Refraction Mod 1.12.2, 1.10.2 is a mod that is based on the manipulation of light and lasers. You do so by making arrays of magnifiers to collect sunlight into focused beams or by making laser blocks that require glowstone. Light beams in this mod can be split and merged using half mirrors, prisms, and reflection chambers in order to produce different colors of light, and colors of light in the mod all have special effects that will ensure you no boredom ever. For example, a cyan light beam attracts any entities towards the source while a purple beam disperses entities away from the source.
