Island Granary

See also: Island Materials

The Granary is a facility added with the Island Sanctuary in Patch 6.2 which allows the player to send mammets to various locations through their island to forage for resources, similar to retainer ventures. Materials obtained from an expedition are yielded every daily reset at 1 a.m. (PDT). Expedition materials include common materials that can be manually gathered on the island, along with rare materials (one per area) that can only be obtained from expeditions. Common materials from expeditions are a good way to keep up with Island Workshop demands and will reduce the amount of manual gathering one needs to do. Rare materials can be used in high-value Isleworks Handicrafts, along with certain facility upgrades.

Players can select one area per granary for an expedition. Each area has several common resources and one rare resource. The yield of each normal resource can range from 0 to 24 (in steps of 2) and is slightly increased with the number of placed Landmarks. Note that in order to obtain a given common resource, players must have previously manually gathered it (i.e., it must be discovered in the gathering log). Rare resources are guaranteed and yield is determined by granary level.

Expeditions cost  50 per real-world day. Up to 7 consecutive days can be assigned at once. Players can freely change the expedition location after it has been assigned. Only materials from the currently active location when the daily reset occurs will be returned.
