Bolas - Fire breath melts metal construct twice as tall as a man

And then it rose, a mere box no longer, but a construct of enormous size, humanoid but twice as tall as a human, inhabited by whatever spirit Tezzeret had called from the outer void. It stepped forward with a series of clicks and whirrs, ready to engage the barbarians in battle.

And from above, a shadow spread over the ice-veiled sun. Nicol Bolas circled once, wings outspread as though to clutch the world entire, and melted Tezzeret's forged ally to slag with a single fiery exhalation, filling the chasm with choking fumes.

The flames never came near the artificer or the mage, of course, for Bolas was indeed still bound by the ward. And again his laughter echoed through the canyon as Jace and Tezzeret ran once more, the barbarians close on their heels.
