The resource, Reverse Charging Coil, has many uses in The First Descendant. They are a much-needed material to stockpile, even if you don’t plan on researching Descendants or Ultimate Weapons. Here’s how to get Reverse Charging Coils and every recipe it is used for in The First Descendant.
Where to Get Reverse Charging Coils in The First Descendant
If you are farming Reverse Charging Coils, you need to unlock the last region on normal mode, the Fortress. These materials drop from Resource Boxes and Munition Capsules, similar to farming common materials like Ceramic Composites. Finding these Munition Capsules and Resource Boxes is quite random, but they actually have fixed spawn points. They also respawn relatively quickly (less than 2 minutes).
