Fortress Raids[edit | edit source]
While normally dormant, a Fortress will occasionally appear with a large skull cloud hovering above it, visible from a distance.
When this cloud is present, the fortress is active, meaning that a Skeleton horde has gathered there and players can choose to engage in a raid of that Fortress.
Upon arriving at an active Fortress, players can fight their way through waves of Skeletons to the central Fortress structure. Horns signal the arrival of new waves of Skeletons.
After some time, the Fort's Skeleton Captain will spawn. Upon killing him, he will drop a Vault Key, which can be used to unlock a Fortress Vault that contains a large amount of loot. One crew will generally need to make multiple trips to collect it all.
Raiding a Fortress can prove highly difficult, and multiple pirate crews may wish to team up in order to tackle it.
