How to Get the Cursed Dual Katana in Blox Fruits
Learn the requirements, step-by-step puzzle, and upgrade materials for getting the Cursed Dual Katana in Blox Fruits.

TL;DR
To get the Cursed Dual Katana, reach Level 2200 and get both Yama and Tushita to 350 Mastery. Head to Floating Turtle, talk to the Crypt Master, complete six scroll trials to earn Alucard Fragments, then summon and defeat the Cursed Skeleton Boss for a guaranteed drop. You can later upgrade the sword at the Blacksmith using Scrap Metal, Mini Tusks, and Demonic Wisps.
Blox Fruits has no shortage of weapons, but the Cursed Dual Katana stands out as one of the more unique melee options in the game. It comes with its own drawback, though, which puts off a lot of players from even trying to get it.
Getting your hands on this weapon isn't as simple as buying it from a shop or beating a boss. It involves a specific location, a set of requirements, and a bit of patience.
In this article, we'll explore exactly how to get the Cursed Dual Katana in Blox Fruits, along with what makes it worth the effort despite the health drawback.

Requirements to Get the Cursed Dual Katana

Before you even think about starting the puzzle, there are a few boxes you need to check first:
- Level 2200 or higher. This is non-negotiable, and if you show up under that level, the sword won't even let you interact with it properly.
- Own both Yama and Tushita. You can't start the puzzle without having these two swords in your inventory first.
- 350 Mastery on both swords. Owning them isn't enough; mastery only goes up the more you use the sword in combat, so this part takes a fair bit of grinding.
If you're missing either sword, you'll need to get them first. Yama comes from beating Elite Pirates and pulling it from a pedestal on Hydra Island, while Tushita involves defeating the Rip_Indra boss and solving a torch puzzle behind a hidden waterfall door, also on Hydra Island.
Once your level and mastery are sorted, you're ready to move on to the actual Cursed Dual Katana puzzle.

Once your requirements are met, follow these steps to get the Cursed Dual Katana:
- 1. Head to Floating Turtle. Travel to the Floating Turtle island in the Third Sea, and make your way to the back of the Mansion.
- 2. Talk to the Crypt Master. This NPC is found near the back of the Mansion. Speak with him, and he'll open a door leading into the Crypt.
- 3. Enter the Crypt. Go around the corner and step inside. You'll see two scrolls sitting on pedestals on opposite sides of the room: the Tushita Scroll on the left marked by white lanterns, and the Yama Scroll on the right marked by a red lantern.
- 4. Complete the scroll trials. Each scroll gives you three trials, six in total, and you'll need to use the matching sword for each one. It doesn't matter which scroll you start with, as long as you finish all six.
- 5. Collect the Alucard Fragments. Clearing all six trials rewards you with six Alucard Fragments.
- 6. Summon the boss. Place the fragments on the pedestal at the front of the Mansion. This will summon the Cursed Skeleton Boss.
- 7. Defeat the boss. Equip either Yama or Tushita and take him down. The Cursed Dual Katana is a guaranteed drop, so there's no RNG involved here.
If you attempt any of this without meeting the level or mastery requirements, the game will reject you outright, so don't skip that step trying to save time.

Upgrading the Cursed Dual Katana
Once you've got the Cursed Dual Katana in hand, you're not done just yet. Like most swords in Blox Fruits, it can be upgraded through the Blacksmith NPC, and doing so gives it a noticeable boost in power.
To upgrade the CDK, head to the Blacksmith and bring along the following materials:
- 60 Scrap Metal: drops fairly often from regular enemies across the Seas, so this part shouldn't slow you down much.
- 10 Mini Tusks: a bit more specific, so expect to spend some time farming the right enemies for it.
- 10 Demonic Wisps: same deal, tied to certain enemy drops rather than common mobs.
Once you've gathered everything, hand the materials over to the Blacksmith and pay the upgrade cost in Beli. The sword's stat level will increase, which boosts its overall damage output. Keep in mind Scrap Metal has a stack limit of 99 at a time, so it's worth spending what you have at the Blacksmith before farming more; otherwise, any excess gets wasted.
Conclusion
The Cursed Dual Katana is one of those weapons that really tests how far you're willing to grind in Blox Fruits. Between hitting Level 2200, maxing out mastery on two separate swords, and clearing six trials just to summon the final boss, there's no shortcut here. But once it's in your inventory, and especially once it's upgraded at the Blacksmith, you'll understand why so many players consider it worth every hour spent chasing it.
