|Constraint Metal Ore|
Constraint Metal Ore is an ore block added by AcademyCraft. It can be found between layers 0 and 60. It has a mining level of Iron (requiring a Stone Pickaxe or equivalent), and will drop the ore block when being mined. Smelting the ore in Furnace or other alternatives will yield one Constraint Metal Ingot, but using a Metal Former can double the yield over using a Furnace.
