An Eradication Beamer is a specialised weapon utilised exclusively by the warriors of the Skitarii Legion of the Adeptus Mechanicus. Only found mounted on Onager Dunecrawlers, when fired, the thin yellow beam of an Eradication Beamer widens as it projects outwards from the weapon's distinctive muzzle.
Those in further out from the weapon will be ravaged on a molecular level by its impossible technologies, whilst those closer by are simply atomised, their physical forms scattered to the hot winds of war without a sound.
