If you collect resources regularly, you will quickly notice that most materials stop at the 8,000 storage limit. This fills up fast and can hold back your progress. This guide shows how to raise your base storage by unlocking and upgrading a special depot in Arknights Endfield.
Requirement: Stock Bills from Valley Trade
To upgrade your storage, you need Stock Bills. These are earned by managing your outpost and trading goods. Buy elastic goods from the Stock Redistribution Center, then sell them at a friend’s outpost for a higher price. You can do this trade once per day.
Where to Unlock Storage Expansion
Storage upgrades become available after you reach Originium Science Park. Once you complete the main story with Yavon and finish the Research Center section, you unlock access to a device called the Depot Node.
How to Activate the Depot Node
Before using the Depot Node, you need to activate its quest. Open your Quest Log, go to the Important section, then accept and complete Depot Node 1. This unlocks Depot Node 2. After that, you can interact with the Depot Node on the map.
Storage Upgrade Levels and Costs
When you activate the Depot Node, you first need to pay to pull it out of the ground, then upgrade it to Level 1. This first upgrade increases your storage by 3,000, raising the total cap from 8,000 to 11,000.
You can upgrade it again to Level 2, which adds another 3,000 storage and increases the total to 14,000, but this upgrade costs 40,000 Stock Bills. While the cost is high, it is worth it if you farm resources often.
