The Du Lac Sign



This quest starts after you are taken captive by Duke Prosper, after your dialog with Tallis and your subsequent escape you have a choice of heading straight up into the vault room or making your way through the dungeons and then up into the vault room I usually take the later route as it gives you more xp.

After a short cut scene in the libary with Prosper and a battle you can head down into the vault room proper after opening the door to the vault in the libary, there will be a book on the floor clicking it will start a cut scene with Avaline where she will read the contents of the book and gives you the next part of the quest.

After you are finished robbing Duke Prosper, head back down to the dungeons via the door in the vault this door will take you near where you need to be. If you are a rouge or if you havent had Tallis or one of the other rouges in the party (Varric, Isabela, or Sebastian) unlock all the cells, do so now.

The second cell on the left is were you want to be there will be a gold arrow pointing to the floor click on it and it will start another short cut scene where Avaline finds a black vial and smashes it.

If you remember from the first game after you find any of the black vials it unleashed a reverent and a bunch of zombies no change here, killing the lot starts another cut scene with Avaline talk to her and that ends the quest for the time being, leaving a lot of questions unanswered for everyone involved
