Kai Hellspear
From Warhammer 40k - Lexicanum
Kai Hellspears are Chaos-corrupted weapons that function similar to lasguns, but instead emit a searing beam of Warp energy. These beams not only cut through the armour and bone of their victims, but will also rend away their souls as well. No one knows where the Kai Hellspears originate from, but it is assumed to be a terrible and corrupted place, to be able to produce such weapons.[1]
