Specializations are sub-class choices that further define and customize characters in the Dragon Age series. They open access to new talents based upon the character's base class (Warrior, Mage or Rogue).
In Dragon Age: Origins, specializations must be unlocked. Each companion has one specialization when recruited, with one slot free for a second specialization. Their starting specialization can be taught to the Warden and their companions.
In Dragon Age II, specialization points are granted at every seventh level (7, 14, 21). Each companion has one exclusive specialization, which cannot be passed on to others. Companions are unable to learn an extra specialization.
