The Cursed Dual Katana, or CDK, is a Mythical sword in Blox Fruits on Roblox. It's one of the hardest swords to unlock, because you need two Legendary swords, Yama and Tushita, before you can even start its puzzle.
In this article, we'll explore the CDK requirements, how to get Yama and Tushita, every step of the Cursed Dual Katana puzzle and a few tips to save time.
What Is the Cursed Dual Katana (CDK) in Blox Fruits?
CDK is a Mythical sword from the Third Sea, added in Update 17.3. The Blox Fruits Wiki Cursed Dual Katana page rates it as a strong grinding sword thanks to its high damage and fast M1 attacks.
| Requirement | Detail |
|---|---|
| Sea | Third Sea |
| Level | 2200 or higher to start the puzzle |
| Yama mastery | 350 |
| Tushita mastery | 350 |
| Final boss | Cursed Skeleton Boss, Lv. 2025, 160,000 HP |
| Drop rate | 100% |
Its two moves are Revolving Ravager [Z] at 175 mastery and Slayer of Goliath [X] at 375 mastery, one of the highest mastery requirements in the game.
How to Get Yama and Tushita in Blox Fruits
How to Get Yama
Complete 20 Elite Hunter or Player Hunter quests. The Elite Hunter stands at the Castle on the Sea. At 20 you have a chance to pull Yama, and at 30 it's guaranteed, according to the Blox Fruits Wiki Yama puzzle guide.
Then go to the Secret Temple behind the waterfall on Hydra Island, defeat the Ghosts inside and click Yama until it accepts you. If it rejects you, it kills you, and you can try again after more quests.
How to Get Tushita
You need Lv. 2000 to start the Tushita puzzle, and rip_indra True Form has to be alive in your server. Here are the steps from the Blox Fruits Wiki Tushita puzzle guide:
- Summon rip_indra
Anyone in the server can summon him with a God's Chalice. He only needs to be alive when you enter the gate.
- Open the Secret Temple gate
Go behind the waterfall on Hydra Island, defeat the Ghosts, take the opened passage and walk through the glowing gate.
- Light 5 torches in 5 minutes
You land on Floating Turtle with a Holy Torch. Light the 5 torches in order before the timer runs out.
- Defeat Longma
A door opens near the Fishman enemies. Land the last hit on Longma and Tushita drops at a 100% rate.
The wiki recommends a private server or PvP turned off for these puzzles, since other players can still kill you mid-puzzle.
How to Get CDK in Blox Fruits: The Full Puzzle
Once Yama and Tushita both hit 350 mastery and you're Lv. 2200, talk to the Crypt Master next to the stone building on the hill behind the Mansion. Inside are two scrolls with 3 trials each, and you must hold the matching sword for each one. This follows the Blox Fruits Wiki CDK puzzle guide.
Yama Scroll Trials
| Trial | What to do |
|---|---|
| Pain and Suffering | Take 8,000 to 10,000 damage while holding Yama |
| Haze of Misery | Defeat every NPC with a purple mark across the Third Sea |
| Fear the Reaper | Summon the Soul Reaper with a Hallow Essence and let it defeat you. In the Hell Dimension, light 3 torches and defeat every NPC, including Hell's Messenger |
Tushita Scroll Trials
| Trial | What to do |
|---|---|
| Docks Legend | Talk to 3 Boat Dealers or Luxury Boat Dealers on 3 islands and pick "Pardon me" on the last page of boats |
| Sense of Duty | Defeat 1 enemy from a Pirate Raid at the Castle on the Sea |
| Soulless | Hit the Cake Queen and defeat her within 2 minutes. In the Heaven Dimension, light the torches and defeat every NPC, including Heaven's Guardian |
Defeat the Cursed Skeleton Boss
When both scrolls burn, use the pedestal. A wall opens and the Lv. 2025 Cursed Skeleton Boss appears. Only Yama and Tushita can damage it. CDK drops at a 100% rate, and the wiki notes you still get it even if the boss defeats you.
Tips to Finish the CDK Puzzle Faster
Finished trials save across servers, but progress inside a trial doesn't. Only start a trial when you have time to finish it.
For Haze of Misery, the wiki suggests this route: Port Town, Hydra Island (check the Secret Temple too), Great Tree, Floating Turtle, Haunted Castle and the Sea of Treats. NPCs on Tiki Outpost and Submerged Island are never marked, so skip them.
There's no code or shortcut for CDK. Scripts and auto-farms break Roblox's rules, and sites that ask for your Roblox password to unlock swords are scams.
FAQ
What level do you need for CDK in Blox Fruits?
Lv. 2200 to start the Cursed Dual Katana puzzle. Tushita needs Lv. 2000, and you must be in the Third Sea.
Can you get CDK without Yama and Tushita?
No. You need both swords at 350 mastery to read the scrolls, and only Yama or Tushita can damage the Cursed Skeleton Boss.
Is the CDK drop guaranteed in Blox Fruits?
Yes. The Cursed Skeleton Boss drops CDK at a 100% rate once you finish both scrolls.
Final thoughts
Getting CDK is a long grind: Yama, Tushita, 350 mastery on both and 6 trials before the final boss. Do the hardest trials in a private server, use the Haze of Misery route above, and the Cursed Skeleton Boss gives you the sword at a 100% rate.
