According to Mahabharata, the characters Ashwatthama and Arjun used this weapon.

The weapon manifests with the four heads of Lord Brahma as its tip. The characters Sage Agnivesa, Drona, Arjuna,Karna and Ashwatthama possessed the knowledge to invoke this weapon.[1] This weapon can be invoked into any object, even to a blade of grass.

In Mahabharata, it is explained that when this weapon is invoked, "It blazes up with terrible flames within a huge sphere of fire. Numerous peals of thunder were heard, thousands of meteors fell and all living creatures became terrified with great dread. The entire sky seemed to be filled with noise and assumed a terrible aspect with flames of fire. The whole earth with her mountains and waters and trees trembled." When it strikes an area it will cause complete destruction and nothing will ever grow, not even a blade of grass for the next 12 years. It will not rain for 12 years in that area and everything including metal and earth becomes poisoned.[2]
