  3. During the next cut scene, select “I’ll handle the guard” and then “Search for another entrance” to following that. Afterwards, choose “You’re too kind” and then “Does he do tricks?”.

  5. Afterwards, select “Then we find the servant” and return to the hedge entrance that lead to Leopold’s cage. Interact with the elf servant to the right of the hedge entrance and respond with “It’s kind of you to offer”, then select “We won’t get you in trouble” to activate a cut scene.

The Chateau

  1. Select “Are you alright” and then “I agree” when speaking with Tallis. You’ll be in stealth mode after the cut scene, so creep around the corner ahead and move behind the next guard.
  2. The guards will be unable to see you within shadows or dark corners and they will be unable to hear you if the character is moved around slowly enough. Their area of perception is represented as a pulsating wave of red light and they will immediately call for support if you travel within this zone.
  3. Use your distraction ability to pull up a targeting point of view, then move the circular cursor onto an area of the ground that’s to the right of the guard. Hit the action button to draw the enemy’s attention to the right, giving you the opportunity to head left.
  4. Move into the next hallway before the guard turns back around, then make your way forward and approach the “shadows” icon on the left.Once your character is in this shadows area, he will suddenly appear to you slightly-lit for the purposes of safely managing his movement.
  5. Make your way forward within the darkness along the wall until the path is blocked, then wait for the guards to walk past you down the hall and make a right.
  6. Move through the next door ahead on your left, then collect the items from the chest and exit the room. Make a left to continue along the corridor and earn the ability to incapacitate as you get closer to the guard ahead.
  7. Enter the distraction point of view and aim the circle on the area of floor behind the guard, then approach him once his back is turned. Move in as close as you can to the enemy without making contact, then execute your incapacitation ability to knock him out.
  8. Pick up the key and climb the stairs behind you to reach the floor above, then unlock the door ahead to move into the outside area. Staying in the shadows, make your way left to creep up the next set of steps.
  9. Move left around the corner at the top of the steps and make another left into the area lined with columns. Use your distraction ability to lure the guards over to one side of the room, then continue forward at a safe distance from them or use incapacitation if they get in your way.
  10. There is a treasure chest against the left wall as you move through the area with columns. If you can reach it without being spotted, the rewards will be treasure and a “Skepticism amulet”.
  11. Incapacitate the guard watching over the steps ahead, then make sure the other enemies are distracted before moving down them. Quickly enter the door in the corner, then move forward across the balcony to exit into the next room ahead.
  12. Exit the room, then ignore the door on your right and continue forward. Distract the guard ahead, then turn left when you reach the rug and move into the hallway in front of you.
  13. Follow the hallway around and incapacitate the next guard you encounter, then continue down the corridor to reach another rug and enter the room to the right of it. Collect the treasure and balcony key from the chests, then exit the room when the coast is clear and move forward along the rug.
  14. When you reach the next balcony area, collect the treasure to the left and turn around. Creep forward to the opposite side of the room and turn left at the wall, then move through the door ahead and enter the shadows to stay hidden from unseen patrols.
  15. Make your way towards the door that you ignored when first reaching this balcony area, then unlock it to enter the next room and move forward across the balcony.

  17. Make a right into the next area and move downstairs, then exit through the only door to reach the outside. Climb up the nearby steps and stick to the right side because it’s darker, then incapacitate the enemy hiding in the shadowy corner at the top and turn left.
  18. Use a distraction to lure the patrolling enemies over to the railing, then creep forward to pass behind them and use another distraction on the guard past the lamplight. Move forward through the light and turn left, then incapacitate the guard captain by the desk to pick up supplies and a balcony key.
  19. Head back the way you came and incapacitate the lone guard from before, then move past him to the railing and open the large chest. Use distractions on the two other guards from earlier, then enter the door on the right after passing back through the lamplight.
  20. Move down the steps and around the corner, then open the chests against the wall as you make your way across the hallway. Continue forward to pass by Tallis and activate a cut scene.
  21. Afterwards, switch characters to take control of Tallis and move her onto one of the raised tiles at the end of the nearby rug. Switch back to Hawke and move him onto the other raised tile, then climb the steps after the bars are raised to exit the cage.

