Genshin Impact is an open-world action and adventure RPG developed by Mihoyo. The Chasm is the new region introduced in Version 2.6, bringing with it a great number of quests, puzzles, and chests. Lumenstone Ore is needed to level up the Lumenstone Adjuvant. Leveling up the Lumenstone Adjuvant unlocks various features which can make exploring the Chasm: Underground Mines easier. Moreover, leveling it up also gives tons of good rewards like Fragile Resin, Intertwined Fates, Acquaint Fates, a Crown of Insight, and a Northlander Billet Trove. This guide will help you find all Lumenstone Ores in Genshin Impact in the Chasm.
Lumenstone Ore #1
The First Lumenstone Ore can be obtained by completing the quest “Chasm Spelunkers”, which is a part of “The Chasm Delvers” quest series. After destroying all the Bedrock Keys, enter the Underground Mines from the hole in the center of The Chasm. Once you have completed this quest, you will recieve the Lumenstone Ore.
Lumenstone Ore #2


Next, the Second Lumenstone Ore can be obtained in the Stony Halls while completing the archon quest, “In the Depths, An Unexpected Reunion“. Glide down from the top teleport waypoint of the Stony Halls. You’ll find the Lumenstone Ore at the edge of the glowing pit. If you missed the stone and completed the quest, you can still go to the location to obtain it.
Lumenstone Ore #3


Finally, the Third Lumenstone Ore can be obtained during the world quest “Wherefore Did the Spritstone Descend“. This quest is the last part of “The Chasm Delvers” quest series. After opening the gate to the Glowing Narrows, go within the gate. You’ll find the Lumenstone Ore in an abandoned Fatui Tent.
Those are all the Lumenstone Ores in Genshin Impact that you will need to level up your Lumenstone Adjuvant. Moreover, you may also have to find the keys to the gunpowder storehouse for the quest after “Chasm Spelunkers”. For more Genshin Impact guides, stay tuned to Retrology.
