Crafting
Requires: Hardened Diamond Armor + 24 Refined Mineral.

Ability
The ability of items in this set is unique and works similar to the Heart of the Mountain Perk "Efficient Miner", though it doesn't only work with Ores, as explained below. When a player with one set piece equipped mines a block, up to two random blocks in a 3x3x3 radius (centered on the first block mined) will be mined too. Wearing each piece will mine two blocks, capping at eight blocks with a full set equipped. If a player throws their pickaxe with the Pickobulus Heart of the Mountain ability, the Mineral Armor's ability will trigger around the first block Pickobulus mines.

Unaffected Blocks
All blocks that can be broken with a pickaxe on public islands and require of 3 or less WILL be affected by this armor set's effect. Block of Diamond in Deep Caverns and Glowstone in Blazing Fortress will NOT be mined when the effect on this armor triggers. However, mining these blocks will break other affected blocks within the radius. For example, mining Glowstone with this armor equipped will often cause the player to mine Netherrack, as they are within close proximity to each other in the Blazing Fortress.

Known Bugs

 * Collection progress will not be given for 60-80% of said collections while wearing the armor. This includes ANY collection. (Example, Foraging for wood will grant 5 collection progress for 10-15 wood chopped. Even though the set should have no effect on this.)

Trivia

 * While not present in the Essence Guide, it is possible to obtain a Dungeon Armor version of this set by turning the base Hardened Diamond Armor into a dungeon item via Essence Crafting.
 * This set was best used for leveling up the Mining Skill by mining Endstone in the End. When using this method, it is best to use a Stonk Pickaxe so that Endermites don't spawn. This method can result in up to 600,000 Mining EXP per Hour. However, since the introduction of the Dwarven Mines mining Mithril is way more efficient.
 * Although it isn't stated in the armor itself, the Mineral armor special effect does not work in private islands.
