Supreme Slash, also known as Evil-breaking Slash, is a unique and highly distinctive technique that exists somewhere between Combat Skills and Magic.
Despite its impressive name, its essence is actually a method of channeling and using Positive Energy to attack.
Roland was interested in this technique because of its particular effectiveness against Undead Creatures.
His experiences in the Land of Mist had given him a deeper understanding of this world, making him especially wary of Spiritual Creatures like Ghosts.
If not for the potion given to him by Witch Vanessa, which protected against Negative Energy, he doubted he could have repeatedly escaped the encirclements of Spiritual Creatures unharmed with only the handful of Magic spells he knew.
Supreme Slash happened to address his greatest weakness.
Moreover, to learn Supreme Slash, one must first master the method of channeling Positive Energy.
