Specializations
Specializations are sub-class choices that further define and customize characters in Dragon Age. Specialization options are linked to the character's base class—warrior, rogue, or mage—and each character can have up to two specializations. Specializations are achieved by learning through a trainer (a person who can teach it) or a plot event.
Note: If you see that many characters have the same specialization, PLEASE choose a different one. After all, the point of specializations are to customize your character.
