How to complete the Energy Extraction Device Challenge west of Port Ormos in Genshin Impact

In the west of Port Ormos, you'll find an enemy encampment with an Energy Extraction Device that can be diffused with the help of control keys. Reference the image below to find the exact location of the Challenge. Since the area is swarming with enemy Eremites, make sure to bring a battle-ready team.

Once you get there, you'll find a mechanism called an Energy Extraction Device. Your goal is to find the other two keys to deactivate the Device.

First Control Key location

Assuming that the Energy Extraction Device is in front of you, turn left and climb the wall. Turn left again to find a broken pathway leading to the floor below, where you’ll immediately spot the first Control Key. Approach the Control Key to obtain it. Some enemy Eremites will spawn—defeat them to open up an exit route.

Second Control Key location

Climb the ladder behind the Energy Extraction Device, then turn left to find the broken part of the building. Enter the room to claim the second Control Key. Some enemy Eremites will spawn—defeat them and head back to the location of the Device. 

How to guard the extractor until it shuts down in Genshin Impact

Interact with the Energy Extraction Device to begin the next phase of the Challenge. In this segment, you need to stand beside the mechanism until the purple gauge on top of it fills up. However, enemy interruptions will force the gauge to stop moving, so you must defeat all the Eremites that get in your way. When there are no enemies, make sure to stand beside the Device, as the gauge will not fill up if you’re too far away. Once the gauge is full, the challenge will be complete, and you’ll be rewarded with an Exquisite Chest.
