How To Get & Use Arkhium Stock In Genshin Impact

Arkhium Stock is an interesting and mysterious addition to patch 4.1 of Genshin Impact. As you venture forth the newly released areas of Fontaine, you can uncover mysterious ores whose purpose as the name suggests is hidden until you find all of them. The mysterious ores are scattered across the region and you’ll have to deal with some tough customers to acquire all of them.

These mysterious ores collectively form the Arkhium Stock in a process that is fairly perplexing even by Genshin Impact standards. So, if you have stumbled upon one of these mysterious ores and are stumped by what their purpose is, here is an Arkhium Stock guide to help you unravel this mystery in Genshin Impact.

Mysterious Ores Location In Genshin Impact

There are a total of 7 of these mysterious ores spread across the newly added areas of Fontaine. While finding them is a miscellaneous side quest you’ll have to undertake at your own behest, there are other quests intertwined with their locations. So, be prepared for possible spoilers.

Here’s a rundown of all the mysterious ore locations in Fontaine.

Location	Quest	Directions
Kuziel’s Clockwork Workshop	Road to Singularity	You can find a mechanical structure at the center of the village and the ore tucked away safely at the topmost part with the semicircle-shaped gear.
Mary-Ann Memorial Park	Treacherous Light of the Depths	After completing the quest head to the Abandoned laboratory, upper water area. Dive deep to reach the Abandoned Laboratory ruins, dive into the puddle to the right, and follow the current to reach the ore.
Abandoned Production Zone	Unfinished Comedy	After completing the quest you can find the ore in the area where you are tasked to locate the research terminal.
East of Mount Esus	Defeat Thorny	After you have destroyed the neural cyst boss Thorny, it drops the mysterious ore.
Experimental Field Generator	–	Climb the wall next to the generator to get the ore.
Central Laboratory Ruins	–	Dive into the square water entrance and head straight to the ruined structure with a rock and a glowing blue crack in the middle. Break the rock to get the ore.
Hilichurl Camp east of the Central Laboratory Ruins	–	You can find a mechanical structure at the center of the village and the ore tucked away safely at the topmost part with the semicircle-shaped gear.

There is no predefined order in which you need to collect the ores. As soon as you collect the 7^th and final ore, you’ll receive the achievement ‘Come on Out, Mystery Ore! Grant my wish!‘ You’ll also have the Item Arkhium Stock added to your inventory indicating that all the mystery ores have combined.

How To Use The Arkhium Stock In Genshin Impact

The description of the Arkhium Stock will reveal that it needs to be forged to unleash its limitless potential. For this, you need to first locate a forge capable of doing said task. Fortunately, there is one right beneath the New Fontaine Research Institute. Getting there, however, will require some exploring.

How To Reach Arkhium Stock Press

First, head to the waypoint where you encounter the Millenial Pearl Seahorse. From the waypoint, head down the underwater cave beyond the fountain. This will lead you to a current system which will lead you to yet another waterfall. Climb the rock beside the waterfall to reach a stairwell that ultimately leads to the underground Forge. You will have to deal with a few enemies on the way.

Use The Forge To Press The Arkhium Stock

This is the final part of the Arkhium Stock quest in Genshin Impact and involves a somewhat elaborate puzzle that involves multiple stages. The mechanism of the forge is quite complicated and seems to be connected with the entire structure.

These are the steps you’ll need to follow to get the forge going and ensure that the entire area doesn’t fall apart in the process:

• Step 1: Place the Arkhium Stock in the Forge.
• Step 2: Activate the handwheels (three in total) across the forge room till all the pressure is directed to the forge. All three pipes have a leak which will stop to indicate that the pressure is flowing the right way. The wheel of one of the pipes is on the lowest floor.
• Step 3: Activate the forging press. Once it is activated press the F key (square for PS). Timing is crucial here. You need to press the key only when the stock begins glowing orange.
• Step 4: After you have struck the stock a few times, the forge unleashes a few pyro slimes whom you will have to defeat. Then head back to the controls which will indicate that the system has overheated.
• Step 5: Break the water rocks on the lowest level to flood the entire area except for the forge mechanism. Head back to the controls and begin striking again. A couple of strikes later, the controls display another error: water has entered the system.
• Step 6: You can activate the drain control to the right and find out it has been blocked by something. You need to cut the seagrass blocking the crevice below and kill a few Red Meanies blocking the drain outlets to either side of the forge area.
• Step 7: Head back to the drain controls and drain the area. Then head back to the forge controls, strike a few more times, and voila the Arkhium Lumenite is ready. However, the last strike has destroyed a main pipe in the room flooding the entire level. So, it is time to head out.

Find And Unlock The Hidden Room With Arkium Lumenite

After you have acquired the Arkhium Lumenite, head to the waypoint near the Fontaine Research Institute of Kinetic Energy Engineering Region. Head down the chasm to its northeast and activate the gate using the Arkhium Lumenite on the lever to get the ‘Not So Strait is the Gate’ achievement and access to Bravais’ Hidden Study with lots of unique loot.
