Karna gives away his armour

Indradev asks Karna to donate his Kavach and Kundal to him, or not participate in the war. Karna obeys him. Arjun tells Indradev that he will kill Karna anyway, but to kill a warrior deprived of his weapons may cast a doubt on his own abilities. So, Indradev blesses Karna with a divine weapon.
