Prahasta

Enraged by the slaughter of his invisible ambushers, Ravana leads his full army against the monkeys, arranging them in the fearsome ushanas battle formation. Rama counters with a formation recommended by Brihaspati, and the two armies collide in a battle that shakes the three worlds.

Prahasta rushes at Vibhishana and strikes him with a mace, but Vibhishana does not stagger — he stands firm like the Himalayas. Then Vibhishana invokes a mantra on a gigantic spear and flings it at Prahasta's head with the speed of the vajra, slicing it off. Prahasta falls like a tree struck by wind, and Dhumraksha charges forward in response.

Ravana learns that Kumbhakarna, Prahasta, and Dhumraksha have been killed in battle. He summons his son Indrajit and commands him to kill Rama, Sugriva, and Lakshmana, reminding him of his past victory over Indra himself. Indrajit agrees, dons his armour, mounts his chariot, and proceeds to the battlefield.
