Hits to the head are said to do critical damage (i.e. more), and I’ve seen the figure of 50% extra damage put about (and that seems to accord with what I’ve observed in battle logs). But one of the special attributes listed for axes is that they do an additional 50% of damage on a hit to the head. So how does that differ from the 50% increase that’s done with any other weapon? Is the 50% bonus from axes additional atop the 50% bonus that’s done with any weapon (so that it should really be referred to as a 75% bonus)? Or what?
