Classes can be thought of as the basic foundation for what your character can do. There are four basic class archetypes: hunter, scholar, sneak, and warrior. From these four archetypes stem every class. There are basic classes such as thieves and fighters, and advanced classes such as druids and spies. Each character will choose an archetype and then become the starting class associated with that archetype.
