Saw this on Indra's page under abilities.

"Indra's most powerful weapon is the Vajra a club with a ribbed spherical head,that is able to shot incredible power bolts of lightning that can easily destroy anything. Indra used the weapon to slay countless Asuras and the Evil Dragon King, Vritra. Indra also possessd the magical dart called the Vasavi Shakti which is a sure kill weapon able to kill almost anything this was demonstrated when Karna borrowed the dart and killed Ghatotkacha in one shot."

Though this is probabily from the myth does it apply to the DxD universe?
