A class is the primary adventuring style of a player character which determines the type of weapons and armor it can use, as well as what abilities, powers, skills, and spells it will gain throughout its adventures.
Be aware that the choice of which class to play is constrained by the choice of race; each race has a different group of available classes to choose from.
Each class has a unique talent tree. As a character progresses, they can specialize their skills by assigning class talent points for their class. There are 10 classes for you to pick from.
