We plan to release with 5 skill classes, each containing several skill trees. Additional skill classes will be introduced through downloadable add-ons. Players will be able to combine any two skill classes to explore powerful synergies that exist between the skill trees of different classes and experience the varying gameplay styles of each class build. It will be impossible to max out all the skills from two classes, so there will be plenty of experimentation to find the best way to allocate your points. Don't worry though, if you aren't satisfied with your build, you will be able to spend money to reclaim spent skill points.
