Blade & Soul Expansion Secret of the Stratus to Revamp the Skill System
The plot of Act 7: The Search, invites you to hunt down the Hongmoon School's youngest and most valuable protege. In your adventure you can also rely on some new allies: Chol Mugo, Admiral of the Blackram South Fleet, and Ku Yang, the new Blade Master representative.
The revamped skill system removes skill points and the skill trees for each ability, and instead offers "a more intuitive and simpler solution that maintains build customization and fluidity." The image below shows how the new system looks like.
The new expansion also includes a lot of new features. You can see the details at the official site.
