Island Hideaway Structures

There are three building categories for the Island Sanctuary. They are "Cabin & Fields", "Processing Facilities", and "Landmarks".

Cabin & Fields

Cabins

The hideaway can have one Cabin, unlocked at Sanctuary Rank 1. The Cabin allows players to sell gathered items for those Islander's Cowries () and Seafarer's Cowries (), as well as spending those currencies for attire, hairstyles, minions, mounts, etc.

Upgraded Cabins unlock upgrades for the Pasture and Cropland.

Granaries

The hideaway can have a maximum of 2 Granaries, both of which are available when Granaries unlock at Rank 5.

Upgraded Granaries yield more Rare materials from expeditions.

Landmarks

The hideaway can have a maximum of 5 Landmarks. The first Landmark plot becomes available at Rank 4, second at Rank 5, third at Rank 7, fourth at Rank 9, and fifth at Rank 15.

Each constructed landmark increases the maximum Workshop Groove (to 15/20/25/35/45). Workshop Groove improves the value of Workshop Isleworks Handicrafts.

EXP obtained from initially constructing a landmark on a vacant plot is based on the number of existing landmarks: 1620 (0), 1800 (1), 1995 (2), 2460 (3), and 4550 (4). The EXP values listed in the below table are EXP from replacing a present landmark with the indicated one.

When placing a landmark, players can rotate where it is facing in 90 degree increments.
