Chasm Spelunkers Walkthrough

Enter the Mines of The Chasm

After breaking the seal, simply follow the mission marker and ride the elevator down. Once below, a scene involving Jinwu and Zhiqiong will begin to play, and you will be tasked with retrieving the Lumenspar that is shown in the cutscene.

After acquiring the Lumenspar, return to the camp for another scene, and you will now be able to use the Lumenstone Adjuvant.

Look for Clues to Uncle He's Whereabouts

During the scene with Jinwu, she mentions Uncle He, their miners' senior. She will then ask you to help her in searching out some information about his whereabouts.

There will be three locations indicated on your map that you can investigate; simply go to the spot and follow the instructions below to acquire some clues.

Diary Fragment Clue #1

The first Clue is on the same level of the teleport waypoint. Walk along the bridge to the location until you see some Oozing Filth and a Geovishap. After defeating the Geovishap, turn left and you should see the box with the Diary Fragment.

Diary Fragment Clue #2

The second Clue is on the lowerst level by some boxes, barrels and a Lumenlamp. The Diary Fragment should be on the side of a box full of rocks.

Diary Fragment Clue #3

The third Clue is on the lowest level near some Treasure Hoarders. The Diary Fragment should be there on a cart beside a Lumenlamp and a rack of weapons.

Report Back to Jinwu

After you've gathered all three clues, return to Jinwu for another scene; she'll then ask you to look for Zhiqiong, who has gone off on her own.

Look for Zhiqiong and Speak with Her

Start your search for Zhiqiong by heading east of your current location. When you find her and speak with her, she will ask you to assist her with two commissions.

To complete Zhiqiong's Commissions, you must investigate the anomalies, and free the trapped person. Check the guides below to get you started!
