Well Peacock ore is not really much as a concern as is Coke atm. Peacock ore is only used atm to make Rose Gold Inogts, which are only used to make "Flawless Rose Gold Clasps" (HQ of Rose Gold Clasps), then can be synthesized into Rose Gold Earrings.

I completely agree with Crimzon.

I think it was just over 700 quality? It did not HQ but that is still decent enough odds (including a 19% chance at DD).

I do not believe there is a HQ coke in the game like gathered somewhere. The purpose of this is twofold. #1 It keeps the "difficult synthesis" difficult since you cannot just go out and mine HQ coke, ultimately making these items easy to synth. The fact that the coke is only NQ makes sure that a crafter DOES need to have some skill/luck to HQ the ingot, or to HQ the part with NQ ingot.

#2 Since it's only sold from NPC for 100,000 per, it also acts as one of the few gilsinks added to the game to balance out all the gil coming into the economy.

Competition, the Mother of Innovation
After the establishment of the Grand Companies, each city turned an eye to crafting quality arms and armor with which to outfit their respective forces. A growing number of adventurers can be seen clad in this official equipment as the Grand Companies continue to reward faithful service.

There are those, however, whose livelihoods have suffered from the availability of such equipment—the armorers and weaponsmiths who rely upon the custom of adventurers. These craftspeople began searching for a means to rival the companies’ superior wares, and eventually discovered their salvation in working with darksteel ore and hippogryph skin.

Though well known for their incredible strength and durability, these materials are notoriously difficult to shape and deemed ill-suited for mass-production. After much experimentation and deliberation, however, the masters of each guild developed improved crafting techniques. Thus were they able to forge a new series of unique items.

The invention of new crafting methods has made such arms and armor possible, but the process is still said to test the skill and patience of even the most seasoned smiths.
