Vulcan
Matching the size of other modern colossals, the Vulcan is no less than a rolling alchemical arsenal. Sloshing hundred-gallon vats within its structure allow it to unleash an array of alchemical attacks. A series of dispersal nozzles along the chassis can blanket a large area in a debilitating fog of toxic gas. Its primary weapon, the Aqua Mortuum rocket, leaves trails of alchemical poison in the air and detonates with a burst of lingering toxins, while its smaller vitriolic deflagrators hose down squadrons with concentrated, high-molarity acid.
