Genshin Impact: All Lumenspar Locations in Chasm Main Mining Area
The first location is on the north entrance of The Chasm: Main Mining Area. To get the lumenspare, just hug the left side of the wall and you will see the stone on the ground.

The second and third lumenspar stones can be found right after you collect the first one. Simply jump off the cliff from where the first one is, and you can see both spars.

The next lumenspar stone is close to the northern teleport in The Chasm main mining area.

Just glide down from the teleport and you will see the lumenspar in the middle.

The next lumenspar location is north on the map. To get to this stone you must jump in the water where it’s shown in the image, and go inside a cave where you will find the spar in the middle of the road.

The next lumenspar will be located at the exact spot where you start off to go for the previous one. Inside the water you will see the blue rock shining.

The next location will be on the northern border of the map. Here you will find a treasure map fragment that will open a secret passage to get more lumenspar. The map is split into two pieces.

You will see the map hanged on a log right by a camp of some treasure hunters.
The second fragment of the treasure map is located north of The Chasm’s Maw.

Go to this location where you will find an abandoned camp and the treasure map fragment will be placed right with a pile of goodies.

Once the map has been collected, you can open it and see where it will lead you. Head to this specific location where you will need to fight off some enemies.

Burn the wheat that you see behind the chest to open the secret passage and get inside the cave.

Once you get inside, you will see the lumenspar standing right before a gate. Inside the cave, you will also find a precious chest and some other goodies that you can loot.

Once you’ve opened the secret passage on the gate, you will find yourself back in The Chasm: Main Mining Area. From there you can continue searching for the next lumenspar.
The next lumenspar can be located on the eastern side of the main mining area. The stone will be placed on the very edge of the cave.

The next two lumenspar can be found in the middle of the main mining area. The first lumenspar can be found on top of a rock exactly as shown on the image.

The second lumenspar for this location can be found just south and down from where the first one is.

The next one is simple to get, get to this area and you will see it on the ground.

Right in the exact area, continue going west and enter a different room where you will find another lumenspar.

Just south of the last area you were in, you can find the next lumenspar.

This lumenspar is located on the top of the wooden log of the crane. Carefully climb the log and you will collect the spar.

The next location will be east of your previous one.

Just glide down from the wooden log and make your way towards the second crane. Make sure to keep your height good because you will need to catch the stone in the air, as it’s being held on the hook.

To get to the next location, you will need to hug the right side of the wall and climb some rocks in order to get the lumenspar.

You will see the lumenspar in a small blocked-off cave. There will be two barrels in front of the blocked wall. Light the barrels up and you will make yourself an entrance.

To get to the last area, you will need to level up your lumenstone adjuvant to level 6. If that is not achieved, you won’t be able to enter this area.

Once you reach level 6 on your Lumenstone Adjuvant, this purple crystal door will open and the lumenspar will be inside the area.
