Whether you have your eyes set on a particular weapon or you just regret not picking Legic at the beginning of your adventure, the Highly-Concentrated Energy Residue in The First Descendant has your back.
Here’s everything you need to know about where to find Highly-Concentrated Energy Residue in The First Descendant and what it does.
The First Descendant: Highly-Concentrated Energy Residue location
![Anais research development description and menu](https://vip-develop.dotesports.com/wp-content/uploads/2024/07/The-First-Descendant_20240721181124.jpg?w=640)
The best place to search for Highly-Concentrated Energy Residue is inside Hagios. This is the eighth region in The First Descendant and is locked until you complete all regions prior to Hagios. You can either target Hagios missions where the Highly-Concentrated Energy Residue is listed under the Main Rewards (use L2/LT and right analog stick to view the entire list) or search for Encrypted Vaults.
Hagios is hiding 14 Encrypted Vaults, where Highly-Concentrated Energy Residue is a guaranteed drop in at least one. We cannot promise the Energy Residue will always be rewarded on completion due to its low acquisition chance.
While missions are replayable, Encrypted Vaults have a stricter policy. You should alternate between Normal and Hard mode if you’re looking to farm these Vaults. This way the Vault will reset, alongside all possible rewards.
Where to use Highly-Concentrated Energy Residue

Although Highly-Concentrated Energy Residue isn’t a commonly dropped material, it does have its purposes. While it acts as a crafting material, it’s important in the creation of two Descendant Weapons and Lepic (one of the default characters). If you didn’t pick up Lepic at the beginning of the game, then the Highly-Concentrated Energy Residue is a must-have for those looking to unlock this Descendant.
The Highly-Concentrated Energy Residue is part of four recipes. These are:
Research | Research cost | Recipe | What’s it for? |
---|---|---|---|
Restored Relic Nano Tube | 50,000 | 143 Superfluid 125 Monomolecular Eight Extractor Eight Highly-Concentrated Energy Residue One Restored Relic Nano Tube Blueprint | Restored Relic (Weapon) |
Enduring Legacy Synthetic Fiber Blueprint | 50,000 | 102 Ceramic Composite 76 Hellion Eight Highly-Concentrated Energy Residue One Enduring Legacy Synthetic Fiber | Enduring Legacy (Weapon) |
Secret Garden Polymer Syncytium Blueprint | 50,000 | 108 Silicon 76 Hellion Eight Highly-Concentrated Energy Residue One Secret Garden Polymer Syncytium | Secret Garden (Weapon) |
Lepic Enhanced Cells | 200,000 | 290 Semi-permanent Plasma 499 Monomolecular Extractor 34 Highly-Concentrated Energy Residue One Lepic Enhanced Cells Blueprint | Lepic (Descendant) |
Be mindful that completing one of these recipes with your accumulated Highly-Concentrated Energy Residue won’t result in a new weapon and/or Descendant to try. Instead, the Blueprints and Enhanced Cells are just one part of another recipe required to craft the Restored Relic, Enduring Legacy, Secret Garden, or Lepic. This will cost further in-game research time, money, and time spent farming for materials (unless you skip the research process altogether and buy the weapon or Lepic in the Store instead).
