Chantry Historian is an achievement in Dragon Age II. It is obtained when you find four of Brother Genitivi's written papers, across all three acts of the game. To gain the achievement, you must find them in a single game. Though relatively easy to obtain, the third one is very tricky.
(Note): If you want to keep count if you have the Chapters go to the journal and select lore.
- The History of the Chantry: Chapter 1: Discovered in the Chantry during Act 1. It is on a table on the right side of the room upstairs. (Where you fight the Templars during Anders personal quest.)
- The History of the Chantry: Chapter 2: Located on the podium where the Grand Cleric is standing, during Act 2.
- The History of the Chantry: Chapter 3: Located on the same podium during the quest Following the Qun. This one is insanely difficult, as you can only get it between cut scenes of the fight with Mother Patrice's fanatics in the Chantry. If you do not get it during this time, you will lose it. The best way to get it is to remain at the podium during the fight, and stay facing the podium as much as possible. After the fight, you have a 3-5 second window to grab it. (Note: To avoid missing this codex entry, pick it up during the heat of battle. Bring up the the radial wheel while fighting to pause the action; you can then target the podium and select the codex entry. Your character will pick up the entry even though there are enemies around.)
- The History of the Chantry: Chapter 4: Located in the Chantry during Act 3. This time it is on the table in the left room upstairs. You must obtain it before certain events take place in Act 3, or you will lose it for good.
Once you obtain all four of the chapters, you will earn the achievement "Chantry Historian".
