Description
Adamantite among Orichalcum were ultra rare metals in the New World. Though by YGGDRASIL standards they were a grade below the Prismatic Ores. In addition Adamantite is the highest rank an adventurer could reach.

Appearance
In the Anime, adamantite is portrayed as a polished dark blue to black metal.

Abilities
Adamantite was a rare magical material which was generally known as the hardest metal known in the New World. The metal was highly expensive, even making a small piece like an adamantite plate was astronomical. Adamantite like most metals can be melted with extreme heat.

Trivia

 * So far only six examples of Full Platemail cast out of Adamantite exist in the Overlord series: Guardian Armor, armor worn by the Four Imperial Knights, and Zaryusu Shasha's armor.
 * In the official Italian light novel translation and the official subtitled translation of the anime, adamantine is accidentally translated as "adamantio" (in English "adamantium", the fictional metal created by Marvel Comics). This mistranslation appears throughtout all light novels and all seasons of the anime.
