I will definitely try out something similar if I start a third playthrough. Currently in my Honour mode run I feel a bit hardpressed, especially because I did not play Act 3 before in normal modes. It's also surely better to play a build from the beginning, to get accustomed to it.
However there is hardly room for playing something other than half elf for me. I just don't like the other faces and fell in love with one of the half elf options. Is there lore for a half elf female to be something like such a lightly armored sword dancer?
Second question, how/wherefrom do the enemies get the damage when they miss you?
