Harry vs Gate of Ice

I couldn’t fight this guy.
But that didn’t mean that I couldn’t kill him.
We flew out of the vault, and out past the Gate of Blood, and I poured it on, committing all of my reserves to the effort. I called light to my staff as I sprinted down the tunnel that emerged at the Gate of Ice, and as I went by it, I drew upon the power of the Winter mantle to slam the iron lever back up to the ON position and snap it off at the base in the same savage motion.
And then I plunged out into the two-hundred-yard-long killing field as the house-sized blocks of ice began to fall and shatter and slide and flip and smash together like some kind of enormous, demented garbage disposal unit.
“Parkour!” I screamed, dropping to a slide that took me just under a horizontally flying block of ice
as big as a freight car, then popping back up to keep running.
“Parkour!” I shouted again, bounding up onto a small block and diving over several more, ducking and weaving between them, the Genoskwa hot on my tail, casting frantically quick glances back at him, watching him close the distance inch by inch, his huge body moving with an utterly unfair amount of agility as he handled the obstacles better than I could have, even without his eyes.
And then the cold started to get to him.
It wasn’t much at first. He lost a step on me. But then in the next row of grinders, one of them clipped his monstrous shoulder. He recovered his balance and kept moving, and we were nearly through the field when I played dirty.
I jumped over a pair of low grinders, and turned in midair, just enough to point a finger back at the ground behind me and snap, “Infriga!”
I didn’t use a lot of power. Barely a whisper, really—just enough to coat a ten-foot patch of cavern floor with smooth Winter ice.
And his foot slipped.
It wasn’t a big slip. But his cold-dulled reflexes weren’t up to catching him and his balance wavered. Not much—he was, after all, running on all fours. But enough. It staggered him as he came after me, slowing his pace again.
Suddenly, there was a ten-foot wall of grinders in front of me, each individual block spinning and smashing and flipping at unpredictable intervals, and I let out a scream and leapt over it completely, high-jump-style. My shoulders brushed the top of the wall, treating me to a dandy view of another house-sized block falling straight at me from the darkness overhead, and then I bounced off the top of the wall and tumbled into the clear.
The Genoskwa grabbed the top of the wall and vaulted it easily, his huge hairy form moving with effortless power. He’d somehow anticipated its presence. He must have heard my shout and jump, and maybe the way I’d gone over it at the top. Or maybe Ursiel was helping him through his sightless chase, the way Lasciel had once helped guide me in total darkness.
But neither the Genoskwa nor the Fallen angel sensed what was plummeting soundlessly toward them.
A block of ice the size of a building came down like the hammer of God Almighty, and crushed the Genoskwa like a beer can.
I rolled to a stop and flopped on the stone cavern floor, utterly exhausted, breathing like a steam engine. But I had enough energy to turn my head to the gruesome remains being tossed about like a rag doll among the last row of grinders.
“Parkour,” I panted. “Bitch.”
