The Blackcliff Agate is a visually striking catalyst with a dark, metallic base adorned with crimson gemstones that glow faintly, suggesting a latent power. Its design features sharp, angular edges with intricate engravings that depict ancient runes, giving it a mysterious and arcane appearance. The weapon's surface is polished to a high sheen, contrasting with the rough, textured grip wrapped in dark leather for secure handling.
