Detailed Description

An ancient catalyst from Liyue's arsenal. The batch number has faded and no records exist to confirm the date of production. The disc represents the cosmos and thus takes a circular form. At the center is a piece of Cor Purum, representing a heavenly body suspended in the firmament.

After the great chaos subsided, sinister forces still remained in the world. Thus, people abandoned traditional martial arts and tools and espoused the supernatural arts.
But the techniques used in catalyst production were antiquated, having remained unchanged in over a century. Thus, the catalysts of that age were fragile and broke on first use.
The thaumaturges flocked to Liyue and pleaded with Yun Hui, head of the house of Yun, to design a new type of catalyst for them. Yun Hui proceeded to add a catalyst to the then-new series of improved weapon designs known as "the prototypes."

The disc is made of wood and rare ore. The Cor Purum in the
center was a gift from the thaumaturges.
Cor Purum is produced by firing Cor Lapis in an urn for seven days squared (that is, forty-nine days) and then steeping it in fresh water drawn from a mountain spring for a further seven days squared.
The dual purification of fire and water renders Cor Purum unbreakable, and the thaumaturges also believe it allows the stone to act as a vessel for primordial cosmic energy. A catalyst with Cor Purum at its core can channel cosmic energy with the turning of the disc. Twelve full turns works the energy into its purest form.

Yun Hui observed that the Cor Purum had a warm, golden glow like that of amber. After discussion with the thaumaturges, he proposed to name the catalyst "Prototype Amber."
Thereafter, all catalysts made in Liyue were modeled on Yun Hui's prototype.