  2. A few more cut scenes will play, then you will be freed from the jail cell and have full control of the characters again. Level up the abilities, wardrobe and weaponry of whatever characters you can before continuing the quest.
  3. Turn around and approach the doorway behind you to return to the Vault. Activate the white apparatus and open the rightmost white door, then activate the black apparatus and move through the previous door you opened.

I need help on the doors


On October 13, 2011 at 7:57 am

A little help with the Vault, please.


On October 13, 2011 at 1:44 pm

For some reason I can only open one chest in the vault and also the last gate will not open


On October 13, 2011 at 7:50 pm

I am also unable to get the last gate to open. Cannot go back through the crack in the wall, so now I’m stuck…can someone help?


On October 15, 2011 at 1:03 pm

Vault seems bugged as hell. I can only open one chest and pick up the pirate medallion- left hand chest is unopenable and can’t get the feather (have the first one from outside).
It seems as if I can either open the main gates for the vault door or open gates to get to the chest (tried in different saves), but once I’ve got the chest I can’t get the main gates open…


On October 15, 2011 at 10:40 pm

okay, i was caught locked in the dungeon room, escaped found myself in big room with nice firepit, unlocked some stupid puzzles all except for this big one made out of tiles. !@#$%^&* IT!


On October 16, 2011 at 6:19 am

Spoiler ahead…

The gate room is not bugged at all. Getting the second chest is another puzzle. After u get the first chest, make one character stand on the stone near the chest, and the other character stand on the stone near the first chest. This will open the second chest as well as the Main gate. (+600xp)


On October 16, 2011 at 4:18 pm

Damnit, how did I not get that?!
Cool, thanks for help. I went on and completed the DLC -looks like I’ll be replaying the last 3 hours of it now!


On October 16, 2011 at 5:35 pm

You are missing the third puzzle in the vault. This is the one I am stuck on.


On October 17, 2011 at 8:18 am

@dani Go to youtube for the video. It’s a pain in the butt to find the pattern unless you are ‘A Beautiful Mind’ savant

On January 17, 2012 at 6:34 pm

in the mark of the assasin dlc how do i solve the portrait puzzle


On October 1, 2012 at 10:19 am

This DLC is wicked.. I loved it! I save right before I start the add on and then I go back and re-do the quest with each of my ppl.. much more fun that way.. yeah I’m OCD with doing all the side


On February 21, 2013 at 5:20 pm

So you go through the entire DLC and the opponents are REALLY stingy on the potions. You can’t buy any or make any during the course of play, so by the time you reach the Boss at the end you’re almost out even if you hardly use any. This makes the battle nearly impossible to win.

Then if you do eventually win, the game leaves you stranded on the final scene with no way back to the main game!

What a smoldering, festering, putrid piece of crap! Whoever coded this needs to be eaten by an alpha Wyvern!


On April 29, 2013 at 1:25 pm

flip puzzle makes no sense


On November 16, 2013 at 6:45 pm

I’ve been having trouble with the Mark of the assassin dlc for Dragon age 2.
At the boss fight – where you fight Prosper and the Wyvern – the wyvern are supposed to switch place with Prosper, so you fight the wyvern instead of Prosper.
The problem is, the wyvern never jumps down from the wall. Prosper appears next to the wyvern and starts shooting me like he is supposed to but the wyvern doesn’t come down.
You can see a red circle on the ground where the wyvern are supposed to be, but you cant attack him.
I tried reloading another save and also tried playing on different difficulties, but nothing helped. I looked for patches but didn’t find one and tried to google but found no answers.
I have bought the game, so there shouldn’t be a problem.
I read that after you finish the dlc you see a cutscene where Hawke is back at the estate in Kirkwall. The thing is I don’t live in the estate with this character, since I just created a new character to play the dlc. That might be the problem, but I just want to make sure it is.
And if it matters, I brought Fenris and Anders with me, and I’m playing as a female mage.

Thank you, Viralsac!
