So I'm currently playing a dual wield character, and I'm loving the finishing moves that I can do, but Is there some trick to making them happen? I mean I was just stuck at a part in this one dungeon, and I couldn't get past one of the boss - type mobs because every single time, he would always impale me with his freaking greatsword, and I mean every time, no matter what my health was at. So is there any trick to doing these? I guess I just don't fully understand the combat system yet
