DartCraft by bluedart
DartCraft adds one, and only one new ore to Minecraft: Power Ore. When you mine this ore you receive 2-4 “Force Gems” (fortune affects this) which can be used to create Force Ingots from which specialty tools are crafted, or even squeezed into Liquid Force which can be used in several DartCraft machines.
