This walkthrough will guide you through everything you need to know on how to complete the world quest “The Heavenly Stone’s Debris” in Genshin Impact 2.6. You must have your Lumenstone Adjuvant gadget upgraded to Level 2 in order to get the Storehouse Security Keys.
The Heavenly Stone’s Debris
As the quest start, speak with an NPC Jinwu in Ad-hoc Main Tunnel area as marked below. She will ask you to get her the two keys to the gunpowder storehouse so that she can help in making explosives.
Look for the two keys to the gunpowder storehouse (0/2)
Key #1
The first key is near a wooden distillery. You will find a clay vase on On top of the distillery. Climb up the distillery and break the clay vase to reveal the first key.
Key #2
Head to the area circled in the image below and jump down until you get to the watery area under the Mine. If you come across Treasure Hoarders, it implies you’ve arrived at the right place.
There you will find footprints leading to a suspicious boulder beside the Lumenlamp. Defeat the treasure hunters in the area and then go near it to find a sparkling Dig spot. Interact with the Dig location to discover an Explosive Barrel.
Hit the Explosive Barrel using an archer to blast the boulder behind it. This reveals a bright Investigate location where you may discover the second Storehouse Security Key.
Next, head to the marked location below and use the two key you have collected above to open the door to the gunpowder storehouse. Location to the door of the gunpowder storehouse is marked below.
Enter inside the storehouse and interact with the chest to collect the cannonball and bring it back to the camp.
How to make Special Unmoving Essential Oils
After brining the cannon ball back to camp, your next task is to give 3 x Special Unmoving Essential Oils to an NPC named Clitopho. Special Unmoving Essential Oil is a potion that can be crafted through a Crafting Bench.
How to Cook Special Unmoving Essential Oils
You need 2 x Cor Lapis and 2 x Frogs to make 1 x Special Unmoving Essential Oils. So as per the quest objective three Special Unmoving Essential Oils and for that you need 6 x Cor Lapis and 6 x frogs.
Cor Lapis is a Local Specialty found in the wild all over Liyue. Cor Lapis can be harvested after breaking the outer shell of Cor Lapis nodes, which are found at the base of cliffs and in caves and mines throughout Liyue. You can also purchase Cor Lapis from Changshun, the merchant in Liyue Harbor.
Release The Safety on The Cannon’s Breech
Next, NPCs assigns you the task to activate the cannon and you will need to release the safety on the cannon’s breech. Releasing the safety of the cannon’s breech is an important step to firing the cannon and breaking a boulder that blocks one part of The Chasm. To start this task, first, read the Safe Blasting Device Signaling Guide at the marked location in The Chasm: Main Mining Area.
Read the nearby “Safe Blasting Device Signaling” guide and you’ll learn about the frequency of flickering of each lamp. Each of the three lamp posts has its frequency of flickering that should be set as per the guide. You will find three lamps – the high lamp post, the middle lamp post, and the low lamp post. Each lamp should be either set to high-frequency, medium-frequency, or low-frequency as per the guide. At this point, we are not sure if the manual for frequency settings is the same or different for each player.
Interact with the guidebook on the table to read the process and instructions.
“Low lamp post, high-frequency flicker”
“Medium lamp post, low-frequency flicker”
“High lamp post, low-frequency flicker”
Next, stand at the edge of the wooden platform and observe the lamp posts. You can see that there are three flickering lamps. The nearest one is the high lamp post, while the furthest one is the low lamp post. I have marked it on the image below. You’ll notice the change of pulse in light that radiates from the blue crystals on changing the frequency.
High lamp post
Set the frequency of the high lamp post to low frequency. You can direct drop down and glide to the first lamp (high) from the observation point.
Medium lamp post
Set the frequency of the medium lamp post to low frequency.
Low lamp post
Set the frequency of the low lamp post to high frequency. Once you activate all the three lamp post this objective will end and you can continue with the quest.
Use the great cannon to destroy the sealing rocks
Once you release the safety lock, Load the cannonball along with Zhiqiong and use it to destroy the rocks blocking the path ahead. Finally head inside the tunnel. You will also find a luxurious Chest just at the entrance of the tunnel.
Activate the mechanism
Before you may continue in the next location, you must first upgrade your Lumenstone Adjuvant. The Lumenstone Adjuvant must be upgraded to at least level 5, which you may accomplish at the camp where your quest began.
After you reach level 5 on your Lumenstone, 3 additional locations will appear on the map where the cave was opened.
Fly to these three location and recharge the mechanisms. You must use the Lumenstone Adjuvant to both get rid of the Oozing Concretions or any other corruption, and to recharge the Mechanisms also. Each mechanism requires 3 Energy to recharge. You can use the Blooming Lights and totem nearby to regenerate energy for the Lumenstone Adjuvant.
Defeat the emerging monsters after recharging all three mechanisms. At the end complete the conversation with NPC, Zhiqiong to end the quest.
