Obliteration Rounds: The World-Shaker Slugs

These massive 12.7 x 55mm cartridges are topped with flat, blunted slugs of matte-black star-iron. The casings are forged from polished adamantine and inscribed with microscopic silver runes of inertia. When held, the rounds feel unnaturally heavy, as if they are pulling toward the ground with the weight of a mountain. A faint, low-frequency hum emanates from the cartridges, vibrating the air around them.
