Adamantite Ore

Adamantite Ore is one of the two top-tier ores that can spawn from every third destroyed Altar in Hardmode (the other possible ore being Titanium). In worlds where it spawns, it is the rarest and most valuable of the three Altar-spawned ores.

A Mythril/Orichalcum Drill, Mythril/Orichalcum Pickaxe, or better is required in order to mine Adamantite. An Adamantite Forge, crafted from 30 Adamantite Ore and one Hellforge, is required in order to craft Adamantite Bars. Adamantite Ore, as well as Adamantite Bars, can also be obtained by opening crates, eliminating the need for a higher-tier pickaxe. Adamantite Ore is also dropped by.

Crafting all Adamantite items requires 174 Adamantite Bars, plus 30 raw ore for an Adamantite Forge, for a total of 696 / 900   Adamantite Ore.

Tips

 * Adamantite is a common sight on the ceiling of the Underworld, especially after having smashed many altars. Looking near large pools of lava can help, as lava produces enough light to see many Adamantite deposits.
 * It is beneficial to use Spelunker Potions and look for Adamantite near the bottom of the world.
