A knight in heavy armor battles enemies across a muddy field in the rain and lightning, creating a dynamic medieval combat video

Prompt

A medieval knight in heavy armor, scratched and battle-worn, gripping a longsword with both hands, breathing heavy but steady
Clashes against multiple enemies, blocking blows with brute force, pushing forward with powerful strikes and shield bashes
Muddy battlefield under stormy sky, rain falling, chaos all around
Low-angle tracking shot pushing into combat, weight emphasized in movement, whip pans connecting each clash, slow motion sparks on sword impacts, dramatic lightning flashes
