I had the chance in a recent fight for a Primaris Psycher to kill an Avatar in HtH (force weapon+psychic test) but when we checked to see if the Avatar was immune to such instant death we couldn't find an obvious answer. Fluff wise, I ended up agreeing that the Avatar is a form of Deamon and by those rules couldn't be killed that easily but by the actual Codex: Eldar rules....it was a little fuzzy. Anyone know if this has actually been clairified anywhere?
