Cinematic dark-fantasy spell duel on a wild storm-lit beach at dusk — vast crashing surf, black volcanic sand, jagged sea-stacks, low heavy storm clouds split by distant lightning, sea spray and mist in volumetric haze, foam racing across wet sand. 35mm film grain, blockbuster grade: stormy slate-grey and bruised-violet sky, deep blacks, teal and gold spell-light accents. Two duellists: NERISSA, a tide-caller in flowing sea-green robes bound with rope and shell, soaked hair whipping, seen in three-quarter back-and-profile, face shadowed and lit only by her teal magic, never front-facing; and HALDOR, a storm-caller in a heavy weather-beaten coat and iron bracers, face turned to silhouette against the lightning, channelling crackling gold energy through both hands. Keep faces obscured throughout. [0-3s] Static wide, locked tripod. The two face off on the open sand as a wave retreats between them, robes and coat snapping in the gale. Only surf, spray and fabric move. [3-6s] Low over-the-shoulder behind Nerissa. She sweeps both arms up; a towering wall of seawater rises off the surf and curls forward toward Haldor. Slow push-in. [6-9s] Reverse on Haldor. He throws his hands skyward; a fork of gold lightning cracks down and detonates the water wall into an exploding curtain of steam and spray. He strides forward through it. Whip pan tracking him. [9-13s] The two collide at the waterline — surging water and crackling lightning grinding at a white point between them, foam and electric sparks spiralling, sand blasting outward in a ring. Slow orbit through the spray. [13-15s] Nerissa drops and slams a fist to the sand; a massive wave rears and crashes down as Haldor's lightning splits the sky — both forces detonate together, hurling both figures apart in an explosion of water, light and spray. Hard cut to black. Separate subject and camera motion. Only the duellists, water, lightning and spray move fast; framing stays controlled. Audio: roaring surf and howling sea-wind throughout, tense low drone rising to a percussive climax; rushing water swells, sharp thunderclap and electric crackle, water-to-steam hiss, a thunderous mid-clash with deep sub-bass, a final wave-crash and lightning detonation snapping to ringing silence on the cut. Hits land on the thunder. sharp clarity, natural colors, stable picture, no blur, no ghosting, no flickering, avoid identity drift, avoid bent limbs, only two characters visible, no duplicate figures.
