Unlocking the Supply Depot in Fire Emblem Three Hopes

When you reach the Base Camp at the start of Chapter 5 you’ll need to talk to your faction leader, who will task you with exploring the new facilities that have opened up. These include the Supply Depot, and since you’re required to visit all the facilities, you really can’t miss this.

The Supply Depot allows you to trade equipment and resources (building materials and ores) for Smithing Stones, and to exchange Smithing Stones for… different building materials and ores. Sounds mundane, but scrapping excess weaponry and unwanted materials so you can get Smithing Stones to either directly upgrade the weapons you kept or to trade for rarer ores required to upgrade high-end weapons. Outside of the resources you obtain from Surveying Spots and the odd story-related gifts, the Supply Depot is the only way to collect building materials, and better yet, you can trade Smithing Stones for the exact building materials you need if you want to finish off a specific upgrade. Likewise, while you’ll gain ores from winning battles, if you need a significant amount of a specific ore (say Umbral Steel or Mythril for upgrading Hero Relics or Sacred Weapons), trading Smithing Stones for them at the Supply Depot is the best option.

The Supply Depot facility is full of excellent upgrades worth unlocking.

Upgrading the Supply Depot in Fire Emblem Three Hopes

By the time you unlock this facility, you’ll have already unlocked the ability to upgrade facilities. Check out the page How to Expand Facilities in Three Hopes for general information about upgrading facilities.

The Supply Depot has the fewest upgrades of any facility, but it’s really a case of quality over quantity in this case. The Supply Depot, as mentioned earlier, allows you to trade Smithing Stones for specific building materials and ores, which is really the only way to accrue extra building materials besides playing through the game again, and is even more vital for obtaining the bulk amount of ore required to fully upgrade high-grade weapons. All of the Supply Depot’s upgrades either increase the efficiency of Smithing Stone trading, hence speeding up the rate at which you can acquire vital resources for upgrading weapons and facilities, increase the quality of items you can trade Smithing Stones for, or cause you to passively obtain more resources, ores and ingredients as you participate in battles. All are worth getting.

Expanding the Supply Depot takes two different types of materials, Building Materials and Storage containers, each of which comes in three tiers (Basic/Bags, Quality/Chests and Lavish/Compartments). These materials are progression gated, so you won’t be finding the mid-tier and high-tier variants until you’ve progressed the main questline. When they do become available, you can regularly find them by exploring Surveying Spots and by buying them from the Supply Depot.

Below you’ll find a list of all the upgrades for the Supply Depot:

Upgrade Prerequisite Resources/Gold Effect

Expand the Supply Line Form a Supply Squad Basic Building Material x10, Storage Bag x10, 1,000 G Slightly increases the types of tradable items.

Supply Squad

Purchasing the “Supply Squad” line of upgrades will cause you to randomly obtain various materials, ores and ingredients as you complete battles… in addition to whatever you were obtaining from the battles themselves. You can stockpile up to three battles’ worth of rewards before you need to talk to the Supply Master and pick the “Collect Supplies” option, otherwise excess battles will just lead to potential resources being lost. The items you gain are random and of variable quality, but you’ll gain around a half-dozen resources each battle once this is fully upgraded, and the quality of resources improves as you advance through the game. This is not a great way to obtain specific resources, but even the junk you get this way can be traded for Smithing Stones, and it functionally amounts to an extra 10+ Smithing Stones per battle. A very useful upgrade which will pay off as you play through the game, it comes highly recommended.

Supply Line

Upgrading the “Supply Line” upgrades will increase the resources you can buy with Smithing Stones, and since the main purpose of the Supply Depot late game is to acquire high-tier ores to upgrade weapons, these upgrades are vital.

Collect Surplus Goods

You trade in junk via the Supply Depot, you gain Smithing Stones, which can then be traded for various materials and ores. The more “Collect Surplus Goods” upgrades you have, the more Smithing Stones you’ll get from trading resources, making the whole process more efficient. A welcome upgrade.

Research Market Prices

Pretty much the same as the “Collect Surplus Goods” upgrade, above, the “Research Market Prices” upgrade makes all those materials and ores you want to exchange Smithing Stones cost fewer Smithing Stones, making the whole process… you guessed it, more efficient. Goes hand-in-hand with the aforementioned “Collect Surplus Goods” upgrades.

(1 of 2) All the Supply Depot upgrades are good, but the Supply Line upgrades will expand the available resources, which is the best way to obtain rare ores.

Which Supply Depot Upgrades to Unlock First?

We’re spoiled for choice when it comes to the Supply Depot, and in the case of this facility, it’s because so many of the upgrades are worth purchasing! While it may not be the most useful upgrade line in the long run, we recommend getting the “Supply Squad” upgrades first, as you’ll gain resources every time you battle, and… battling is kind of the main feature of this game, so you’ll be doing it alot. The sooner you get these, the more materials you’ll collect.

Thes best overall upgrades are the “Supply Line” upgrades, as you really want access to high end building materials and ores, and you can’t buy them from the Supply Master without these upgrades. That said, you really don’t need these upgrades until you can start farming for A-Rank weapons, and as for building materials… well, the Supply Master should be a supplemental source, not your primary source, and until Surveying Spots start dropping high-tier building materials you really don’t have a need for this. While this line of upgrades is useful, it can wait until late game.

Finally comes the “Surplus Goods” and “Research Market Prices” upgrades, which gives you more Smithing Stones when you trade in equipment and resources and reduces the Smithing Stone cost of buying said resources, respectively. It’s going to make getting the Smithing Stones, and hence the building materials and ores, go faster, but obviously you should get the “Supply Squad” upgrades to increase the resources you gain from battles and the “Supply Line” upgrades so you can actually buy high-grade ores, first.
