Lumenspar in Genshin Impact is an item that can be found in the Underground Chasm. It is theorized to be a fragment of a thing that once existed in Dragonspine. Zhiqiong expects that there's an ancient civilization somewhere deep in the Underground Chasm. Later on, players will affirm this idea by discovering an ancient upside-down city.

Furthermore, in the last section of The Chasm, Travelers will also find a Skyfrost Nail, the same one people can see in Dragonspine. Therefore, there's a large chance that the theories mentioned by Zhiqiong and Iris are both correct. In The Underground Chasm, there are 80 Lumenspar available to collect. Here are all the locations of the Lumenspar in Genshin Impact.

Lumenspar in Genshin Impact is used to upgrade the Lumenstone Adjuvant. Each level requires players to have eight Lumenspar. There are a total of 10 levels for the gadget. All level grants the same 200 Adventure EXP, 10 Mystic Enhancement Ores, and 50k Mora, with a unique reward at each level:

  1. A Fragile Resin
  2. Two Acquaint Fates
  3. Two Philosophies of Prosperity
  4. A Crown of Insight
  5. Two Philosophies of Diligence
  6. Two Acquaint Fates
  7. Two Philosophies of Gold
  8. Two Intertwined Fates
  9. A Northlander Billet Trove
  10. The name card "Lumens: Stone of Light"

So apart from the unique items, players will earn 2,000 Adventure EXP, 100 Mystic Enhancement Ores, and 500k Mora in total.

Lumenspar is somewhat similar to Oculi in Genshin Impact, so it appears on the mini-map if Travelers are nearby. This can help ease the search, but as The Underground Chasm is made of several layers, it can be tough to find the item in some areas.

Players also need to progress in the World Quest to unlock some places in the Underground Chasm. Additionally, collecting Lumenspar during the exploration is crucial as some of the items are locked behind level 2 Oozing Concretions. This means that Travelers need to reach level 6 on their Lumenstone Adjuvant to collect all the Lumenspar.

Genshin Impact is now available on Mobile, PC, PS4, and PS5. A Switch version is in development.
