Barrel bomb

The Barrel bomb is created when putting a pot of quicklime and ground sulphur on a barrel of naphtha during the Regicide quest. After obtaining the Barrel bomb, a strip of cloth needs to be added to activate it. The bomb is then to be shot at King Tyras, killing him in a fiery inferno.

This is one of the heaviest objects in the game, weighing 32 kg. The other objects are the Barrel of coal-tar used to make the bomb in Regicide. However, the Barrel of naphtha is the heaviest item in the game, weighing 36 kg.
