Guide to Island Sanctuaries Granary in FFXIV

The Granary is a building that allows you to send mammets to various locations on the island to forage for resources similarly to ventures. These expeditions yield a range of materials, some of which are classed as rare materials. These rare materials can only be obtained through expeditions and therefore should be your key focus.

Expeditions can be sent out for up to seven days costing 50 Seafarer's Cowries every day. The cowries are taken out of your inventory as soon as you decide how many days the expeditions last.

Every day on your daily reset the mammets will return with a collection of normal items and a small amount of rare items that improve as you upgrade the rank of your granary. They do not offer any experience points at all.

While ranking up it is advised to do your Granary one day at a time where possible to save your Seafarer's Cowries. If you can not afford your expedition at the beginning of the day due to upgrading other parts of the island it is not a problem. A single expedition takes up to a day meaning you can send them off 20 minutes before reset and receive the same rewards.

Once you have a comfortable amount of cowries, you can simply send them out for a week at a time. It can be quite convenient to try and set this up so they are ready at the start of each reset so you can collect everything at once.

You can also change what expedition your mammets are out for at any time before the reset for the day if you change your plans.

Up to two Granaries can be built meaning two expeditions at the same time, you can also relocate this building to another plot whenever you would like.

Upgrading your granary offers more materials and therefore gives you more upgrades faster and more Seafarer's Cowries using your workshop. There are 3 upgrades available the first being at rank 6, 8 and 13. These also take time to upgrade but can still be used while being upgraded.

Simply interact with the signboard whenever you want to upgrade. You can change the style of your workshop to any previous upgrade stage whenever you would like. This only offers cosmetic changes.

There are six expedition areas which you can send your mammets to, these do not change and you can send both granaries to the same location if you wish to.

The most important two are having 6x Island Spruce Log for granary upgrades and 9x Raw Island Garnet for workshop upgrades while you progress and grow your island.

From there, 3x Island Silver Ore for the 4th landmark, 5x Island Alyssum for the extra otter-themed landmark and 5x cave shrimp for the Uncharted Course extra landmark.

The most important order for expeditions would be to gain the materials to upgrade your workshops, then granaries and then obtain the silver ore for the final landmark.

After that it simply depends on what supply and popularity your workshop has. Materials with a very high or high popularity should be focused on but aside from that always make sure you have at least 12 of each material but a nice stockpile of at least 20 keeps you comfortable.

At Rank 20, you also have the ability to use these materials to make new Restraints which guarantee the capture of a specific animal. That being said, those are a 1 time use and cost an outstanding 75 Granary materials. I would not recommend these unless you are having a really though time on the rarest animals.
