First Sea in Blox Fruits: A Full Walkthrough (2026)

Quick answer: Follow the First Sea quest route from your Pirate or Marine starter island, move to the next island as you meet its level requirement, and reach Level 700. To unlock the Second Sea, speak with the Military Detective at Prison, defeat the Ice Admiral in Frozen Village, return to the Detective, then talk to the Experienced Captain in Middle Town. You do not need to complete every Island Secret to make that trip.

The First Sea in Blox Fruits is the beginner region, but the 2026 Sea 1 refresh means older screenshots may no longer match the live island layouts or NPC positions. Use the in-game quest objective and navigation tools as your source of direction. The current official Blox Fruits listing on Roblox advertises the refreshed Sea 1 and a level cap of 3,000; the Sea 2 unlock remains a separate Level 700 quest chain.

How to use this First Sea walkthrough

For a steady beginner route, accept the local quest before fighting and defeat the listed enemies until you qualify for the next quest or island. Quest levels below are practical signposts, not a promise that every player must stop at each location. Some players use boss-focused routes to move faster, but bosses can be contested or difficult; the quest path is easier to follow when you are learning the game.

First Sea island order and level route

Middle Town is a useful First Sea stop for services and travel, but it is not a required grinding band in this route. After the 2026 refresh, some landmarks and boss content changed, so let the live quest NPC tell you which enemy counts for your objective.

First Sea walkthrough, step by step

Step 1: Choose Pirates or Marines and start your first quest

Choose the faction you prefer on the team-selection screen. Pirates and Marines begin on different starter islands and may see different starter NPCs, but both can follow the same broad progression toward Level 700. Find the quest giver, accept the beginner mission, and stay near the starter area until the enemies are easy to defeat. A quest reward adds progress beyond defeating random enemies without an active mission.

Step 2: Follow the island chain instead of guessing

Move to Jungle, Pirate Village, Desert, and Frozen Village as your level and quest options advance. After Frozen Village, continue toward Marine Fortress, Skylands, Prison, Colosseum, Magma Village, Underwater City, Upper Skylands, and Fountain City. Take the local quest each time. If the current island feels punishing, return to the last quest you can complete consistently rather than repeatedly losing fights to stronger enemies.

Step 3: Pick a simple build and spend stats with focus

Decide whether your main damage will come from a Blox Fruit, sword, or fighting style, then focus most damage points on that choice. Keep enough points in Melee for energy and Defense for health so you can use abilities and survive enemy hits. Spreading every point evenly across all damage stats can make the early grind feel slower.

You can use a fruit for its abilities, or build around a sword or fighting style. A fruit is a playstyle choice rather than a requirement for reaching Sea 2. Buy or use what fits your preferred combat, and remember that eating a different fruit replaces your current fruit power. You can also mix weapons and fighting styles around your main damage stat.

Step 4: Clear the midgame islands and keep your loadout practical

From Marine Fortress through Upper Skylands, enemies become tougher and travel takes longer. Keep your best available weapon equipped, use movement abilities to avoid damage, and collect the money from quests for upgrades that help your chosen build. Do not buy every item just because it is available; prioritize useful combat tools and skills. If you are following the standard quest route, the quest giver is usually the simplest way to identify the correct target after an island redesign.

Step 5: Treat bosses as optional boosts, not mandatory checkpoints

Bosses can add a useful challenge and may drop money, experience, or equipment, but they are not always the fastest option. A boss may be on cooldown, another player may be fighting it, or its attacks may outlevel your character. Try the boss when its quest is available and you can survive the encounter; otherwise, keep completing ordinary quests. The 2026 Sea 1 refresh changed some boss names and content, so follow the current in-game boss marker and quest wording instead of assuming a name from an old guide is still current.

Late in the route, continue into Upper Skylands and then Fountain City until you reach Level 700. Keep the local quest active while grinding. If a boss route is crowded or unreliable, the regular quest route gives you a clear next target without waiting for a spawn.

Step 6: Complete the exact Second Sea unlock sequence

1. Reach Level 700. The level requirement alone does not complete the travel quest.
2. Go to Prison and speak with the Military Detective. He gives you the key and sends you to Frozen Village.
3. Open the locked door in the Frozen Village cave. The cave is the one with the Ability Teacher. Use the Detective's key, then defeat the Ice Admiral.
4. Return to Prison and speak with the Military Detective again. Complete the follow-up dialogue after defeating the boss.
5. Travel to Middle Town and talk to the Experienced Captain. After the quest is complete, choose the option to go to the Second Sea.

What changed in the 2026 First Sea update?

The official Roblox listing now promotes refreshed Sea 1 content, and the First Sea has new island layouts and secret objectives. That makes older screenshots and directions to a particular building less dependable. Use the names in the live quest dialogue and the current map or compass where available.

These Island Secrets are separate from the basic Level 700 path to the Second Sea. You can leave Sea 1 after completing the Military Detective sequence without clearing every secret. If your goal is later high-level progression, return to the updated islands and explore their secret objectives; the official game listing currently shows a level cap of 3,000.

Quick tips for a smoother First Sea grind

• Accept a quest before fighting. This gives you a clear target and quest rewards.
• Move on when the next quest is manageable. Staying on weak enemies too long wastes time, while jumping far ahead can turn every fight into a death loop.
• Use bosses selectively. Try them when you are near the right level and the spawn is available; switch back to regular quests if the fight is slow.
• Spend money on your actual build. A useful fighting style, sword, or fruit matters more than collecting gear you will not use.
• Watch for higher-level players. The First Sea is not always empty, so keep an eye out around popular islands.
• Do not confuse the level cap with the Sea 2 gate. You only need Level 700 and the unlock quest to leave the First Sea.

Common problems

The Experienced Captain will not send me to Sea 2

Make sure you are Level 700 or higher, defeated the Ice Admiral after getting the key, and returned to the Military Detective for the follow-up dialogue. Also leave combat before trying to travel.

I cannot find the Ice Admiral

Go to Frozen Village and enter the cave that contains the Ability Teacher. Use the key from the Military Detective on the locked door inside the cave.

The enemies on my island are too strong

Return to the previous island and complete its quest until your damage and health are more comfortable. Check that your stat points support one main damage type and that you have enough Defense and energy for the fight.

My old screenshot points to the wrong place

Sea 1 layouts were refreshed in 2026. Use current NPC names, quest text, and navigation cues; an old screenshot may show a building or route that has moved.

Frequently asked questions

What level do I need to leave the First Sea in Blox Fruits?

You need to be Level 700 or higher and complete the Military Detective quest chain, including defeating the Ice Admiral and speaking with the Experienced Captain.

Do I need to finish all the First Sea secrets first?

No. Island Secrets are optional for the Level 700 trip to the Second Sea. They are part of the newer First Sea progression for players pursuing later levels and rewards.

Can I return to the First Sea after unlocking the Second Sea?

Yes. After unlocking sea travel, use the appropriate travel NPC to move between seas when you need to revisit an island, work on a First Sea objective, or help another player.

For a new player, the simplest plan is to follow the quest chain, keep your build focused, and save the Detective-to-Captain sequence for the moment you reach Level 700. The First Sea is easier to navigate when you treat its islands as a route and use the live game’s updated quest cues.
