Hi there,
I am new to the forum, but not new to playing DD and the BD Demo.
In DD, you have the "special move" ability as a fighter,i dont think a lot of people EVER used it, it wasnt that powerful. In BD, i found this to be of GREAT help when killing guards. It makes it much more difficult for you to get hit by them, and the damage you do to them is also increased.
The first time i tried to kill the guards, it took quite a bit of getting beaten and potions, i then assigned my first skill as my special move (on both caracters), and killed just about any guard or monster i encountered with relative ease.
Hope this would help the people finding some guards difficult.
