A custom-cut frequency crystal specifically suited to boosting yield when mining for Erratic Ores such as Prismaticite found in Phased Fields. These crystals will deteriorate through extended use. They can only be loaded into modulated mining lasers. Type B crystals are used with modulated mining equipment to achieve faster yields, at the cost of higher residues and lower reliability. An appropriate choice for rapid extraction operations prioritizing speed over resource utilization.
