A custom-cut frequency crystal whose refractive qualities are specifically suited to boosting yield when mining Complex Ores such as Arkonor, Bistot, Spodumain, Eifyrium, Ducinium, Hezorime and Ueganite. Due to their molecular make-up and the strength of the modulated miner's beam, these crystals will deteriorate through extended use. Can be loaded into modulated mining lasers only. Type A crystals are used with modulated mining equipment and provide steady yields, with low residues and high reliability. A crystal choice for methodical mining operations prioritizing resource utilization over time.
