The First Sea in Blox Fruits is where every adventure begins, and this full walkthrough takes you from a level-zero rookie on the spawn island all the way to Level 700 and your departure for the Second Sea. The First Sea (often called Sea 1 or the Blue Sea) is a long string of islands tuned to specific level ranges, so the smart approach is to move through them in order, finishing quests as you go.
This guide keeps things practical. You will see exactly which islands to visit, when to grab your first Blox Fruit, sword, and fighting style, and what it takes to unlock the journey to the next sea. Follow the steps below and you will never wonder where to go next.
What you need before you start
- A fresh or low-level character in the First Sea (this is the default starting sea).
- Money and fragments earned from quests and bosses for gear and upgrades.
- A plan for your build — sword, gun, or fruit main — so you know what to spend on.
- Patience for grinding: the First Sea takes you through roughly 700 levels of content.
First Sea walkthrough, step by step
-
Step 1: Start on the spawn island and pick a side
You begin at the starter island, where you choose to side with the Pirates or the Marines. The choice mainly affects flavour, some NPCs, and a few quests, so pick whichever appeals to you. Find the quest giver, accept the bandit quest, and start defeating low-level enemies to earn your first experience. These early kills carry you smoothly through the opening levels.
Pick Pirate or Marine, then take the first quest to grind bandits. -
Step 2: Follow the island chain in level order
The First Sea is built as a progression path. After the spawn area you move through islands such as the Jungle, Pirate Village, Desert, and Frozen Village, each tuned to a higher level band. Every island has a quest NPC who points you at the right enemies, so always take the local quest before grinding. Beat the enemies that match your level, then sail to the next island rather than skipping ahead into mobs that are too strong.
Hop island to island in order, matching each location to your current level. -
Step 3: Get a Blox Fruit, sword and fighting style
Early on, visit the Blox Fruit Dealer to buy or use a fruit — you can eat one for its powers or store it to sell or trade later. Pick up a starter sword from a sword dealer or as a drop, and learn a fighting style from an NPC trainer. A fruit changes how you fight and is a bigger commitment, while swords, guns, and fighting styles work with almost any build, so it is worth deciding your direction early.

Step 4: Grind the mid-game islands to Level 450
The middle stretch of the First Sea takes you to floating and themed islands like the Skylands, Magma Village, the Underwater City, and Fountain City. Enemies hit harder here and quests give better rewards. This is a great time to bank fragments and money so you can upgrade your weapons or save toward a stronger fruit. Keep clearing quests in order and your level will climb steadily toward 450.
The mid-game islands carry you from Level 120 up toward 450. -
Step 5: Beat key bosses and reach Level 700
The final stretch is about the high-level islands and the tough enemies and bosses they contain. Bosses drop generous experience, money, and sometimes rare gear or titles, so they are worth hunting. Keep upgrading your build, clear the remaining quests, and push your level toward 700. That number matters: 700 is the requirement to leave the First Sea, so treat it as your finish line for this sea.
Clear high-level islands, farm bosses, and push your level past 700. -
Step 6: Talk to the NPC to sail to the Second Sea
Once you hit the required level, head to the relevant Pirate or Marine base and find the NPC who handles the journey to the next sea (often located on an upper floor of the base). Talk to them, confirm, and you will set sail for the Second Sea, leaving the First Sea behind. From there a whole new map, story quests, and stronger fruits await.
Find the base NPC, confirm, and sail off to begin the Second Sea.
Tips for a faster First Sea
- Always take the local quest. Quests guide you to the correct enemies for your level and reward bonus experience and money.
- Do not over-level on weak mobs. Move on once enemies stop giving good experience and find the next island in the chain.
- Save fragments and cash. A timely weapon upgrade or a better fruit makes the later grind much quicker.
- Use bosses for big jumps. Boss fights are some of the most efficient experience in the sea once you can survive them.
- Group up. Teaming with friends speeds up boss runs and the longer grinding stretches.
Troubleshooting
Enemies feel impossible to beat
You have probably moved to an island above your level. Sail back to an easier island, finish its quest, and level up before returning. Upgrading your sword or fighting style helps too.
I cannot leave the First Sea
Departure is level-gated, so make sure you have reached the required level (around 700) before talking to the travel NPC at the base. If the option still does not appear, double-check you are speaking to the correct NPC for sea travel.
I do not know which island is next
Open your quest log and follow the suggested objective, or simply look for the island tuned to a level just above your current one. Progress in the First Sea is almost always linear.
Frequently asked questions
What level do you need to leave the First Sea in Blox Fruits?
You need to reach roughly Level 700 to unlock the journey to the Second Sea. Once you hit that level, talk to the travel NPC at your faction's base to set sail.
Does it matter whether I pick Pirate or Marine?
Not much for the core walkthrough. The choice changes some NPCs, a few quests, and the flavour of your run, but both factions progress through the same island chain.
Should I eat my first Blox Fruit or sell it?
It depends on your build. If you want fruit-based powers, eat one that suits your playstyle. If you are going for a sword or gun build, you can store and sell fruits to fund upgrades instead.
How long does the First Sea take?
It varies with playtime and whether you team up, but expect a meaningful grind since the First Sea spans roughly 700 levels of quests and bosses.
Can I come back to the First Sea later?
Yes. You can travel between seas, so revisiting the First Sea to trade, farm specific items, or help lower-level friends is always possible.
Final thoughts
The First Sea in Blox Fruits is your training ground: pick a faction, follow the island chain in order, gear up with a fruit, sword, and fighting style, then grind bosses until you reach the level needed to move on. Stick to the level-appropriate islands, keep your equipment current, and the climb to Level 700 will feel steady rather than overwhelming. When you are ready, the official Blox Fruits page on Roblox is the place to jump back in and start your voyage to the Second Sea.
