We all know that Vibhishana was a Brahmin-Daitya/Brahmin-Rakshasa and was an ardent follower of Lord Rama. But I think he didn't kill even a single person in the Rama-Ravana war. So, in my view, he shouldn't be called an asura as he did not have any asura-like qualities.

But does Ramayana talk about Vibhishana being a strong warrior or if he wielded any weapons?
