This Genshin Impact Wiki guide details everything you need to know about how to find and get Noctilucous Jade. Used as a character ascension material, Noctilucous Jades are a local specialty of Liyue, and can be found at the base of mountains and can easily be spotted due to their bright blue-looking node.
Noctilucous Jades are procured from their respective node. Being an ore, they're easily farmed if you hit them with a blunt weapon. Claymores do the job best, but there are also ways to get them without claymores.
Zhongli's elemental skill works really well for ore farming, as well as Klee's charged attacks. Kazuha's elemental skill propels him upwards giving him an opportunity to do a plunging attack which also does quite a bit of damage for ores. Venti's elemental skill, when held, creates an updraft that Venti himself or another character can ride. Use these for plunging attacks.
