STAGE 1 (0-3 seconds): Wide cinematic shot of the ARTEMIS mecha (Moonstrike Precision Frame) standing in a destroyed industrial zone at night under moonlight. It holds its large crescent rail bow in a ready position. The mecha slowly raises the bow and begins spinning it on a clear central axis, gradually increasing speed like a high-speed propeller.

STAGE 2 (3-6 seconds): The spinning crescent bow builds intense blue energy. Bright energy crackles and compresses at the center of the weapon as it spins faster. The mecha’s body stays stable while only the bow mechanism rotates at high speed. Strong energy glow and particle effects.

STAGE 3 (6-8 seconds): The bow reaches peak charge with bright blue-white energy concentrated in the center. The mecha stops the spin cleanly and immediately begins firing.

STAGE 4 (8-10 seconds): The ARTEMIS unleashes a rapid barrage of blue plasma bolts from the bow’s central mechanism in multiple directions. Bright muzzle flashes, energy trails, and recoil effects with each shot. Final wide shot showing the aftermath with residual energy glow on the weapon.

Key Improvements Made:
Issue in Original Attempts: Fix Applied. Unclear spinning motion. Clearly stated “spins on a clear central axis” + “only the bow mechanism rotates.” Weak energy build-up. Used staged charging language based on the reference sheet. Messy transition to firing. Clean stop of spin → then rapid barrage. Poor weapon fidelity. Referenced the Crescent Rail Bow design from your sheet.
