In your opinion, which hero has the most charisma in the campaign?

To be honest, I summoned the Avatar of Death only once during the entire campaign, in the very first battle against the wizard, because I had no other choice. I don't see it being of significant benefit. However, his Charisma was definitely noticeable, especially how he made 4 necromancers die without any hesitation, or rather 5, of course, Ash always turns everything to his advantage, but still... He could have learned Astral Gate.
