To reach the Third Sea in Blox Fruits, you must reach Level 1500, complete the Colosseum Quest, defeat Don Swan, help King Red Head fight rip_indra at the Colosseum in the Kingdom of Rose, then talk to Mr. Captain at Green Zone Docks 3 who sails you to Port Town. This guide covers every step in order โ including the Don Swan Fruit requirement and the fastest path through the questline.

Third Sea access requires Level 1500, Colosseum Quest, Don Swan defeat, rip_indra fight with King Red Head, and Mr. Captain's boat from Green Zone Docks 3.
Follow these steps in order โ skipping any step blocks the next.
The hard requirement. You receive an in-game message at Level 1500: "Congratulations on reaching Level 1,500! Ready to go to the next world? Save and talk to the NPC jailed in Colosseum!" Below Level 1500, rip_indra cannot be damaged and King Red Head will not give the quest. Grind Late Second Sea NPCs, Darkbeard raids, and boss quest chains to reach this threshold.
Go to the Cafe in the Kingdom of Rose and talk to Bartilo. He sends you to defeat 50 Swan Pirates behind the large orange building nearby. Return to Bartilo after โ he then sends you to complete a second part of the quest inside the Colosseum. Complete both parts to finish the Colosseum Quest.
Return to Don Swan's Mansion. Talk to Trevor and give him a Devil Fruit worth at least 1,000,000 Beli โ this unlocks the door to Don Swan's room in the right wing. Enter and defeat Don Swan. He uses strong attacks so bring your best gear. Don Swan does not drop notable loot โ defeating him is purely a progression requirement.
After Don Swan is defeated, go back to the Colosseum in Kingdom of Rose. Find the entrance beneath one of the bridges โ head inside into the underground prison room. King Red Head is on the left side. Talk to him, choose "Why admin?" then "Of course admin." He teleports you to a small island to fight rip_indra.
rip_indra is Level 1500 and wields the Dark Blade sword. You must reduce his health to 50% โ a cutscene triggers automatically at the halfway point where King Red Head and rip_indra battle, ending with rip_indra taking King Red Head away. You are then teleported back to the Mansion in the Kingdom of Rose. Note: rip_indra is immune to damage without a team if below 50% health, so stop attacking at 50% and let the cutscene play.
After the cutscene, a "Read" button appears on screen โ click it. Then go to the Green Zone docks (also called Docks 3) in the Second Sea. Find Mr. Captain NPC standing at the edge of the dock near the front of the island. Interact with him and select "Yes" when he asks if you want to sail to the Third Sea.
Mr. Captain teleports you directly to Port Town, the starting area of the Third Sea. This is your base of operations for all Third Sea progression. You now have access to Level 1,500โ2,550 content, Race Awakenings, Elite Pirates, Sea Danger Levels, and new fighting styles like Electric Claw and Godhuman.
Level 1500 boss with Dark Blade โ harder than most Second Sea bosses.
rip_indra uses the Dark Blade with its full moveset including ranged dark slash waves and close-range combo attacks. He can deal high damage per hit. Keep Observation Haki active at all times โ his attacks are fast enough to land before you can react without Instinct evasion.
Fight in a group of 2โ3 players for the safest and fastest route to 50% health. Awakened Buddha or high-range fruits (Magma, Light, Venom) allow you to maintain distance. Stay mobile and avoid his dark slash waves which travel in a straight line โ sidestep rather than retreating.
Everything that becomes available once you arrive at Port Town.
Third Sea is approximately 3x larger than Second Sea. New islands include Floating Turtle, Haunted Castle, Ice Cream Land (Sea of Treats), Tiki Outpost, and more. Fast travel via portals unlocks later โ early Third Sea requires sailing between islands.
Third Sea covers Level 1,500 to max 2,550. The jump in NPC difficulty is significant โ most enemies have Aura making Logia immunity less effective. Expect a much harder grind per level than Second Sea, especially above Level 2,000.
Electric Claw fighting style (Previous Hero), Godhuman prerequisites, Sanguine Art (Leviathan Heart), Race V4 awakenings, Instinct V2, Cursed Dual Katana sword, Soul Guitar, Elite Pirates and God's Chalice system, Sea Danger Levels (0โ6).
Before entering Third Sea: upgrade your fighting style to Electric Claw or Godhuman direction, save 5,000+ Fragments, have at least 1,500+ Mastery on your main style, and bring strong accessories. Third Sea NPCs hit significantly harder than anything in Second Sea.
For the Third Sea fighting style upgrades available immediately after arriving, see our CDK guide. For the trading values of fruits farmed in Third Sea content, see our Blox Fruits trading values guide.
Most players get stuck at one of these points โ know them before you start.
The most common mistake. If you deal too much damage and push rip_indra below 50% health, a dark cloud surrounds him and he regenerates. You cannot kill him and the cutscene triggers at exactly 50%. Stop attacking when his HP bar reaches the halfway mark and wait for the cutscene.
King Red Head will not give the rip_indra fight option until the full Colosseum Quest is completed. Players who skip Bartilo's quest and go straight to King Red Head are turned away. Complete both Bartilo quest parts first before approaching King Red Head.
King Red Head is underground beneath the Colosseum โ not on the main floor. Find the entrance under one of the bridges leading to the Colosseum building. Without knowing the underground entrance, players wander the Colosseum floor indefinitely without finding him.
Trevor requires a Devil Fruit worth at least 1,000,000 Beli. Common or Uncommon fruits will be rejected. Bring a Rare or higher fruit worth the minimum. You lose the fruit permanently โ budget a sacrificial fruit in advance rather than giving away something valuable.
