Submerged Island is a hidden island located beneath the sea near Tiki Outpost in the Third Sea. It is a late game area tied to advanced progression, and players must first defeat the Tyrant of the Skies before gaining access.

To reach the island, players need to speak with the Submarine Worker, who is located inside Sub Port 01 near Tiki Outpost’s second dock area. This makes access progression-locked rather than openly available through normal exploration.

Visually, the island has a submerged colonial theme with a worn, abandoned atmosphere. Near the entrance is a large gray archway, similar to other old colonial structures. The area is filled with colorful corals, while the center features a massive coral flower surrounded by buildings fused with coral and giant clams, giving the island a distinct underwater appearance.

The left side contains a small abandoned dock scattered with barrels and crates, along with a large coral covered mountain. A small cave at the mountain’s base connects the suspended dock area to the outer dock. Broken archway like ruins can also be seen scattered in the surrounding sea, reinforcing the island’s ancient, sunken feel.

Additional Information:

• Going too high above the island or too far to the sides will return the player to the sea above, resurfacing them at Tiki Outpost.

• The Submarine Worker can be used to return to Tiki Outpost for free or travel to other islands for $10,000–$30,000.

• This island contains the Sealed Cavern, where the Sharkman Master resides.
