Void-Piercer 12.7mm Shell

A heavy 12.7 x 55mm cartridge with a casing of matte-black carbon steel and a projectile carved from a single dense shard of pressurized obsidian and cold iron. Translucent violet ley-lines crawl across the surface of the bullet, pulsing like a slow heartbeat. When handled, it feels unnaturally heavy and seems to dampen the sound of footsteps and nearby whispers.
