The Beam Rifle is one of the newest weapons that has been developed. In particular, its ability to collect high levels of energy in one place and fire it all at once was a state-of-the-art technology that had never before been possible. Components from the Colossus Stunning Beauty have made this technology possible.
The Eye of Judgement, the Stunning Beauty's energy processing component, allowed a highly concentrated beam of energy to be shot forward in a deliberate manner. Albion did not have the ability to mass produce a component with such high energy and heat resistance with its current technology.
The diverse Beam Rifles that would be created later were inspired by this very technology, but due to the use of lower spec mass-produced components, it was rare to have a rifle that had the high power and performance of Clairvoyance.
