Mithril

 is a resource in the Mining Collection that can be obtained in the Dwarven Mines, by mining Mithril veins, using a pickaxe with Breaking Power 4 or higher.

Obtaining
Mithril can be mined from Mithril Veins, where the inside is harder to break and gives more Mithril, but the outside breaks quicker and gives 1 Mithril. In order of weakest to hardest to mine, these veins are made up of Cyan Hardened Clay, Gray Wool, Dark Prismarine, Prismarine Brick, Prismarine, and Light Blue Wool. All ores in the vein give 45 mining exp.

Mithril Vein

The amount of Mithril you receive from mining ores is as follows: NOTE: these multipliers apply multiplicatively with Mining Fortune.

Usage
Mithril is used to upgrade Mithril Minions and to craft Enchanted Mithril, as well as to create Refined Mithril in The Forge.

Being a rare mineral, Mithril sells for a relatively high amount of money at the Bazaar and therefore is a good way to make money for both players new to the Dwarven Mines and those who aren't saving it up for Drills or other Forges.

Trivia

 * Mithril is a material from J.R.R Tolkien's Middle Earth universe. Dwarves forged it into armor that never gets pierced even by strongest blades. This is not only shown by the name of the ore but also by the existence of the Mithril Coat, which is a direct reference to Tolkien's Middle Earth Mithril.
 * Mithril is also an ore in Terraria.
