Mineral Armor

Mineral Armor is an Armor set that increases the amount of blocks that you can mine with your pickaxe. This armor is crafted with Refined Minerals, that drop from ores during the Mining Fiesta event, which can occur when Cole (or Foxy and Jerry) is in office.

Crafting
Requires: Hardened Diamond Armor + 24 Refined Minerals.

Ability
The ability of items in this set is unique. 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.

Unaffected Blocks
All Pickaxe-mineable blocks on public islands WILL be affected by this armor set's effect. Obsidian in The End and the Deep Caverns, Block of Diamond in the Deep Caverns, and Glowstone in the 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

 * Mining blocks that were replaced in the last few moments will prevent the player from earning XP for a short while. This bug is present across the entire game, but is exacerbated by this armor set's ability, as additional blocks will be broken.
 * Because of this bug, players wishing to maximize XP, should consider mining End Stone. This is because End Stone is replaced with Bedrock, so this bug will never trigger.

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 is 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 net upwards of 400,000 mining xp per hour, and even 600,000 mining xp per hour when using a Lvl 100 Silverfish, and a Refined Stonk with the Compact enchantment. If you’re lucky, Cole will be in office and a Mining Fiesta will be active, which multiplies your XP gain by 4, increasing your XP yield to 2.4 million per hour.
 * Although it isn't stated in the armor itself, the Mineral armor special effect does not work in private islands.
