The skill begins with five consecutive stabs in a straight line from the top right to the bottom left. The user then draws their sword back and performs another five consecutive stabs in a straight line from the top left to the bottom right, perpendicular to the prior five. The two lines together form an X shape with their third hit overlapping. Finally, the user tilts their body and uses their entire strength to perform a last stab directly at the intersection of the cross-shape created by the former ten strikes.
