Mist Veiled Gold Elixir is Weapon Ascension Materials used to ascend weapons, increasing the stats and max level. Higher-rarity materials can also be crafted with Alchemy by combining lower-rarity materials from the same group.
Elixirs are in fact pills made from metal alloys. They were created by the adepti, and are able to grant weapons transcendent powers. However, they are rarely seen in the world due to the hubris of the practitioners of martial arts, who prized the ways of combat over the paths of the adepti.
How To Get
Mist Veiled Gold Elixir is obtainable from crafting and dropped as a random reward from completing the Hidden Palace of Lianshan Formula domain near Mingyun Village every Tuesday, Friday, and Sunday.
Mist Veiled Gold Elixir can be crafted in the Alchemy table in Mondstadt or Liyue using 3 pieces of Mist Veiled Mercury Elixir.
