NCSoft has announced that the Unchained update is now live on Blade & Soul servers. The update brings the new Warlock class into the game as well as Naryu Labyrinth and Mushin's Tower, Floor 8 in addition to various bug fixes and feature enhancements.
The Warlock is Blade & Soul’s second dedicated ranged class with great power but considerable fragility. Many of their powerful abilities have significant casting times and long cooldowns, requiring one of two strategies to be employed: keep enemies at bay or incapacitated long enough to be able to cast the high damage abilities again, or reduce cooldown times through expert timing of other abilities.
