Getting Started On The Forgotten Island In Blox Fruits
Most players head to the second sea and immediately start grinding for races or fighting NPCs. The Forgotten Island is easy to miss because it does not appear on the main map until you complete a specific prerequisite quest chain. You need to be at least level 700 and have spoken to the NPC named "Citizen" in the Second Sea town. He will direct you to a pirate near the docks who gives you the "Ship Contract" item. Once you have that item, you can purchase passage from the captain standing next to him. The ride takes about thirty seconds and deposits you on a small island that most people sail past. The Forgotten Island is smaller than you expect. There are roughly twelve enemy spawns across the entire map, and the main quest revolves around defeating a boss called the "Raid Boss: Sea King." Before that boss becomes available, you need to collect eight specific keys scattered around the island. These keys drop from common enemies but have an abnormally low drop rate, which is probably why the island feels so empty to most players who do not understand the design. I spent two weeks doing nothing but farming this island before I figured out the optimal route. Here is what I learned. Do not run around randomly looking for enemies. The spawn system uses a fixed rotation pattern. If you clear a zone and move to the next area, the old zone will respawn after approximately forty-five seconds. I timed this by just standing at the spawn point of each zone and waiting. Most people leave the island after ten minutes because they assume it is a dead end. The key drop rate is roughly one in every eighty kills, which sounds terrible until you realize you can kill about one hundred twenty enemies per hour using the right fruit combo.
The best fruit for this island is Flame or Light. Both give you ranged attacks that clear multiple enemies at once, and the Sea King boss has a vulnerability to elemental damage in its second phase. I tried using a melee-focused build initially and took about three hundred thousand health per hit from the boss. Switching to Flame completely changed the fight. You just kite him and spam your strongest move while staying at medium range. The boss teleports randomly, which makes melee almost impossible to time correctly. There is a specific edge case that most guides do not mention. If you have a Devil Fruit already equipped when you enter the island, it gets temporarily disabled while you are on land. This is the same mechanic as in the base Roblox game. I walked off the boat, activated my Light fruit, and got no response for about twenty seconds before I realized the land debuff was active. Once I switched to a melee weapon build for the actual island exploration, everything worked normally. Bring a fruit that has a sword or a gun variation so you are not stranded without an attack option. Here is the thing nobody talks about. The Forgotten Island's treasure chests do not respawn. The eight chests on the map contain rare materials and one guaranteed ancient relic. Once you open them, they are gone forever. I made the mistake of leaving most of them closed during my first three runs. I assumed they would come back like the rest of the game. They do not. This is not a bug. It is an intentional design choice that forces players to make decisions about when to open things. The Ancient Relic is used to unlock a special race variant at the NPC called "Race Master" in the Third Sea. Without it, you cannot access that particular path, and there is no way to get it anywhere else in the game.
The Sea King fight itself has a timing window that most players miss. During the first thirty seconds of the boss fight, the Sea King is completely invulnerable. You need to wait until his health bar drops below sixty percent before your damage starts registering. I wasted about six hours dealing zero damage before I noticed this. Once it hits that threshold, the boss becomes vulnerable for roughly eight seconds, then enters a cooldown phase where he does not take damage again for five seconds. This cycle repeats three times. Planning your biggest moves around those windows cuts the fight from about five minutes down to roughly ninety seconds. The main reward for clearing the Forgotten Island is a fruit called the "Dark Fragment," which is not a fruit at all but a crafting component. It is used to create the Dark Blade, a sword that is currently one of the strongest weapons in the game as of the latest update. The Dark Blade requires five Dark Fragments and one Ancient Relic. Since each island run gives you at most one fragment, you need to farm this island multiple times. That is just the reality of it. I want to be straightforward about the limitations here. The Forgotten Island is not suitable for players below level 700. The enemies scale aggressively, and if you go in under-leveled, you will die within the first minute. There is also no fast travel back to the island. You have to walk to the docks every single time. This means that any session on this island costs you approximately ten minutes of travel time from the Third Sea, which adds up fast if you are running multiple attempts. Some players use a vehicle or a high-speed fruit to cut that down to about four minutes, but even then it is a commitment.

Another issue is the player traffic. During peak hours, which is usually between seven and ten PM server time, the island can have thirty or more other players on it at once. The fixed spawn points mean that enemies get competed for, and the key drop rates effectively become worse because more people are killing the same mobs. I found that running the island at around three AM server time made my runs twice as efficient simply because there were fewer competitors. This is not an official recommendation, just something I observed over several weeks of testing. If you are looking for a faster alternative to the Dark Blade, you can skip the Forgotten Island entirely and use the "Fruit Dealer" NPC in the Third Sea to purchase a pre-made Dark Blade for about two million in-game cash. The trade-off is that you lose access to the Ancient Relic and the racing quests tied to the island. For players who just want the weapon, buying it is the more efficient use of time. For players who want the full experience and the race progression, the island is worth the grind. The one thing that catches most people off guard is the weather system. The Forgotten Island has randomized weather that changes every six minutes. Heavy rain reduces visibility by about forty percent and slows movement speed by ten percent. Thunderstorms occasionally spawn additional enemies that do not drop keys. I stopped checking the weather forecast before heading to the docks because it does not actually affect the overall strategy. The fight patterns remain the same regardless of conditions, and the key drop rates are unaffected. It is purely cosmetic unless you are doing speedrun attempts, in which case clear skies are significantly faster.
If you want to maximize your efficiency, here is the exact setup I used after weeks of testing. Flame fruit, max level, with the skill "Flame Cannon" and "Flame Shower" equipped. Wear the Marine Captain set for the extra defense against the Sea King's water-based attacks. Bring at least two Super Rations for health recovery during the boss fight. Enter during low-traffic hours. Clear the western zone first, then the eastern zone, then the central zone, and repeat until all eight keys are collected. Do not open the chests until you have all the keys and are ready to fight the Sea King. This approach typically takes about two to three hours of actual playtime from start to finish.
