A dagger forged from the essence of the ocean's abyss, with a dark blade veined with glowing aqua currents. The hilt is made of black coral, adorned with sharp spines and shimmering sea glass. When it strikes, it drains life force from its target, leaving a trail of misty bubbles. The weapon hums softly with the sound of distant waves. The background shows a submerged temple with glowing ruins and drifting seaweed. #clay#
