Lumenspar is an item that can be found in the The Chasm: Underground Mines. It is used to upgrade the Lumenstone Adjuvant.

When a Lumenspar is within close proximity of a player, an icon will appear on their minimap along with a sound effect, similar to the oculi. Once the player reaches level 8 on their Lumenstone Adjuvant, it can be used to search for nearby Lumenspar.

80 Lumenspar can be found throughout the underground mines. When the player upgrades the Lumenstone Adjuvant to the highest level, they will be granted the Chasmlighter achievement Arch-Illuminator.

For the rewards and amount needed for each offering level, see Enhance the Lumenstone Adjuvant.


See the Teyvat Interactive Map for locations.
