This guide shows how to find the location of all 12 Lumenspar in the Underground Waterway area in the game of Genshin Impact 2.6
Lumenspar #1
Head west from the teleport waypoint mentioned in the image below and follow the tunnel. You will find the Lumenspar floating above a broken piece of wooden equipment half-submerged in the water. It is close to a Fatui camp with a world quest!
Lumenspar #2
Head north from the last position and glide down to find the Lumenspar on the left on the top of a tree.
Lumenspar #3
The next Lumenspar is located north of the previous one. Walk along the right side of the wall to find the stone.
Lumenspar #4
Continue going west from the last location and enter the tunnel with a few mushrooms. You will find the Lumenspar on top of a tree branch, just where the tunnel opens into an area.
Lumenspar #5
Next, head into the open area after collecting the previous Lumenspar stone. On the left wall, you will find a purple portal/door. Your Lumenspar is in front of the purple door.
Lumenspar #6
Another purple door can be found on the western wall of the same area. Open the purple gate and dive into the massive hole. Glide to the bottom to locate the Lumenspar.
Lumenspar #7
After collecting the previous Lumenspar, continue to glide down to the bottom. You will find this Lumenspar on the left near a waterway.
Lumenspar #8
From the previous Lumenspar location, glide down slightly on the left where an Abyss Mages is present and a waterfall. Behind the waterfall, there are breakable stones. The Lumenspar is hidden behind those breakable stones.
Lumenspar #9
Climb up the ruined building near the teleport waypoint (wall north of teleport) to find the next Lumenspar.
Lumenspar #10
This can be found on the top of a ruined structure southwest of the teleport waypoint. This is the same location you must have visited to fulfill the world quest Perils in the Dark’s objective “Ring the two bells on either side of the ruins.” The Lumenspar is perched atop a pillar.
Lumenspar #11
Glide down from the same teleport waypoint. This time keep yourself along the left wall to locate a purple portal/door on the mountain wall. Head inside the portal to find the Lumenspar.
Lumenspar #12
Continue your journey along the left wall of the waterway going south. You will the Lumenspar on top of a pillar, near a waterfall.
