Fleet Reforge

Fleet is a pickaxe and drill reforge from Diamonite, a reforge stone the Blacksmith can't replace.¹ Diamonite is forged in the Forge in the Dwarven Mines once you reach Heart of the Mountain tier 2: it takes 3 Refined Diamonds and 6 hours. Applying it needs Mining 15.²

The Mining Spread bonus only works on blocks, not ores, so it is meant for mining things like Obsidian, Hard Stone, Mycelium, Red Sand or Ice.²
