Historical Fantasy Storm Duel

Photorealistic cinematic 15-second historical-fantasy action film of two adult male warriors engaged in a sword duel on the soaked deck of a large wooden sailing ship during a violent nighttime ocean storm.
Massive waves violently rock the ship as rain falls diagonally through powerful winds. One warrior wears weathered dark leather armor and a soaked cloak, wielding a steel longsword. The second wears dark metal armor with a wet brown cloak and carries a shorter sword. Keep both warriors, weapons, clothing, and proportions completely consistent throughout.
The duel begins with both fighters struggling to maintain balance as the ship tilts. They charge and exchange powerful sword strikes, with realistic blade impacts, recoil, footwork, slips, and recoveries. A hanging rope swings violently as the ship pitches, while barrels and loose debris slide naturally across the wet deck.
A huge wave crashes over the side, sweeping water across the deck and forcing both warriors sideways. One drops to a knee while the other uses his sword against the deck for temporary support. They recover and charge at each other for one final clash beneath a flash of lightning.
End with their blades locking as the ship rises on a massive wave, followed by a dramatic backward camera pull revealing the storm, ship, and enormous wave behind them. Cut to black on a thunderclap.
