Item Story

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.

      I mean it can give u more energy if u refine it which means u can get ur burst off more often, it should only have an 8 second downtime so near enough the same as hu tao, as long as u have a bit of energy recharge in there or electro resonance / favonius weapons

    If your planning for a full healler should she would be fine but the 4pc bonus would benefit kokomi only the 2pc would thus I think it’s more effective for 2pc heart of depth and 2pc maiden for every part of the passive to be used

    Everybody all hyped up about this being Kokomi’s BiS weapon, but what about 4pc maiden Healer Ningguang with this?

    so in terms of potential dps, this weapon has only 100 attack less than the other one (plus 8% hp bonus.. nothing)
    lol
    getting a 5star for so little…

    At R3, How much energy is the weapon capable of regenerate in total? Does anyone knows?

      • Kalatash on 28 July 2021 at 7:45 pm
      • Reply

      It appears that the energy return pulses 3 times, so I would assume R3 would return 15 energy.

        So… R3 Amber turns her burst into 55 energy cost?

        • Power Creeper on 16 August 2021 at 5:29 am
        • Reply

        Another possibility is if the initial burst also regenerates energy, that would mean 4 pulses within 6s. For example at R3:
        0s: 5 energy
        2s: 5 energy
        4s: 5 energy
        6s: 5 energy

        Total: 20 energy

        Judging by the wording, I would assume the former (15 energy) is correct, but it would be nice if someone could test this out to confirm which numbers are correct.

    The new 5star catalyst will allow KKomi to deal more damage with normal attacks, but this 4star weapon will refund consistent energy in shorter duration and also heals party members passively.
    So Prototype Amber is better for Quickswap KKomi.

    I’m glad another 5star character best weapon is not tied exclusively to a limited 5star weapon (looking at you, HuTao).

      It is also good for sustained damage on her burst state, for quickswap teams Thrilling Tales of Dragon Slayers probably is better. At least we have 2 really good F2P options. I would go for the Prototype because it gives you more HP and Energy Recharge, if it is good, i’ll refine it to R3.

    Kokomi’s F2P BiS weapon!

      • Luneward on 25 July 2021 at 4:25 am
      • Reply

      Possibly even her BiS weapon, period. There’s only an 8% total HP% difference between this and her 5* weapon, and I’m not sure the extra NA damage on the 5* weapon can compete with the Amber’s ability to get her burst off cooldown more quickly.

        her 5* weapon restores energy too

          • Kalatash on 28 July 2021 at 7:50 pm

          That one returns energy based upon how many hits you can score in the time frame and it doesn’t increase with refinement (though I don’t judge 5* weapons on how well they refine), while this one is guaranteed energy regen. Eyeballing the numbers (and Kokomi’s apparent attack speed) I think that the 5* might return as much energy as R1 Amber IF you hit every hit that you can in the 12s window.

        • It’s cool though on 12 August 2021 at 12:25 pm

        I wouldn’t go that far. It’s a great weapon but not better than the five star. Having another buff based on HP% to her autos is very nice. She gets a healing bonus increase which increases her damage and healing. Higher base attack. And still decent energy regen. It’s still her f2p best and a very solid comparison for being craftable. But it’s definitely not her BiS period.
