Voidfiend in duels

Now that Azerite Snake is a thing and we see how stealing health works with it… bypasses armor and lowers maximum health, shouldn’t Voidfiend from the priest power in duels also do the same? The abilities are worded the same other than one gives it to the hero and the other keeps it for itself.

Either it needs to be fixed or the wording needs to be changed to “do one damage to enemy hero.” Right now it doesn’t lower maximum health and it doesn’t even bypass armor.
