Earth-Shaker Rounds

These massive, 40mm-caliber shells are carved from midnight-black obsidian and inscribed with glowing violet arcane geometry. The tips are capped with a swirling nucleus of concentrated gravitational energy. When held, the rounds hum with a low-frequency vibration that makes nearby dust dance in geometric patterns, and they possess an unnaturally high density that causes them to pull slightly toward the planet's core.
