Skill duration: random. Type of skill : neutral skill. Affecting stats: Str/Dex. It uses no endurance points. Those fighters who practice a defensive style of fighting do not limit themselves to defensive tactics. Once they possess the ability to parry attacks, they gain the ability to counterattack. By throwing their opponents attack to the side, they are able to complete the move by hitting their opponent, who is still in mid-thrust. Fighting someone who has mastered this technique can be frustrating, besides deadly.
