When Nameless Sword's Charged Skill Vagrant Sword is charged while you are out of combat, while the Qi shield is active, or within 5s of unleashing Shadow Step's sword energy or multiple sword energy attacks, it unleashes additional sword energy attacks upon charging to the second stage, consuming extra Endurance to increase the sword energy's damage; each point of Endurance consumed increases damage by 1.5%, up to 30%. The multiple sword energy attacks will not cause Abrasion when hitting Exhausted units. If the target is an Exhausted non-player unit, the third sword energy attack is guaranteed to be an Affinity hit. Unleashing multiple sword energy attacks triggers Qi Surge: immediately restore 20 Endurance; within 5s, you can unleash multiple sword energy attacks again without charging. Qi Surge starts with a 20-second trigger interval, which is reduced by 1 second the first time each sword energy attack hits a boss unit (up to a maximum reduction of 8s).
