CLASS: BIOCONSTRUCT

   This primitive but still effective biological weapon produces a sharp smelling, rusty yellow powder in its bloated body which burns organic matter and rapidly deteriorates metal on contact, slowly dissolving both into a crystalline dust that the Gasjack re-inhales with a long, noisome snort. Dangerous though they are, they spook easily and have a reputation for stubbornness; if a Gasjack can avoid putting itself in greater danger than its master, it often will.

   Stories tell of entire deserts created by vast armies of these monsters at some forgotten point in time, stories supported by the toxic yellow dust storms still swirling over the deepest wastes.
