CDK Overview & Why You Need It {#cdk-overview}

Why CDK is Meta in 2025

The Cursed Dual Katana stands out as a top-tier weapon in the November 2025 meta for several critical reasons:

  • Ken-Breaking Capability: The [X] Slayer of Goliath move bypasses Instinct dodges, countering the defensive meta
  • Hybrid Build Synergy: Works exceptionally with Godhuman, Electric Claw, and Sanguine Art fighting styles
  • Dragon/Buddha Counter: Specifically designed to bypass transformation defenses
  • PvP Dominance: Appears in 80% of competitive S-Tier builds as of November 2025
  • Fast Cooldowns: 9-second and 14-second cooldowns enable relentless pressure

Current Meta Position: S-Tier for PvP | A-Tier for PvE (as of November 6, 2025)

Source: According to Blox Fruits Wiki and Dexerto’s Sword Tier List, CDK consistently ranks in the top 3 swords for competitive play.

Requirements Checklist {#requirements}

Before starting the CDK quest, verify you meet ALL of these prerequisites:

Essential Requirements

Requirement Details How to Check
Player Level 2200+ Open stats menu (M key)
Yama Mastery 350+ Equip Yama, check top-right
Tushita Mastery 350+ Equip Tushita, check top-right
Third Sea Access Unlocked Must have completed Second Sea
Recommended Stats 2000+ Melee or Sword For boss fight

Preparation Checklist

Before beginning the puzzle, gather these items to save time:

  • ✅ Hallow Essence (for Fear the Reaper challenge) - farm at Haunted Castle
  • ✅ Combat-ready build (Godhuman + high DPS fruit recommended)
  • ✅ Portal Fruit (optional but highly recommended for Haze of Misery)
  • ✅ Private Server (recommended to avoid interruptions during puzzle)

Time Investment: Expect 4-6 hours total if you don’t own Yama or Tushita yet. If you already have both at 350 mastery, the puzzle alone takes 1.5-2 hours.

Step 1: Getting Yama Sword {#getting-yama}

Yama is one of two prerequisite swords required for CDK. You must obtain it first and train it to 350 mastery.

Yama Requirements

  • Location: Secret Temple on Hydra Island (Third Sea)
  • Level Requirement: 1500+ (for Third Sea access)
  • Quest Prerequisite: Complete 20-30 Elite Hunter or Player Hunter quests

Yama Acquisition Steps

  1. Travel to Hydra Island in the Third Sea
  2. Locate the Secret Temple (hidden behind waterfall near the center)
  3. Complete 20-30 Elite Hunter quests at the Tavern:
    • These quests require you to defeat players or Elite Pirates
    • PvP-focused quests; use private servers to fight alt accounts if needed
  4. Solve the Yama Puzzle at Secret Temple:
    • Find and activate hidden switches in specific order
    • Light torches in correct sequence (varies per server)
  5. Obtain Yama from the shrine after puzzle completion

Yama Moveset

Move Mastery Cooldown Energy Effect
[Z] Hellish Slash 150 9 sec 20 Spinning slash with knockback
[X] Infernal Hurricane 300 14 sec 30 Dashing tornado slashes (breaks Instinct)

Grinding Yama to 350 Mastery

Fastest Mastery Farming Locations:

  • Levels 1500-1800: Great Tree NPCs (consistent spawn rate)
  • Levels 1800-2200: Cake Queen raid (high XP per kill)
  • Levels 2200+: Tiki Outpost (dense NPC clusters)

Pro Tips:

  • Use Buddha fruit for survivability during mastery grinding
  • Equip 2x Mastery gamepass if available (reduces time by 50%)
  • Use Soul Guitar for crowd control while grinding Yama mastery

Estimated Grinding Time: 2-3 hours with Buddha + 2x Mastery; 5-6 hours without gamepass

Step 2: Getting Tushita Sword {#getting-tushita}

Tushita is the second prerequisite sword for CDK. It’s generally easier to obtain than Yama but still requires a puzzle.

Tushita Requirements

  • Location: Floating Turtle (Third Sea)
  • Level Requirement: 2000+ (recommended for Longma boss)
  • Boss Fight: Defeat Longma (Level 2000)

Tushita Acquisition Steps

  1. Travel to Floating Turtle in Third Sea (northeast of the map)
  2. Locate the Tushita Shrine (inside the turtle’s shell, upper level)
  3. Complete the Tushita Puzzle:
    • Find 4 hidden torches around Floating Turtle
    • Light all torches within time limit (5 minutes)
    • Torch locations:
      • Torch 1: Near Musketeer Pirates spawn
      • Torch 2: Behind the large tree (requires climbing)
      • Torch 3: Inside cave system (underwater entrance)
      • Torch 4: Top of turtle’s head (highest point)
  4. Defeat Longma Boss:
    • Level: 2000
    • HP: ~250,000
    • Attacks: Fast sword slashes, Instinct-breaking combos
    • Strategy: Use ranged fruit + Godhuman, dodge backward after 3-hit combos
  5. Claim Tushita from the shrine after Longma’s defeat

Tushita Moveset

Move Mastery Cooldown Energy Effect
[Z] Heavenly Lunges 150 9 sec 15 Rapid stabs with stun + final lunge
[X] Celestial Ravager 300 14 sec 30 High-speed dash with red X-slashes

Grinding Tushita to 350 Mastery

Same farming locations as Yama (see above). Tushita’s faster attack speed makes it slightly more efficient for mastery grinding.

