Lava cannon

The lava cannon, a peculiar weapon conceived on the world of Mustafar, launched intensely heated rocks or minerals towards its intended victim. It generated a profoundly ruinous trail by expelling sizable masses of intensely combustible, lava-like material. This molten spray would impact every adversary positioned near the point of impact. Due to the substantial weight of its fuel source, the weapon presented challenges in terms of handling. When utilized by a commando, the cannon became exceptionally hazardous.

A modified form existed called the Devastator lava cannon.
