we know dragons use the voice but what will voice battles against druagers and possibly the grey beards be like

NOTE : dragons vs dovakhin voice battles = smart
druagers vs dovakhin voice battles = smart
grey beards vs dovakhin voice battles = possibly not smart im intimidated by them

I don't think mobs like draughers or however you spell it can use shouts. If I'm not mistaken only dragons and dragonborn people can use shouts. I don't know though as I've never played the game.

Yeah, I don't think Draugr can use The Voice, but Dragon Priests can I think... I know they said dragons, greybeards and dovahkiin are not the only ones who can use the voice(I'm pretty sure).

todd said they indeed can

Would you happen to recall the particular interview or article where that was said? You've got me curious now.

were you watching epicmealtime when you wrote this?

and arnt all the greybeards gone, that is why dovahkiin is so special
