The Submerged Island is one of the most exciting additions in Blox Fruits to date. It challenges players to prove their strength while rewarding them with powerful upgrades, rare loot, and new quests.

The Prerequisites: Unlocking the Third Sea

Before setting your sights on Submerged Island, you’ll need access to the Third Sea. That means:

  • Level 1500 minimum
  • Completing the required quests to unlock the Third Sea

If you’re not there yet, your first goal should be hitting that milestone. Submerged Island is endgame content designed for seasoned players.

The Key Location: Tiki Outpost

Once you’re in the Third Sea, head over to Tiki Outpost. This is the last island before you dive beneath the waves. Hidden within its bustling hub is the NPC who can help you reach the Submerged Island.

The Submarine Worker & The Tyrant of the Skies

Step 1: Find the Submarine Worker

  • Go to SUB PORT 01, located on the backside of Tiki Outpost.
  • Look for the Submarine Worker NPC near the Sun-kissed Warriors.

Step 2: Prove Your Strength

The Submarine Worker won’t just take you for free—you must defeat the Tyrant of the Skies first.

Step 3: Defeat the Tyrant of the Skies

  • This boss is no pushover, so bring your strongest Devil Fruit, best fighting style, and a solid sword.
  • Once you defeat him, you’ll have proven yourself worthy.

Step 4: Board the Submarine

  • Return to the Submarine Worker.
  • Interact and select “Yes” twice.
  • The submarine will teleport you straight to the Submerged Island.

What Awaits You on Submerged Island

The grind to get there pays off—Submerged Island is full of fresh content:

  • New Quests: Tons of NPCs with XP-rich questlines to help you level up fast.
  • Lightning Ability Upgrades: This island is the key to powering up your lightning skills from the new update.
  • Exclusive Materials: Collect rare event materials for crafting and upgrades.