Estimated Grinding Time: 2-3 hours with 2x Mastery; 4-5 hours without

Step 3: The 6-Challenge Puzzle {#the-puzzle}

Once you have both Yama and Tushita at 350+ mastery and are Level 2200+, you can begin the CDK puzzle. This is the most complex quest chain in Blox Fruits.

Accessing the Puzzle

  1. Go to Floating Turtle in the Third Sea
  2. Find the Mansion (large building near center)
  3. Behind the mansion, locate the stone building on the hill
  4. Speak with Crypt Master NPC
  5. Select “I wish to enter” to unlock the crypt door

Inside the Crypt

You’ll find two scrolls:

  • Left Scroll (Red): Yama Challenges (3 trials)
  • Right Scroll (Blue): Tushita Challenges (3 trials)

You must complete all 6 challenges. They can be done in any order, but completing one scroll’s challenges before starting the other is recommended to track progress.

Yama Scroll Challenges {#yama-scroll}

Challenge 1: Pain and Suffering

Steps:

  1. Equip Yama sword

  3. Remove armor/accessories to take more damage
  4. Let enemies attack until you reach ~8,000-10,000 total damage taken
  5. Return to the crypt - the challenge completes automatically

Time Required: 15-25 minutes

Step 4: Defeating Cursed Skeleton Boss {#boss-fight}

After completing all 6 challenges, both scrolls will burn. Return to the pedestal in the crypt to trigger the final boss.

Cursed Skeleton Boss Stats

  • Level: 2025
  • HP: ~400,000 (estimated)
  • Special Mechanic: Can ONLY be damaged by Yama or Tushita swords
  • Attacks: Fast sword combos, Instinct-breaking slashes, shadow teleports

Boss Fight Strategy

Preparation:

  • Equip either Yama or Tushita (not CDK, you don’t have it yet!)
  • Use Godhuman or Sanguine Art fighting style for combos
  • Bring healing accessories (Leviathan Shield, Kitsune Ribbon)
  • Enable Instinct (V) for dodge warnings

Combat Tips:

  1. Phase 1 (100%-50% HP):

    • Cursed Skeleton uses basic sword combos
    • Dodge backward after 3-hit strings
    • Use Yama/Tushita [Z] moves on cooldown
    • Mix in fighting style combos between sword attacks

  2. Phase 2 (50%-0% HP):

    • Boss gains shadow teleport ability
    • Red warning appears before teleport strikes - dodge immediately
    • Increase use of ranged attacks (Tushita [X] is safer than Yama [Z])
    • Stay mobile, don’t stand still

Optimal Combo:

Tushita [Z] (Heavenly Lunges) → Godhuman [C] → Godhuman [X] →
Tushita [X] (Celestial Ravager) → Godhuman [Z]

Time to Defeat: 3-5 minutes with optimized build

⚠️ Important Note

After completing all 6 challenges, you can actually disconnect and rejoin - the game will give you CDK without fighting the boss! This is a known mechanic as of November 2025.

However, if you want the full experience and boss drops, stay and fight.

Frequently Asked Questions {#faq}

Can I get CDK without fighting the boss?

Yes. As of November 2025, if you complete all 6 challenges and disconnect before fighting Cursed Skeleton, the game will grant you CDK when you rejoin. This appears to be an intentional mechanic to prevent griefing.

How long does the entire CDK quest take?

  • With Yama/Tushita ready: 1.5-2 hours for puzzle
  • From scratch: 6-8 hours total (includes farming 350 mastery on both swords)
  • With Portal fruit: Can reduce puzzle time by 30-40 minutes

Do I need both Yama and Tushita equipped?

No. You only need 350 mastery on both. You can store one in your inventory during the puzzle. For the final boss, you can use either Yama OR Tushita.

What happens if I disconnect during the puzzle?

  • Yama challenges: Pain and Suffering and Fear the Reaper progress is saved
  • Haze of Misery: ⚠️ RESETS completely (you must restart)
  • Tushita challenges: All progress is saved

Is CDK still meta in November 2025?

Yes. CDK remains S-Tier for PvP due to:

  • Ken-breaking [X] move counters Instinct-heavy builds
  • Synergy with Godhuman/Sanguine Art/Electric Claw
  • Appears in 80% of competitive top 100 player builds

However, for pure PvE grinding, Dragon Trident and True Triple Katana are now preferred.

Can I trade CDK?

No. CDK is untradeable and permanently bound to your account. Every player must complete the puzzle themselves.

What’s the best fruit for getting CDK?

Recommended fruits:

  1. Portal - for Haze of Misery (teleportation)
  2. Buddha - for survivability during boss fights
  3. Dough V2 - for Sense of Duty raid (high DPS + survivability)

Avoid using Chop, Bomb, or low-tier fruits - the puzzle has multiple boss fights.

Conclusion

The Cursed Dual Katana remains one of the most rewarding weapons to obtain in Blox Fruits, despite its lengthy acquisition process. The combination of Ken-breaking abilities, defense bypass mechanics, and synergy with top-tier fighting styles makes it essential for competitive PvP in the November 2025 meta.

Total Time Investment: 6-8 hours from scratch; 1.5-2 hours with prerequisites complete

Difficulty Rating: 8.5/10 (requires puzzle-solving, boss fights, and extensive preparation)

Meta Viability: S-Tier for PvP, A-Tier for PvE

Good luck on your CDK journey! Remember to use private servers for uninterrupted progress, bring Portal fruit for Haze of Misery, and don’t forget to equip Yama or Tushita for the final boss.
