Demonic Armored Warrior Swings Scythe on Rainy Rooftop

the prompt

A highly cinematic 5-second 4K video of a massive demonic warrior in ornate, battle-worn silver, red, and gold armor with sharp spikes, glowing red accents, and a long segmented dragon-like tail. He wears a menacing horned helmet with glowing eyes, flowing white and red tattered fabric from his waist, and golden greaves.
He stands powerfully on a wet, reflective stone rooftop during a heavy rainstorm at dusk, with a dramatic futuristic city skyline glowing in the background under dark stormy clouds. Rain is visibly pouring down.
Sequence of dynamic action (smooth, epic, slow-motion cinematic style with dramatic camera movement):
Starts in a wide heroic stance, massive crescent-shaped scythe weapon (intricate spiked blade with glowing orange energy) resting on the wet ground, sparks flying.
He dramatically swings the huge scythe upward in a powerful arc, sparks and water droplets exploding everywhere.
Raises the weapon high above his head with both hands, then slams it down into the rooftop, creating a massive burst of bright orange sparks and water splash.
Follows with a second powerful swing and final powerful pose, weapon raised high, tail whipping, rain glistening on the armor, intense sparks flying from every impact.
Photorealistic fantasy style, ultra-detailed armor textures, cinematic lighting with rim lights and volumetric god rays through rain, moody dark atmosphere, intense motion, sparks and water physics, epic boss-fight energy, no text, no logos, 5-second loopable sequence, 24fps, dramatic low-angle and dynamic tracking shots.
