How to Get the Cursed Dual Katana in Blox Fruits

The Cursed Dual Katana (CDK) is one of the most powerful and visually striking swords in Blox Fruits, often considered the best blade for high-level sword mains. However, obtaining it isn't simple—it's a lengthy, puzzle-based quest that requires mastery, patience, and a solid understanding of both Yama and Tushita swords. Here's a detailed walkthrough on how to earn the CDK and prove your worth as a true swordsman.

Requirements

Once you meet these conditions, you'll gain access to the Crypt Master behind Turtle Mansion—this is where your journey begins.

Beginning the Quest: The Crypt Master

Go behind the Turtle Mansion on Third Sea and locate a tall, vine-covered tower. On its left side stands the Crypt Master NPC. After you speak with him, a hidden passage opens on the opposite side of the tower. Inside are two pedestals:

• The Tushita Scroll (white lantern side)
• The Yama Scroll (red lantern side)

You'll need to complete three trials for each scroll before unlocking the Cursed Dual Katana chamber.

Tushita Scroll Trials

1. Dock Legend Trial 
Interact with the Tushita scroll to begin. You'll need to say “Pardon me” to three Luxury Boat Dealers located on different islands. Doing so correctly rewards an Alucard Fragment.

2. Sense of Duty Trial 
Join a Pirate Raid event (occurs every 1 hour and 15 minutes) and defeat at least one pirate. Make sure to reactivate the quest each time you switch servers, or progress won't count. Completing this also grants an Alucard Fragment.

3. Soulless Trial 
Activate the trial, then defeat the Cake Queen Boss at Ice Cream Land. Upon victory, you'll teleport to a Heavenly Dimension—light all three torches and defeat the enemies that spawn. After completing this challenge, the Tushita Scroll burns away, signaling success.

If you're aiming to master the Cursed Dual Katana challenge efficiently, preparation is key—gather strong allies, optimized builds, and the right gear before attempting these trials. For players looking to upgrade faster, the best place to buy Blox Fruits items is from trusted online stores that offer secure and instant delivery, helping you focus on perfecting your sword skills instead of grinding endlessly.

Yama Scroll Trials

1. Pain and Suffering Trial 
While wielding Yama, take continuous damage from players or enemies until you earn an Alucard Fragment.

2. Haze of Misery Trial 
Defeat enemies across Third Sea that glow with a pink or purple aura. It's a long process, so persistence is key. Once all are cleared, the fog surrounding your screen will vanish, and you'll earn your next fragment.

3. Fear the Reaper Trial 
This one's particularly challenging. You must die to the Soul Reaper Boss, which can only be summoned using a Hallow Essence (obtained by praying at gravestones or rolling with bones). When killed, you'll enter the Hell Dimension—light three torches, survive waves of enemies, and destroy the Yama Scroll.

The Final Step: Claiming the Cursed Dual Katana

After both scrolls are completed, a pedestal appears before the blocked passage inside the Crypt Master's tower. Interact with it to summon the Cursed Skeleton Boss—the final gatekeeper. 
You can only damage this boss using Yama or Tushita—no other sword or fruit works. Upon defeating it, you'll automatically receive the Cursed Dual Katana with a 100% drop rate.

Summary

The Cursed Dual Katana quest is long, multi-staged, and filled with difficult combat encounters, but it's worth every step. Between two dimensions, six trials, and multiple bosses, it serves as the ultimate test of a sword user's patience and mastery in Blox Fruits. Once completed, you'll hold one of the strongest weapons in the game—proof of your dedication to swordsmanship.
