One can predict what foes are on the battlefield by how they sound. Foot soldiers clang weapons on shields as they march. Cavalry is marked by a rapid drumbeat of hooves. Armies with great monsters under their command don't try to silence their hair-raising screeches.

No sound prompts as much caution as the steady clicking of gears and hiss of billowing steam, for the only thing that accompanies that chorus is an aurocan: a mechanical creature created in the shape of a massive six-legged bull prone to exploding when destroyed. The aurocan's greatest strength is how its head can detach from its body to rain down scalding steam from above.
