Your boat docks. The sky shifts to a darker blue, the air feels thicker, and suddenly the map in your menu looks like someone unfolded a second page. That is the moment every Blox Fruits player remembers – stepping into the Second Sea for the first time. Everything you grinded in the First Sea is still with you, but the rules have changed. The mobs hit harder, the quests demand more, and the islands stretch out in an order that punishes anyone who guesses wrong.
This guide walks you through every step of Second Sea progression. You will learn how to unlock it, which islands to tackle in order, where the key bosses spawn, and the mistakes that slow most players down by hours.
How to Unlock the Second Sea
The gate to the Second Sea is not automatic. At level 700, go to the Prison in the First Sea and find the Military Detective. He gives you a quest to defeat the Ice Admiral, a boss who sits in the frozen prison wing. The fight is not hard if you are actually level 700 with a decent fruit, but players who boosted their way up or skipped farming will struggle.
After you beat the Ice Admiral, talk to the Military Detective again. He directs you to a special NPC who teleports you to the Second Sea. Once you arrive, you land at the Kingdom of Rose – your new home base for a long stretch of levels.
Key point: You cannot return to the First Sea easily after this transition. Finish any loose quests, stock up on Beli, and make sure your current fruit and fighting style are where you want them.
Second Sea Overview: What Actually Changes
The Second Sea covers levels 700 to 1,500. That is more than double the level range of the entire First Sea, so the pacing feels different. Quests give more XP but require more kills per stage. Bosses respawn on longer timers. New systems unlock – most notably, the Awakening feature for fruits, which you will want to start thinking about around level 1,000.
Enemies also gain new attack patterns. The swan pirates in the Kingdom of Rose are the gentle introduction, but by the time you reach the Haunted Castle or Ice Castle, you will face mobs with knockback, stuns, and ranged combos. The First Sea taught you to button-mash. The Second Sea punishes that.
Every Second Sea Island in Order
The Second Sea has a mostly linear island chain. Skipping ahead without the levels to match makes quests impossible and farming painfully slow.
| Island | Level Range | Key Boss | Notable Feature |
|---|---|---|---|
| Kingdom of Rose | 700-850 | Diamond | Main social hub, quest givers |
| Green Zone | 875-950 | Fajita | Spinny fruit NPC, grinding spot |
| Graveyard Island | 950-1,000 | Cursed Captain | Underwater City quest trigger |
| Snow Mountain | 1,000-1,100 | Yeti | Jeremy quest, Yeti drop |
| Hot and Cold | 1,100-1,200 | Smoke Admiral | Science weapons unlock |
| Cursed Ship | 1,100-1,200 | Cursed Captain (night) | Elite Pirate farming |
| Ice Castle | 1,200-1,300 | Awakened Ice Admiral | Endgame grind zone |
| Forgotten Island | 1,300-1,425 | Tide Keeper | Long-arm tribe quest chain |
| Haunted Castle | 1,425-1,500 | No boss | Final stretch before Third Sea |
Kingdom of Rose (700-850)
This is your landing zone. The town is large, NPCs are clustered, and the swan pirates outside the gates give solid XP for the early 700s. The Diamond boss spawns near the fountain in the central area. He drops the Longsword, a decent early Second Sea weapon if you are still running a starter blade.
Do not rush off this island too fast. The density of quests and the relatively gentle mobs make it the best place to adjust to Second Sea combat pacing.
Green Zone (875-950)
The Green Zone is a jungle island with fewer NPCs but higher-level mobs. Fajita spawns here as a boss, and the Master of Auras NPC lives in a hidden hut. This is your first chance to unlock aura upgrades, which you should grab immediately. Aura makes a noticeable difference against the tankier mobs from this point forward.
Graveyard Island (950-1,000)
Small, gloomy, and easy to miss if you are not watching the map. The Cursed Captain spawns here at night, and he is required for a quest chain that eventually leads to the Underwater City. The mobs are skeletons and zombie pirates. Their attack patterns are slow but hit hard, so keep moving.
Snow Mountain (1,000-1,100)
The Yeti is the headline boss here, but the real draw is the Jeremy quest. Jeremy is an elite NPC who gives a fighting style quest reward. The snow troopers on this island have wide AoE attacks, so clustering them for farming is riskier than it looks. Pull smaller groups until you are comfortable.
Hot and Cold (1,100-1,200)
This dual-biome island has both lava and ice zones. The Smoke Admiral boss lives in the hot zone, and the science weapon vendor is tucked into a lab building. If you want the Superhuman fighting style later, you need to start buying and upgrading science weapons here. The temperature effect is purely visual – it does not damage you.
Cursed Ship (1,100-1,200)
A night-only raid-style area. The Cursed Captain appears here as well, but the real value is Elite Pirate farming. Elites drop Fragments, the currency you need for fruit awakenings and special purchases. Start farming Fragments here even if you are not ready to awaken yet. You will need thousands later.
