Vasavi Shakti: O Sun, Abide to Death (日輪よ、死に随え, Nichirin yo, Shi ni Shitagae (Vasavi Shakuti)?) is a spear of light that can even kill gods. It is a spear of mortality made out of lightning that is manifested by converting his golden armor, Kavacha and Kundala, due to Indra snatching it away in the legend and then rewarding Karna's noble posture with the spear. It can only be used once, exchanging tremendous defensive power to equip a spear with a powerful "anti-god" performance.
Although Karna gives his armor to Jinako Karigiri in Fate/Extra CCC, he still manages to utilize the ability without what actually forms it, but he is left close to death after his battle with Hakuno Kishinami's Servant due to that.
