This skill is mainly used by protective Knights to indirectly protect the Knight's allies in an area chaining, especially from Sultar's Terror, since the Knight not disabled by Sultar's Terror can prevent the rushing enemy warriors to cast areas like Lightning Strike or Thunder Strike. It is also used at fort and castles doors for the same reason.
