Adamantite (アダマンタイト) is a metal found in YGGDRASIL and the New World.


Adamantite among Orichalcum were ultra rare metals in the New World.[1] Though by YGGDRASIL standards they were a grade below the Prismatic Ores. In addition Adamantite is the highest rank an adventurer could reach.


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


Adamantite was a rare magical material which was generally known as the hardest metal known in the New World.[2] 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.[3]
