Ignores burning oil

Something orange glowed in the fog of brick dust. Ryn thought of bombardier beetles and their chemical ignition system.
Fire roared through the air, but to her side. The blistering-hot film spewed a wet trail of flames, covering the tarpaper rooftop. Children live here. She had to take that weapon out, or the building would burn.
Ryn hefted a loose brick, flicked through the cloud, and launched a flying kick that planted both heels into the creature’s torso. It knocked him stumbling out of the debris cloud, burning oil thrown into the air, spattering down in fat drops. It hissed against Ryn’s cloak and clung to her forearm. She ignored it.
Out of the cloud now, she saw how his fire worked: his puffer throat filled with fluids from chambers in his guts and when he spat the flaming gel, it sparked on contact with oxygen.
She chucked the brick into his gaping mouth where it lodged firmly between his teeth. His puffer throat swelled, but couldn’t contract. The fluids backed up, dribbling weakly from the corners of his mouth.
Ryn’s claws flashed through his throat and she booted him off the building. He fell into an alleyway.
About halfway down, the glass-clean cut in his throat forced the chemicals from his guts to mix and let just enough oxygen seep in. The explosion started inside him, roaring out of his throat, mouth, and eye sockets, finally erupting like a wet bomb from his center. He landed in a dumpster and Ryn lost track of him as he detonated twice more in geysers of liquid fire.
Her cloak shivered, smothering the fire she carried on her shoulders and forearm. The rooftop still burned, and she launched a tether from her cloak to a water tower one building over. It smacked a wooden strut and she gave it a mighty pull. The strut bowed and snapped, the tower crashing down, overturning its contents on the adjacent flames. Water surged up to Ryn’s hips and she had to anchor with three more tethers to keep from being carried over the building side with the deluge.
