Why Cursed Dual Katana is the Best Sword

Cursed Dual Katana (CDK) is universally considered the strongest and most desirable sword in Blox Fruits. Its moves have excellent range, damage, and combo potential, making it dominant in both PvP and PvE content. The Z move is a fast stun that initiates combos perfectly. The X move deals massive damage with good AoE. The C move provides mobility while dealing damage. When paired with top-tier fruits like Dough or Leopard, CDK enables the highest-damage combos in the game. However, obtaining CDK is one of the most time-consuming challenges in Blox Fruits. It requires combining two extremely rare swords—Yama and Tushita—each of which requires significant grinding. Plan for 20-40 hours of total farming time, depending on luck and experience. Despite the difficulty, CDK is worth pursuing if you're serious about end-game content. Let's break down exactly how to get it.

Step 1: Obtaining Yama Sword

Yama is one of the two legendary swords needed for CDK. Here's how to get it: Requirements: Level 2300+, access to Third Sea, 2 million Beli. The Grind: You must defeat 30 Elite Pirates in Third Sea. Elite Pirates are special NPCs that spawn randomly across Third Sea islands. They're distinguished by their red aura and are significantly stronger than regular NPCs. Finding Elite Pirates: Elite spawns are random with low probability. Server hop to find them—each server has independent spawn timers. Check popular islands: Floating Turtle, Haunted Castle, Sea of Treats. Once you spot an Elite, mark their location and check back periodically. Speed Tips: Join Elite hunting Discord groups where players share spawn locations. Use Light fruit for fast travel between islands. Check all three floors of multi-level islands. Elites respawn approximately every 10-15 minutes per server. After defeating 30 Elite Pirates, find the Legendary Sword Dealer (spawn location varies) and purchase Yama for 2 million Beli. The counter tracks across multiple sessions, so you don't need to defeat all 30 in one sitting.

Step 2: Obtaining Tushita Sword

Tushita is the second legendary sword, obtained through a complex puzzle during full moon. Requirements: Level 2300+, full moon night, completion of the torch puzzle, defeat of Longma boss. The Torch Puzzle: During full moon (use our Full Moon Calendar), six hidden torches spawn across Third Sea. You must light all six torches in the correct order before the full moon ends. Torch Locations: The torches spawn at specific locations that never change. Look up a torch location guide or video—memorizing these saves significant time. Torch Order: The activation order is displayed on a stone tablet. Find the tablet, note the order, then light torches in that sequence. Timing: You have limited time during the full moon. Practice the route beforehand, know exactly where each torch is, and use fast travel methods (Light fruit, flying abilities). After Torches: Completing the torch sequence opens access to Longma's lair. Fight Strategy: Longma is a challenging boss with multiple phases. Bring a crew if possible. Buddha fruit provides good survivability. Learn his attack patterns—he telegraphs most moves. Victory grants Tushita sword. The entire Tushita process takes 30-60 minutes per attempt, but you only get one attempt per full moon cycle.

Step 3: Combining Swords into CDK

With both Yama and Tushita in your inventory, you can now forge Cursed Dual Katana. Location: The Cursed Ship in Third Sea. This is the same ship where you fought Cursed Captain during the Soul Guitar quest. Finding the Secret Room: Enter the Cursed Ship and navigate to the lower decks. Look for a hidden passage that leads to a ceremonial chamber. The room contains an altar where legendary swords are forged. The Combination: Approach the altar with both swords in your inventory. Interact with the altar and confirm the combination. You will permanently lose Yama and Tushita, receiving Cursed Dual Katana in exchange. Important Warning: This action is irreversible. You cannot separate CDK back into Yama and Tushita. Make absolutely sure you want CDK before combining. After Receiving CDK: The sword comes at mastery 0. You'll need to grind mastery using our strategies from the Mastery Guide to unlock all moves. CDK mastery 600 takes approximately 5-8 hours with optimal methods. Congratulations! You now own the most powerful sword in Blox Fruits.

Common Mistakes and Troubleshooting

Avoid these common CDK hunting errors: Mistake: Not tracking Elite Pirate count. Solution: The game doesn't display a counter. Track your kills manually in notes or a spreadsheet. Mistake: Attempting Tushita puzzle without practice. Solution: Watch multiple video guides beforehand. Know exact torch locations by memory. One mistake means waiting for the next full moon. Mistake: Failing Longma solo. Solution: Bring friends. Longma is soloable but challenging. Having backup prevents wasted full moon attempts. Mistake: Combining swords without max mastery. Solution: It doesn't matter—CDK starts at mastery 0 regardless. You'll grind mastery from scratch on CDK, so there's no advantage to maxing Yama/Tushita first. Mistake: Accidentally selling or storing the swords. Solution: Keep both swords in your primary inventory. Don't store them in chests or accidentally drop them in trades. Mistake: Joining the wrong server type for Elites. Solution: High-population servers have more competition for Elite kills. Consider lower-population servers where you don't have to race other players.

CDK Combos and Usage Tips

After obtaining CDK, maximize its potential with these tips: Basic CDK Combo: Z (stun) → X → C → follow up with fruit/fighting style moves. The Z lands first because it's fast; X follows while they're stunned. CDK + Dough Combo: Dough C → Dough X → CDK Z → CDK X → Dough V → CDK C → Fighting style. This is one of the highest damage combos in the game. CDK + Godhuman: CDK Z → CDK X → Godhuman Z → Godhuman C → CDK C. Fast and efficient for quick kills. Mastery Priority: Focus on Z and X moves first—these are the core of CDK combos. C is useful for mobility but less critical. PvE Usage: CDK's range and damage make grinding faster. The X move hits multiple targets. Use CDK as your primary damage source while Buddha provides tankiness. M1 Combos: CDK has excellent M1 (basic attack) animations. These can be chained into moves for extended combos. Practice the timing for smooth transitions. CDK is versatile—find the combo style that fits your playstyle and practice until it's muscle memory.
