7.Narayanastra.

One of the three Great weapons of Mass destruction, others being Brahmastra, Pasupatasta, Narayanstra would destroy anything and the only way to escape its wrath is to drop all the weapons and prostrate before it.

Aswathama used it unsuccessfully and under instructions from Krishna Arjuna had it withdrawn.

8.Brahmastra-Though not used in the Mahabharata war, it is one of the Great weapons.

Please read my post on this.

9.Pasupathstra.

Though this was obtained by Arjuna from Lord Shiva, Karna from Parasurama, Arjuna did not have the occasion to use this and Karna could not as he

was cursed to forget the launching Mantra, by Parasurama.

10.Aindra astra:
Presiding Deity: Indra, the god of weather
Weapon’s Effect: Would bring about a shower of arrows from the sky.

Used by both the sides.
