Way of the Assassin is a side quest in Dragon Age: Inquisition. It is one of three potential quests which a rogue Inquisitor can complete to obtain a specialization. Craft a proper knife, study the methods required to wield it, and Heir will reveal the secrets of the Assassin specialization. Kill guild leaders for their tokens at the East Side Hills, the Flats, and the Black Fens in Crestwood. Readings can be found among the belongings of followers who share this discipline. Or, if unavailable, among the wares of the book merchant in Val Royeaux.
