Adamantite Ore

Adamantite Ore is the highest tier of the three new Ores available in Hardmode, and is the rarest and most valuable of the three. It spawns upon the destruction of every third Demon Altar. A Mythril Drill or better is required in order to mine Adamantite. It is used to craft the Adamantite Forge and Adamantite Bars. An Adamantite Forge, crafted from 30 Adamantite Ore and one Hellforge, is required in order to craft Adamantite Bars.

The ore will not appear in the world until the player destroys three Demon Altars with a Pwnhammer. Destroying any Demon Altar will "bless" the world with deposits of either Cobalt Ore, Mythril Ore, or Adamantite Ore. These Ores will then be found randomly like any other, with Adamantite being the most rare.

Adamantite is colored red and can be found near the bottom of the Cavern layer, at the same depth where Lava begins appearing. To craft all Adamantite equipment, the player needs to gather 144 Adamantite Bars, plus thirty ore for an Adamantite Forge, for a total of 750 Adamantite Ore.

Trivia

 * Adamantite gets its name from "adamant" which has historically been used to describe exceptionally hard materials such as diamond. Adamant and variations have widely been used to describe metals and materials with diamondlike durability in fantasy, science-fiction, and mythology, from as far back as "adamantine" in ancient Greek mythology, to the "adamantium" of Marvel Comics (first appearing in Avengers #66 but made famous by the popular X-Men character Wolverine, whose skeleton was infused with "adamantium").
