Earthshaker

This heavy projectile is forged from a core of hyper-compressed obsidian and heart-iron, shimmering with a dull, rhythmic amber glow. It weighs significantly more than standard ammunition and vibrates with a low-frequency hum that can be felt in the marrow of one's bones. Tectonic runes are etched into the surface, leaking a faint trail of crystalline dust when handled.
