I bought a 21 stone broadsword recently and at first I was getting 1/3/4 roundtimes (feint/draw/slice) when I had sure footing at min cast up. Out of the blue (or so it seemed to me) I started getting 3/4/6, with any power of sure footing I cast. I have 20 strength and 20 agility. Anyone ever have a similar experience that can help?
