Thunder Cannon

 is a Ranged Heavy Artifact weapon in Torment: Tides of Numenera.

Description
Though this bulky metal device was not intended as a weapon, a handle was added at some time in the past, allowing it to be wielded as one. When someone takes hold of the handle, a low buzz emanates from the device. The sound intensifies as the weapon prepares to fire, building to a crescendo and discharging with a thunderous roar. The cannon's 'projectiles' are blasts of sonic vibrations, capable of striking a target with deadly force.
