile attacks.
- Keep your health above fifty percent by utilizing life-steal accessories or fighting styles like Godhuman.
- Once the boss falls, you'll receive a colored fragment confirming the completion of that specific sword's trial path.
The Final Crafting Phase
With both trial fragments secured and your mastery locked in, head back to the cryptic stonemason NPC near the Floating Turtle docks.
He'll inspect both Tushita and Yama, extract the cursed energy from each blade, and fuse them together. This final interaction costs a hefty sum of in-game cash and fragments, so make sure your wallet is full before triggering the cutscene.
Common Mistakes to Avoid
Many players fail their first attempts due to simple oversights. Keep these pitfalls in mind during your run:
- Ignoring Mastery Levels: Trying to start the quest with a 299 mastery sword wastes hours of setup. Double-check your stats in the menu.
- Rushing the Maze: In the Trial of Fear, running too fast causes you to miss side rooms with essential torch refills. Pace your movements steadily.
- Going Solo on Bosses: While possible alone, fighting dimension bosses with a couple of trusted crewmates cuts down clear times and prevents frustrating wipes.
Frequently Asked Questions
Can I do the Yama and Tushita quests in any order?
Yes. As long as both swords reach 300 mastery, you can tackle Yama and Tushita in whatever sequence fits your current level progression.
What happens if I die during the torch trials?
Dying inside the trial dimensions fails the run immediately. You'll have to return to the quest giver and restart that specific trial from the beginning.
Is the Cursed Dual Katana better than Dark Blade?
Both weapons excel in different scenarios, but CDK boasts some of the highest base damage scaling and combo potential for PvP in the entire game, making it a favorite for bounty hunters.
Do I lose my sword mastery if I fail a trial?
No, your weapon mastery remains untouched. Only your progress inside the active trial dimension resets upon death.
