Forged from the tooth of a subterranean behemoth, this dagger is the brutal signature weapon of the "Maw Raiders" tunnel assault unit. Its single, piercing hole in the blade channels seismic energy to create a concussive blast on impact, while the ribbed, stone-like handle ensures a secure grip even in the dustiest tunnels.

The weapon is said to roar with the heartbeat of the earth, and each strike can collapse cave-ins to bury enemies. However, its seismic core is unstable; overuse will trigger localized earthquakes, risking the user's own safety, so operatives must wield it with precise, controlled thrusts.
