Are the character taunts triggered by a specific series of events, or are they random? It seems like when I get several critical hits, or many kills within a quick period of time my character will have an audio taunt. But I was wondering what exactly triggers them.
Taunts trigger from getting the Massive Blow award (6+ kills in the span of one second) and from leveling up. (Two separate audio groups; level up taunts will not play after massive blows and vice versa).
Massacre, Destruction, and Survival do not trigger verbal taunts.
Finally, Followers will taunt both upon spotting and defeating a rare, unique, or champion pack. (There, a worthy foe! // Now THAT was a fight)
Taunts are class specific, but I do not know whether or not they change based on gender as well.
