Specializations grant you access to additional talent trees that you are able to spend your talent points on. You will earn class specializations at levels 7 and 14. There are a total of 3 specializations for each class and they unlock their own special abilities. Unlike in Dragon Age: Origins, there are no specializations for your companion characters. Also, you do not need to learn these specializations from specific sources as they are simply given to you. In order for the achievement to unlock, you will need to place at least one talent point into two of these specializations.
