A throwable sonic device that produces a focused acoustic blast exceeding 190 decibels within a 10-meter radius. The Banshee generates its acoustic output through rapid piezoelectric expansion of a crystalline core, converting stored electrical energy into a single devastating sound pulse that ruptures eardrums, fractures sinus cavities, and can cause fatal pulmonary hemorrhage in targets within 3 meters.

Fenris Ballistics designed the Banshee as an area-denial weapon that bridges the gap between flashbang grenades and lethal fragmentation. The device is activated by a standard grenade fuze with a 2-second delay, and the acoustic pulse propagates omnidirectionally from the crystalline core. The sound wave reflects off hard surfaces in enclosed spaces, creating interference patterns that amplify the effect in corridors and rooms.

Unlike conventional grenades, the Banshee produces no fragmentation and leaves no blast damage to structures. The only evidence of its use is organic — ruptured eardrums, hemorrhaged lungs, and the shattered crystalline core of the device itself.
