Deciphering the Most Venomous Weapon of Ancient Times - Blood Dropper

The blood dropper is a throwing weapon. Its exterior is a long iron chain connected to a round hat-like metal object, which can be placed over the enemy's head. The edge of the metal hat has many long knife-like teeth, which will cut off the enemy's neck when the blood dropper is placed over their head. While in flight, the blood dropper also continuously emits a shocking and terrifying "whooshing" sound.
