Before you start your journey in the Third Sea, make sure you meet these requirements:
Level: Your character must be Level 2200 or higher.
Swords: You must own both Yama and Tushita.
Mastery: Both swords must have at least 350 Mastery.
If you don't have these blades yet, check out our full walkthroughs:
Yama: Defeat 30 Elite Pirates (Elite Hunter NPC) and pull the sword from the pedestal on Hydra Island.
Tushita: Defeat the Rip_Indra boss, find the secret waterfall door on Hydra Island, and light 5 torches within the time limit.
Once you are ready, head to the Floating Turtle island in the Third Sea. Go to the Mansion and look for the secret entrance behind it. Talk to the Crypt Master NPC to unlock the quest room containing two mysterious scrolls.
You must finish three trials for each scroll to proceed.
Dock Legend: Talk to 3 Boat Dealers on different islands.
Duty Done: Successfully complete a Pirate Raid at the Castle on the Sea.
Soulless: Defeat the Cake Queen boss (Ice Cream Land) to enter a special dimension and light the torches.
Pain and Suffering: Let NPCs deal damage to you until the quest triggers.
Haze of Misery: Find and defeat NPCs with purple glowing eyes across all islands while the fog is active.
Fear the Reaper: Summon the Soul Reaper (Haunted Castle) using Hallow Essence and let him defeat you to enter the "Hell" dimension.
Once all trials are done, both scrolls will burn away. Return to the Crypt Master’s room and interact with the pedestal in the center. Prepare for a boss fight against the Cursed Skeleton.
After defeating the boss, you will officially unlock the Cursed Dual Katana.
Farming 350 Mastery for both swords can be a grind. To speed things up, use active Blox Fruits codes for 2x EXP. This will help you reach the requirements for Yama and Tushita twice as fast. Don't forget to keep your light bright!
