Every class has 3 skill lines which further define their play style. You can take a look at full skill lines for each of the class in our guides: Nightblade, Templar, Dragonknight, Sorcerer.
The 4 basic ones are defined by your choice of class and race: every class has three distinct skill lines that can’t be otherwise obtained, and every race has its own set of racial bonuses.
Your character has access to many different skill lines. Skill lines are essentially skill trees as you’d expect to see in an RPG game: as your character progresses through the game you gain skill points which are allocated to particular skills to be able to use them or improve their effectiveness. We briefly touched on the topic of skill lines in our article about character progression and class guides, but it’s time to explain the system in more detail.
