A custom-cut frequency crystal whose refractive qualities are specifically suited to boosting yield when mining Exceptional Moon Ores such as Xenotime, Monazite, Loparite, and Ytterbite ores. 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 B crystals are used with modulated mining equipment and achieve faster yields, with high residues and low reliability. A crystal choice for rapid extraction operations prioritizing time over resource utilization.
