Draug was kinda hard, but in an odd way. When I could flank him, he went down easily, killed him in 3 "flanks". But the problem was getting behind him. Died a few times trying to do it. When I killed him, my life was basically down to a half a centimetre, mainly due to his sword swipes. Second i see him twister-ing I threw up Quen, but I don't like using Quen unless necessary because vigor regen stops, and I use a heavy magic build. (Igni, Aard, Axii mostly, sometimes Yrden.)
Axii's awesome for groups of stuff like shielded knights/mercs, or tough things in general. Much better than it was in TW1. Conversely, Igni is not the win button it used to be, but still alright.
