The next morning, Krishna sends Kunti to request Karna join the Pandavas or swear not to kill them. Karna blames Kunti, the mother who abandoned him, for the destruction, but swears not to kill anyone except Arjuna, on the condition that Kunti have five sons if either he or Arjuna dies. The next day on the battlefield, Karna tries to kill Arjuna, who is protected by Lord Krishna. Krishna sends Indra in the form of a Brahim to trick Karna into giving up the divine breastplate which protects him. Karna does so, even knowing the truth, and Indra gifts him a powerful weapon which can only be used once. While wishing to use it against Arjuna, Karna is forced to use it when the camp is attacked at night.
