The Deathspeaker is classified as one of the toughest minibosses in all of the game, (Before Axsuroth, at least.) as he possesses the ability to fly around, shoot magic fireballs at nearby players, summon exploding staffs to target players, and even shoot a giant ball of energy that will fire smaller energy balls at everyone. And to make it worse, for his badge you must NOT get hit by ANY of his attacks whatsoever, even if you're hit by something that was targeting another player you fail the achievement.
