The Blood Cannon and the cauldron of boiling blood that fuels it.
The Blood Cannon is a Daemon Weapon of Chaos that is used as the main weapon of the Cauldron of Blood Daemon Engine. The weapon takes the form of a massive Flamer made of Warp-forged black iron and brass wholly dedicated to the service of the Blood God Khorne.
The weapon is fueled by a large cauldron located on top of the vehicle which is used to boil the blood of slain foes with daemonic Warpfire.
The boiling blood is as hot as bubbling lava and capable of turning both infantry and vehicles into piles of slag once fired from the nozzle located on the front of the vehicle.
It is unknown if the Blood Cannon is used by any other Chaos vehicles, daemonic in origin or otherwise.