Ice Castle (1,200-1,300)
The Awakened Ice Admiral returns as the boss here, and the mobs are some of the toughest in the Second Sea. This island is a pure grind zone. Most players park here for several levels because the quest density is high and the layout is compact. The cold theme is fitting because you will be here long enough to feel it.
Forgotten Island (1,300-1,425)
A tribal-themed island with the Tide Keeper boss. This is where the Long Arm Tribe quest chain finishes, rewarding you with access to a unique fighting style if you followed the chain from Snow Mountain. The mobs here have fast melee combos. If you are running a ranged fruit like Light or Flame, this island is easier than it looks.
Haunted Castle (1,425-1,500)
The final Second Sea island. There is no major boss, but the quests bridge you into Third Sea territory. Most players do not linger here because once you hit 1,500, the Third Sea opens and the XP gains there outpace anything in the Second Sea.
What Players Get Wrong in Second Sea
Rushing to new islands under-leveled is the single biggest mistake. A level 720 player who sprints to the Green Zone will spend twice as long per quest as a level 780 player who stayed in the Kingdom of Rose. The level scaling on quests is strict. If you are below the recommended range, kill times balloon and death frequency rises.
Another common error is ignoring Fragments early. Players see the Cursed Ship as optional because it is dark and annoying to navigate. Then they hit level 1,200, decide they want to awaken their Buddha fruit, and realize they need 5,000+ Fragments with no stockpile. Farm the Cursed Ship during your natural level range so the Fragment grind does not become a separate chore later.
Wasting time on low-XP mobs is a quieter mistake. Some players clear every mob on an island out of habit from the First Sea. In the Second Sea, quest turn-ins give the bulk of your XP. Killing extra mobs between quests is inefficient unless you are specifically farming drops.
Finally, do not skip aura upgrades. The Master of Auras NPC in the Green Zone sells upgrades that increase your damage against aura-using enemies. Most Second Sea mobs fall into that category. The upgrade is not flashy, but the DPS increase is consistent across every fight.
Optimal Progression Order
Here is the cleanest path through the Second Sea:
Land at Kingdom of Rose and stay until 825+. Complete every quest, kill Diamond when he spawns, and get comfortable with the faster mob attacks.
Move to Green Zone at 875. Buy your first aura upgrade immediately. Farm until 950.
Graveyard Island from 950 to 1,000. Do the Cursed Captain quest at night. This unlocks the Underwater City entrance later.
Snow Mountain to 1,050, then finish the Jeremy quest. Do not leave without the fighting style reward.
Hot and Cold from 1,100 to 1,150. Buy at least one science weapon. Even if you do not use it, it counts toward the Superhuman unlock later.
Cursed Ship at night from 1,100 onward. Stack Fragments even if you do not need them yet. Elite Pirates give good XP too.
Ice Castle from 1,200 to 1,325. This is your longest grind. The layout is efficient and the quest NPC is close to the mob spawns.
Forgotten Island from 1,300 to 1,400. Finish the Long Arm quest if you started it.
Haunted Castle from 1,400 to 1,500, then transition to Third Sea immediately.
Counter-Intuitive Tips That Save Hours
Stay in First Sea to max your fruit first. If your current fruit is close to its full mastery – within 50 levels – finish it in the First Sea before crossing over. Second Sea mobs are tankier, which means slower kills, which means slower mastery gains. A fully mastered fruit entering the Second Sea makes the 700-850 transition far smoother than rushing in at 700 with half mastery.
Do not awaken your fruit the moment you can. Awakening costs Fragments, and early Second Sea players are usually Fragments-poor. Unless your fruit is Buddha – which pays for itself immediately – consider waiting until you have a comfortable buffer of 8,000+ Fragments. Being broke in the Second Sea means you cannot buy boat repairs, aura upgrades, or emergency items.
Skip the Underwater City initially. It unlocks after the Graveyard quest, but the level range overlaps with better farming zones above ground. Come back later when you are over-leveled and want the specific drops.
Buddy up for the Cursed Ship. Solo navigation at night is disorienting. Even one friend who knows the layout cuts your Elite kill time in half because you can split the mob search.
Buddha is boring but correct. Everyone wants to run the flashy new fruit they picked up. If your goal is efficient progression, Buddha’s transformed state with melee click damage out-grinds every other fruit in the Second Sea. Save the fun fruits for PvP after you hit 1,500.
FAQ
What level do I need to enter the Second Sea in Blox Fruits?
You need to be level 700+ to enter the Second Sea. Talk to the Military Detective at the Prison in the First Sea to start the quest that unlocks access.
Is Second Sea harder than First Sea?
Yes, enemies scale from level 700 to 1,500. The difficulty jump is significant if you rush in at exactly level 700 with poor gear. Farm the first few islands carefully before pushing deeper.
What’s the best fruit for Second Sea progression?
Buddha is the consensus best for leveling through Second Sea due to its massive AoE and damage reduction. Magma and Light are also strong alternatives if you prefer ranged combat.
