This sword — universally known in the community as CDK — is the most prestigious and sought-after sword in the entire game. It is rated S+ Tier in the Update 29 meta, serves as the centerpiece of endgame sword-main builds, and is a status symbol that tells every player you have completed one of the most challenging multi-step quests in Blox Fruits. This guide covers every prerequisite, all 6 Scroll Trials, and how to use CDK at its full potential.
CDK Requirements – What You Need Before Starting in Blox Fruits
⚔️ CDK Prerequisites Checklist
- Player Level 2200 or higher
- Tushita sword in inventory (obtained from Longma boss after torch puzzle)
- Yama sword in inventory (obtained from Elite Hunter after defeating 30 Elite Pirates)
- 350 Mastery on Tushita
- 350 Mastery on Yama
- Portal fruit strongly recommended for movement during trials
Budget 20–40 hours total farming time for all CDK prerequisites combined. Yama requires defeating 30 Elite Pirates (random spawns with low probability across Third Sea islands) plus purchasing from the Legendary Sword Dealer for 2M Beli. Tushita requires completing the full torch puzzle and defeating Longma. Both must then reach 350 Mastery before the CDK quest can begin.
How to Get Cursed Dual Katana in Blox Fruits – Step by Step
Find the Crypt Master at Floating Turtle
Go to the Floating Turtle Mansion in the Third Sea. Do not enter through the main entrance. Walk around the building to find the Crypt Master NPC on the left side near the big stone Crypt building. Interact with him — he will open the door to the Crypt.
Enter the Crypt and Read the Scrolls
Inside the Crypt there are two pedestals — Tushita Scroll (white lanterns, left side) and Yama Scroll (red lantern, right side). Each scroll has 3 Trials. You must complete all 6 Trials across both scrolls. The order does not matter — most players complete Tushita Scroll first since its trials are easier.
Complete Tushita Scroll Trials (3 Trials)
Trial 1 (Docks Legend): Interact with 3 different Luxury Boat Dealers on 3 different islands using the "Pardon me" dialogue. Trial 2: Involves completing a Tushita-themed challenge (refer to current community walkthrough for exact steps as these can vary by update). Trial 3: Final Tushita trial leads to a boss fight — defeat it to burn the Tushita Scroll.
Complete Yama Scroll Trials (3 Trials)
Trial 1 (Haze of Misery): Kill every enemy NPC with a purple marking across all Third Sea islands. Vision becomes hazy and remains that way until complete — the most time-consuming trial in the CDK quest. Progress is NOT saved on disconnect — complete in a private server. Trial 2 and 3: Continue Yama Scroll challenges. Burning both scrolls concludes the puzzle.
Defeat the Cursed Skeleton Boss
After burning both scrolls, interact with the pedestal inside the Crypt to open a wall. Walk through the red circle to reveal the Cursed Skeleton Boss (Level 2025). IMPORTANT: The Cursed Skeleton can ONLY be damaged using Tushita and Yama swords — no other weapons or fruit abilities deal damage to it. Defeat it to receive the CDK at 100% drop rate.
Critical Warning: The Haze of Misery trial (kill all purple-marked NPCs across Third Sea) does NOT save progress on server disconnection. If you disconnect during this trial, you must restart from the beginning. Complete the entire CDK puzzle in a private server to avoid losing hours of progress to disconnection.
Cursed Dual Katana Moves in Blox Fruits
The user spins rapidly, forming a red and black tornado that stuns and damages enemies. Can be thrown to pull enemies in and explode on contact. Holding the key increases damage output. Fastest stun engage tool in the CDK kit — as fast as Dark Blade's X move but with better range according to the wiki. Use this to initiate combos and break opponent Instinct before the full rotation.
Forms an X with the swords and dashes toward the enemy. Holding the button extends the dash range. On contact, a spinning X mark appears blocking vision and dealing massive burst damage. Excellent pressure move and raw damage dealer — the key burst move in CDK combos after the Revolving Ravager stun lands.
CDK vs True Triple Katana – Why CDK Wins in 2026
The True Triple Katana is still a very strong sword — third-highest M1 damage in the game, excellent Dragon Hurricane AoE, and solid combo potential. But CDK surpasses it in key areas that matter for competitive 2026 play: faster move execution, more combo routes, higher burst on Slayer of Goliath, and Revolving Ravager's pull mechanic which TTK has no equivalent of.
The most meaningful practical difference is the M1 dash — TTK has a dash on the fourth M1 click which complicates grinding and repositioning during combos. CDK has no M1 dash, making it cleaner for both grinding with Buddha and maintaining aggressive combo pressure in PvP. This absence of the dash is consistently cited by sword mains as the primary quality-of-life improvement CDK provides over TTK in actual play. The 20–40 hour investment to obtain CDK is significant, but most endgame players who complete it report never going back to TTK as their primary sword.
Blox Fruits Cursed Dual Katana PvP Build and Best Pairings
CDK is the consensus best sword for PvP in 2026 and S+ Tier in the Update 29 meta. It is a requirement for top-100 bounty hunters and widely considered the defining endgame sword for sword mains. The standard stat distribution is 2550–3000 in Sword, 3000 Defense, and 3000 Melee (for energy to sustain full combo chains).
Dough and Ice are the top fruit pairings for CDK — their stun mechanics lock opponents in place before the CDK rotation begins. Godhuman and Sanguine Art are the recommended fighting styles. Always lead with Revolving Ravager to break Instinct before committing to Slayer of Goliath — the Z → X combination is CDK's standard combo opener. For fruit matchups that work alongside CDK's sword-dominant playstyle, see our Love vs Spirit guide for Natural fruit options. Our Pain vs Shadow guide covers budget Natural fruit pairings for CDK builds. For fruit choices that complement the CDK's area control strengths, check our Control vs Gravity guide. Verify current CDK ability data on the Blox Fruits Fandom Wiki and check event status on Roblox.com.
CDK Grinding Note: CDK is rated excellent for grinding — its high damage M1 attacks are very compatible with Awakened Buddha, and it has no dash on M1 (unlike TTK). For AoE mob grouping, use Bane of Souls or Six Paths before activating Revolving Ravager to clear grouped enemies. CDK recovers its investment in significantly reduced grinding time per session.
CDK Grinding Efficiency in Blox Fruits
One of CDK's most underappreciated strengths is grinding efficiency. Unlike the True Triple Katana which has a dash on the fourth M1 click, CDK's M1 attacks are clean and stationary — making it significantly better for Buddha grinding builds where consistent close-range damage output is the priority. Combined with Awakened Buddha's large hitbox and defense, CDK becomes one of the most efficient grinding setups available in the Third Sea.
Bane of Souls is CDK's designated mob grouping move for grinding sessions — pulling nearby enemies into a cluster before activating Revolving Ravager or Slayer of Goliath for AoE clearing. The combination eliminates the need for an external pulling mechanic and keeps the CDK as the primary tool for both grouping and clearing. At max stat distribution (3000 Sword, 3000 Defense, 3000 Melee), CDK with this loop reaches Sheckle-per-hour rates that compete with the top-tier fruit grinding setups in the game's Third Sea content.
