While using Shield Wall, if Shield Bash is researched, when an opponent's unit comes into range of the spear, the spear will throw out its shield, stunning the enemy for several seconds. Shield Bash is then on a 6 second cooldown until it is next used. It is automatically used when an opponent comes near the spearton (previously it had to be used manually until a new patch which changed this).
