Seas and islands
Blox Fruits has three seas only. First Sea runs about levels 1 to 700 with early quests, boats, Aura, and Update 30 Island Secrets. Second Sea unlocks near level 700 after Detective and Ice Admiral, then runs to about 1500 with Fragments, raids, and race V2 or V3. Third Sea opens near level 1500 for endgame grind, Race V4, Mirage, and sea danger events. There is no Fourth Sea in the live game.
Deep links: sea events, quests, bosses.
Sea gates list
First Sea covers levels 1 to 700 for starter quests, boats, early fruits, Aura, and Island Secrets that add Secret levels past about 2800 toward about 3000. Second Sea spans about 700 to 1500 after you finish Detective, beat Ice Admiral, and sail across for Fragments, Café trades, raids, Sea Beasts, and race V2 or V3. Third Sea starts near level 1500 with the story boss chain and holds Race V4, Mirage Island, elite styles, sea danger events, and PvP. Follow the live quest markers for NPC names.
| Name | Band | Detail |
|---|---|---|
| First Sea | Levels 1-700 | Starter quests, boats, early fruits, Aura, and Island Secrets (post-~2800 Secret levels + teleporters after Update 30). |
| Second Sea | Levels 700-1500 | Unlock via Detective → Ice Admiral, then sail. Fragments, Café trades, raids, Sea Beasts, race V2/V3. |
| Third Sea | Levels 1500-~2800+ Secrets | Boss chain near 1500. Endgame grind, Race V4, Mirage Island, elite styles, sea danger events, PvP. Secret levels can push past 2800. |
Danger levels list
Third Sea open water uses Sea Danger Levels that raise event difficulty as the band climbs. Levels 1 through 3 are easier while you learn Sea Beast sailing. Levels 4 through 6 hit harder and reward more risk. Mirage Island can appear while sailing Danger Levels 2 through 6, so mid bands are safer solo if you need to board before an event sinks you. Higher bands also roll Rumbling Waters and tougher Sea Beasts.
- What Danger Levels are. Third Sea open water uses Sea Danger Levels. Higher bands spawn harder events (Sea Beasts, Mirage, Rumbling Waters).
- Farming band. Levels 1-3 are easier while you learn Sea Beast sailing. Levels 4-6 hit harder and reward more risk.
- Mirage hunting. Mirage can appear from Danger Levels 2-6. Mid bands are safer solo so an event does not sink you before you board.
Island Secrets list
Update 30 added about 40 First Sea secrets across puzzles, spawn quests, and awakened Sea 1 bosses. Normal quests stall near level 2800. Secret clears push toward about 3000 (about 5 levels per secret, about 200 total). Finish any one secret to unlock the HUD World Map tracker. Clear all three secrets on an island to unlock that island as a Middle Town teleporter. Secrets are not required before Second Sea at about level 700.
- What they are. Update 30 First Sea secrets: puzzles, spawn quests, and awakened Sea 1 bosses. About 40 secrets total. Each clear pays Secret levels on top of the normal grind cap.
- Level cap. Normal quests stop around level 2800. Secret levels push toward about 3000 once you clear the current First Sea set (about 5 levels per secret, ~200 total).
- World Map and teleporters. Finish any one secret to unlock the HUD World Map tracker. Clear all three secrets on an island to unlock that island as a Middle Town teleporter destination.
- When to do them. Not required for Second Sea. Hit ~700 and cross seas first if you are still unlocking. Come back for Secrets when you want post-cap levels or Sea 1 fast travel.
- Finding them. Use the World Map stars and the Secret Quests table below. Secrets Master in Middle Town hints the next awakened boss. Post-Update-30 First Sea moved puzzle spots, so old coordinates fail.

FAQ
How do I unlock the Second Sea?
Reach about level 700, finish Detective and Ice Admiral, then sail across.
How do I unlock the Third Sea?
Reach about level 1500 and finish the Third Sea story boss chain. Follow the quest markers for the current NPC names.
What are Island Secrets?
First Sea Update 30 content: about 40 secrets (three per island on most islands). Clears pay Secret levels past the ~2800 grind cap toward ~3000, and three-starring an island unlocks its Middle Town teleporter.
How do I level past 2800?
Finish Island Secrets in First Sea. Normal quests stop around 2800; Secret levels are the post-cap path. Unlock the World Map with your first secret, then clear islands for teleporters.
Do I need Island Secrets before Second Sea?
No. Unlock Second Sea the normal way at ~700, then return for Secrets when you want more levels or Sea 1 teleporters.
Is there a Fourth Sea?
Not in the live game. Three seas only. Ignore rumor maps until an official sea gate appears in-experience.
Where is the trade hub?
Second Sea Café. You can still open the official trade window elsewhere.
What are Sea Danger Levels?
Third Sea water difficulty bands. Higher numbers spawn harder sea events.
