Juvenile Jade is an ascension material in Genshin Impact. The only character who uses it, at the moment, is Xiao, and it is not currently needed for any weapon ascensions.
It only comes from one source in the game, the Primo Geovishap. This is a new world boss that was introduced in Genshin Impact 1.3, and it can be quite a challenging fight if you are not prepared for it. Juvenile Jade will only drop from Pirmo Geovishaps that are Level 30 or higher.
Where to find the Primo Geovishap
You can find this boss fight in Tianqiu Valley in Liyue. As we said, it is a tough fight, and the creature has a range of attacks that you will need to be prepared for.
