This page is all about the granary on your island sanctuary in FFXIV. Including each expedition, the best expeditions and what materials you should aim for to upgrade your granary, workshops and develop new landmarks.


Granaries On Your Island Sanctuary

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.


Granary Basics

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.

FFXIV Island Sanctuary Granary

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.


How To Upgrade Your Granary

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.

Type Rank Upgrade/Build Time Material 1 Material 2 Material 3 Material 4 Material 5
Base Upgrade 5 2-3 Hours Island Palm Log x10 Island Log x10 Island Clay x10 Island Copper Ore x 10 Island Vine x 5
Granary II 6 6-7 Hours Island Palm Log x15 Island Log x15 Island Hemp x10 Island Clay x5 Island Tin Sand x5
Granary III 8 11-12 Hours Island Log x15 Island Iron Ore x15 Island Leucogranite x10 Island Clay x5 Island Spruce Log x3 (Only obtainable via expeditons)
Granary IV 13 11-12 Hours Island Palm Log x15 Island Coal x15 Island Mythril ore x10 Island Marble x10 Island Spectrine x10

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.


Expedition Areas, Their Rewards and Their Uses

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.

  • Meandering Meadows - Island Alyssum
  • Fatal Falls - Raw Island Garnet
  • Wild Woods - Island Spruce Log
  • Bending Beaches - Island Hammerhead
  • Mossy Mountains - Island Silver Ore
  • Crumbling Caverns - Island Cave Shrimp

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.


What Expeditions Are Best For My Island?

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.
