Discover the secrets of the optional Ghost Ship in Rogue Company. Find valuable treasures like the Thunder Shield, learn enemy weaknesses, and navigate its challenging layout.
After completing the game, you can explore the optional Ghost Ship area. Load your save file (marked with a silver star), and your party will be at Mother's Lair. Teleport to the Dorgenark: Control Room, use the helm to access the Galaxy Map, and select the new Ghost Ship destination. Upon arrival, a scene will play. Afterward, collect the Thunder Shield outside the ship before entering through the large north door.
Arabis's Ghost Ship is a sprawling, multi-level dungeon filled with numerous items. Its rooms are generally small, often featuring two levels, which can complicate battles by allowing enemies or players to change elevation unexpectedly. Be prepared for enemy shields, barriers, and jump attacks.

Navigate the entrance hallway into the first room, which has upper levels on either side. The east upper level contains a chest with Perfect Elixir x2. In the next room to the north, a chest near the west wall holds a Dark Onyx. In the large room to the north, a chest behind a short rail in the southeast corner contains a Brave Symbol.
Upon exiting the large room, you'll encounter Arabis's butler, Sebastian. After the scene, proceed east. Use the Sun Key to unlock the chest near the south wall of the next room, yielding a Galactic Compass. Two more chests are on an upper level in the northeast corner; the left one contains Relaxing Aroma x5, while the right one requires disarming a Cursed Trap to obtain the Dark Music Box.
Continue east through the next room and then south through two more. In the subsequent room, ascend the west side to enter the room to the west. Proceed through these rooms until you reach a dead end to the north. A platform juts into this room, holding two chests: one with a Rose of Passion and another with a Forbidden Add-On.
Return south and east to the room you climbed out of. Go south again and open a chest on the west side for a Chameleon Particulate. Proceed east and through the door ahead. Climb up and go north, passing through three rooms, to another room with a jutting platform. The chest on the west side contains a Brave Symbol. Jump up on the south side of the next room and enter the room to its south. A chest atop the jutting platform holds Recharge Drink x5. The room to the east has two upper levels flanking the central path. Ascend the east upper level to find a chest with Attack Seal x2. Then, enter the long room to the south. Across a gap is a platform with three chests: the left is a Mimic, the center requires disarming a Bomb Trap to yield a Hyper-Gravity Sensor, and the right contains a Queen Bee Stinger. On the lower level of this room, two more chests are against the north wall; the left is another Mimic, and the other contains Dreamflower Ash x2.
Exit the long room via the south door and proceed as far south as possible. In the southwest corner of the next room to the west, find a chest with Perfect Heal x3. Return to the long room and head north. In the room beyond, navigate around a jutting platform. A treasure chest on the north upper level of the room to the east contains a Guardian Sphere.
Proceed through the door to the east and save your game at the transporter outside the Ruined Hall. Inside, a scene will initiate, appearing as a boss battle. During this scene, a Mysterious Young Man defeats the enemy and departs with a warning. Ascend the stairs on the south side of the hall and exit east.
In the long room east of the Ruined Hall, near the northeast exit, is a chest containing an Ultraspicy Pepper. Leave this room via the southeast exit.
