Exclusive to: Shipwrecked.
Ballphin Palaces are naturally spawning Structures introduced in the Shipwrecked DLC. They are found on the Ocean in Coral Reefs, and spawn Bottlenose Ballphins. They can also be crafted using 4 Limestones, 4 Seaweeds and 2 Dorsal Fins, are found in the Structures Tab, and require a Science Machine to prototype.
Each Ballphin Palace spawns a Bottlenose Ballphin every 4 days that returns there at Dusk. However, a Ballphin Palace can hold more than the Bottlenose Ballphin that it spawns; if other Ballphins are nearby when Dusk begins, they may choose to go inside a Palace that they did not spawn from.
As with most craftable structures, Ballphin Palaces (including naturally occurring ones) can be Hammered to return half of the resources needed to craft it.
- Unlike with Pig Houses, the lights of a Ballphin Palace will not go off when the player gets too close. This allows them to be used as a rather cheap nighttime light source, if the player's boat has enough durability to last a night at sea.
- Bottlenose Ballphins do not react to the player destroying their palace, so these can be a decent source of Limestone if the player cannot find any Coral Reefs.
- Ballphin Palaces were added to the Shipwrecked DLC more than a year after its official completion in the Home Sea Home update, after being tested in a beta branch for several months.
