Adamantine and Mithril are such rare items that there are only three places in the game where you can get them.
One is the main gate of the First King's palace, the second is the First King's throne, and the third is the First King's very own magic wand.
Yeah! All three pieces of the adamantine and mithril mixed up together can all be found in this palace alone!
You literally have to travel all the way from the surface to this palace located deep in the Abyss Altar Area just to get your hands on these legendary rank items.
In the history of this world, it is said that this world has always lacked in terms of legendary metals, and they are extremely rare.
Even the First King only found these three pieces from his three-decade-long journey of wandering in the whole solar system.
There might be more of them, but it would take decades or even centuries just to search through the whole solar system if you want to find more of them.
