Imag Crystals[sic] (where imag is first four letters of imagery) is a set of component items added by AcademyCraft. It has three variants, distinguished by their purity: low, middle, and high. Low-purity Imag Crystal is dropped by Imag Crystal Ore, while both Middle-purity and High-purity Imag Crystal are created by refining low-purity or mid-purity crystal in Imag Fusor, respectively, as shown below. Those three types of Imag Crystal are all used in recipes of AcademyCraft machines and Energy Unit.
