Overview

The Marine Fortress is a crescent-shaped island northwest of Marine Starter Island that offers quests for players from level 120 to 150.

Appearance

The Marine Fortress is a crescent-shaped island surrounded by stone walls. The upper section of the crescent contains grassy terrain, trees, and various buildings. Four large guard towers are positioned at each corner of the structure. The inner curve of the crescent contains a dock that leads to a tall central building where the Vice Admiral is located. Inside this building, there is an unevenly placed truss. In the frontmost left corner of the fortress, a hidden entrance leads to an area where the Black Cape accessory can be purchased.

Trivia

• Blade fruit is recommended to grind here beacuse of the immunity and long-ranged M1. • If the player chooses the Marines side at the start of the game, they will be teleported right next to the castle. But for Pirates, the player will spawn left or right at the end of the crescent. • It is recommended to use the Marines side to grind the Vice Admiral here because it is closer to the castle. • Like the Military Soldiers at Magma Village, the player can get the Chief Petty Officers stuck near the edge of the stairs and attack them while they are unable to hit the player. • Boats on the Marine Fortress cost cheaper, even if the player is a Pirate.
