Chunk of Aerosiderite 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.
When Khaenri’ah was destroyed, a great sinner created endless monsters with alien, dark blood flowing through their veins. They rampaged across the land, destroying all in their paths. Their lives were mutations, caused by powers beyond this world. The black serpentine dragon Durin that attacked Mondstadt was such a mutation.
