Shields deflect blast

Farsight zoomed in. The tau's flesh had been transformed. It was registering as glass, vitrified like stone under intense heat.
Features twisted in confusion and anger, Farsight swept his fusion blaster low to cut the nearest Molochite into an explosion of hissing pink viscera. Two smaller creatures burst from its corpse, blue-skinned instead of pink. Each was still decorated with gaudy jewellery. These strange infants too hurled fire. Odd energies crackled from Farsight's shield generator.
He glanced at the shield's custom sub-program in confusion and mounting panic, but it was still registering gold, at eighty-seven per cent integrity.
The high commander leaped forward, twisting mid-air, and came down hard in a double-stamp. Each foot crushed one of the two blue-skinned pyromaniacs into puffs of sulphur-scented flame. One of the fires caught on his Crisis suit's ankle. He twisted the XV8's sensor-head to catch a glimpse. The fire was climbing – literally climbing, with limbs of flickering light – up his battlesuit. He swatted the cackling fire-thing with the barrel of his plasma rifle, then stamped it out for good measure.
These creatures defied analysis.
