This article details how to fast and efficiently obtain all the materials needed to make Arche Crystals, making your Descendant more powerful.
Murky Energy Residue 
Focus on completing the Unknown Laboratory quest in Sterile Lands. Opt to solo or team up with friends. Avoid public matchmaking if you plan on repeating the mission quickly to ensure you don't disrupt other players’ gameplay.
Normal Mode: Suitable if you're not fully kitted out or prefer a less challenging experience. Rewards are decent but lower compared to Hard mode.
Hard Mode: Recommended if you're well-equipped. Offers higher rewards and more Murky Energy Residue per run.
Tips
1. The mission's goal is to quickly reach and kill Vulgus Panzer. It is recommended to use Bunny, which can kill other enemies on the road while running, reducing unnecessary battles to save time, This requires a sufficiently powerful AOE.
2. Vulgus Panzer drops the Murky Energy Residue upon defeat. Expect about 9 on Normal and up to 15 or more on Hard mode.
3. After collecting the drop, reset the mission to start over without having to leave the area. This can be done through the game’s mission reset feature or by exiting and re-entering the mission area.
4. Continue this process as often as necessary to gather your desired amount of Murky Energy Residue. Speed is key to maximizing your efficiency.
In addition to the Unknown Laboratory missions, you can double up and just do the Forgottense mission. You get Murky Energy Residue from the elite in the middle of the mission and the 009 amorphous from completion, which opens 15% of the time to the catalyst blueprint.
Macromolecule Biogel 
The drop rate of Macromolecule Biogel has increased after the game was updated. It is recommended to go to Muskeg Swamp: Vulgus Strategic Outpost, run directly in, shoot the activators spawn the boss nuke, them right away and then teleport out, into a different area and teleport back in to reset that timer. Team up with Sharon and you'll get more.
Normal Mode: Suitable for solo players or those not fully equipped.
Hard Mode: Recommended for players who are well-equipped and seek higher rewards. Offers a significantly better drop rate for Macromolecule Biogel.
Tips
1. A team can handle Hard mode more efficiently but ensure your session is set to private if you prefer not to team up with random players.
2. Upon entering the outpost, quickly activate any necessary mechanisms to trigger the boss's appearance. The faster you spawn and defeat the boss, the quicker you can farm the Macromolecule Biogel.
3. Use gear and skills that maximize damage output and survivability. This is especially crucial in Hard mode where enemies are tougher.
4. Destroy the three devices around the Boss and lead the Boss out of the boundary, you can easily kill him. It should be noted here that before leading the Boss out of the boundary, consume about half of his health before killing him, otherwise the system will prompt that the mission has failed. You can repeat this process all the time.

Mixed Energy Residue
To efficiently gather Mixed Energy Residue, you should focus on opening the Encrypted StorageBox found in the Agna Desert. Using Enzo can improve cracking efficiency.
Tips
1. Navigate the Agna Desert, and use the in-game tools to locate these encrypted storage boxes. They are usually indicated by specific markers or signals.
2. The game often provides audio cues when you are near an encrypted box. Use this to your advantage to quickly locate and access the boxes.
3. Ensure that you have enough space in your inventory before starting your farming session to avoid having to discard items or make multiple trips.
Upon successfully decrypting a box, it will open to reveal various items, including Mixed Energy Residue. The amount of residue can vary, but typically, you will collect a few units per box.
Repeat the Process Continue searching the desert for more encrypted boxes. You can optimize your route to cover multiple boxes in one outing to maximize efficiency.
Crystallization Catalyst Blueprint

It is recommended to kill the Devourer in hard mode, he has a 20% drop rate of Crystallization Catalyst Blueprint, and it is not very difficult. Amorphous Material Pattern recommends choosing 76 or 78. No. 76 has a 6% chance of getting the Ultimate Gley Stabilizer Blueprint, and No. 78 is the Ultimate Ajax Code. Relatively speaking, it is recommended to choose No. 76. If your skills and equipment cannot complete the hard mode, you can also choose the cheap TFD Void Intercept Boost.
Advanced Neural Circuit

Recommended Battlefield Mission: Order's Veil in White-night Gulch, because Majors often appear, it is very easy to kill, very suitable for obtaining Advanced Neural Circuit, and the drop rate is also relatively high. It is recommended to use a descendant with a large-range AOE skill.
- Normal Mode: Ideal if you prefer less challenging encounters. The drop rates are decent and you can handle larger groups of enemies with ease.
- Hard Mode: Provides higher drop rates and more challenge. Opt for this if your gear and skills are sufficiently advanced.
After clearing the area and collecting drops, reset the mission or exit and re-enter to make the Majors respawn. This allows for continuous farming. If possible, team up with friends or other players. A coordinated group can clear areas faster and handle Hard Mode more effectively, increasing the overall efficiency of your farming efforts.
Tips:
1. Ensure you have enough room in your inventory for multiple runs to avoid having to return to base frequently to manage your inventory.
2. The quicker you can complete each run, the faster you can gather Advanced Neural Circuits. Enhance your character's speed and damage output where possible.
