Lunging backwards the masked opponent avoided both the stab and the stalactites as the fell. After tht maneuver was done he rushed towards the woman and once he reached her shield he dropped into a crouch. From the woman's point of view behind the tower shield it would appear as though he just vanished. As he dropped his left hand brought the knife around what would to her be the left edge of the tower shield. Using the knife as a hook he pulled the shield out towards him opening a hole in her defense which his shortsword shot into.
