Phosphor blast pistol

A Phosphor Blast Pistol

Phosphor Weapons are an ancient and very deadly form of unique weapon utilised by the armed forces of the Adeptus Mechanicus. Though the crawling horror of what were known in ancient times as Phosphex Weapons is all but forgotten in the Imperium of the late 41st Millennium, the blinding white fire of Phosphor Weaponry is still utilised by the warriors of the Skitarii Legions to mark out high priority targets amongst battlefield murk. If those struck by the burning, incendiary spheres fired by these weapons are not killed by the initial trauma, they are soon felled by the light-guided volley that follows.

Phosphor Weapons range from the hand-held Phosphor Serpenta favoured by many Tech-priests, to the Heavy Phosphor Blaster mounted upon Onager Dunecrawlers. The burning white spheres that shoot out from Phosphor Weapons cling tenaciously to their targets, sizzling wildly as they melt into flesh or burrow through armour and exoskeleton alike. More often than not, it is these luminagenic orbs that deal the death blow. Even if a target proves tough enough to survive the burning pain, the phosphorescent glow these spheres exude can guide an ally's volley to strike the same target.
