Cacophony Blade

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

Description
The cruel blade of this two-handed sword is a massive, black stone chunk, studded with semi-sentient spikes across its upper edge. The spikes shiver with hunger, and when you touch one of the spikes with your finger it wriggles eagerly, as if trying to detach and dig into your flesh. When the spikes hit a target just the right way, a number of them fly off and burrow into anyone within range. Whenever you use the weapon this way, a demonic sounding screeching fills your ears.
