Mastering the 'An Eye for An Eye' Quest: How to Acquire Energy Storage Devices in Genshin Impact

Obtaining the Energy Storage Device and unlocking the Research Terminal is a crucial part of the "An Eye for An Eye" quest in Genshin Impact. To progress, players must gather three Energy Storage Devices and utilize them on three distinct Terminals to eliminate barriers obstructing access to the Research Terminal.

This step is relatively straightforward and guided by map markers in Genshin Impact, making it easy to follow. However, players must exercise caution when dealing with the Flying Energy Thief, as it can deplete the energy from the device, rendering it useless.

Here's a detailed guide on how to acquire the Energy Storage Device and unlock the Research Terminal ahead in Genshin Impact:

After successfully escaping the Abandoned Production Area in Genshin Impact and diverting the guards' attention, your group will reach the Geode Mine Shaft. Here, you'll encounter three barriers that can be removed in a specific order: right, left, and then the one in the middle.

Start by approaching one of the Energy Storage Devices and picking it up. Then, sprint straight ahead and make a right turn. Quickly collect the Mysterious Ore to the left and proceed to the right side, where you can place the storage device next to the first Deactivated Research Terminal. Don't forget to activate the console by pressing "Break Seal" to open the path to the other Research Terminals.

Now, return to the initial location where Caterpillar is positioned and pick up the second Energy Storage Device. Similar to the previous one, move straight ahead and take a sharp left turn to locate the second Deactivated Research Terminal. Be cautious in this area as the Energy Flying Thief patrols more vigilantly in Genshin Impact. If you encounter one, try to navigate around the area to evade the thief.

Lastly, return to the starting point and collect the third Energy Storage Device in Genshin Impact. Simply proceed straight ahead and make a left turn at the end to find the third Deactivated Research Terminal.

As you approach the exit, a barrier suddenly materializes, trapping everyone inside the mine. It is revealed that Noailles has caught up with your group, and players must engage in a battle with him. Although Noailles' health is displayed like that of a boss in Genshin Impact, defeating him is relatively straightforward, especially with Caterpillar's assistance. A few solid attacks from a decent damage dealer should suffice. After a while, Estienne appears and releases the barrier, allowing everyone to escape. Dive into the water and use the current to exit the Fortress of Meropide, successfully completing the "An Eye for An Eye" quest.
