While you scour a Sea Fort for treasure, you will come across a locked room on top of it. This locked room is the Fortress Store Room. To open the Fortress Store Room, you’ll need to find the hidden Fortress Store Room key!
How to find the Fortress Storm Room Key
The Fortress Store Room Key is hidden somewhere in an active Sea Fort. However, while the Fortress Store Room Key is guaranteed to be at an active Sea Fort, the key will not spawn at an inactive Sea Fort.
You can specifically find a Fortress Store Room Key inside any of the many pieces of furniture in the fort, such as the cabinets, cupboards, or crates. It can spawn on any floor of the Sea Fort as well.
Don’t forget to check outside! It is also possible to find the key in one of the wooden crates there.
As you search the Sea Fort, you will find Gold Pouches, pieces of treasure, and eventually a Fortress Store Room Key.
Once you have the Fortress Store Room Key in hand, head to the top of the Sea Fort and use it on the door to open the locked room.
Once inside, you’ll find a few extra pieces of treasure and a Firework Crate. You’ve also just added another room to the Sea Fort you’ve just captured!
