Learn how to unlock, use, and upgrade the Supply Depot in Fire Emblem Warriors: Three Hopes. Discover how to trade resources for Smithing Stones and essential materials.
The Supply Depot is a facility in Fire Emblem Warriors: Three Hopes that unlocks at the start of Chapter 5. It allows players to trade equipment and resources for Smithing Stones, and then use those Smithing Stones to acquire specific building materials and ores needed for weapon and facility upgrades. It's a crucial way to obtain necessary materials beyond what is found through surveying or battle rewards.
Upgrading the Supply Depot enhances its efficiency, increases the quality and quantity of tradable items, and improves passive resource and ore acquisition during battles. The upgrades require Building Materials (Basic, Quality, Lavish) and Storage Containers (Bags, Chests, Compartments), which are progression-gated and can be found through Surveying Spots or purchased from the Supply Depot itself.
