Open Sesame! Witcher 3: Wild Hunt Quest

1. Go to the Borsodi auction house in Oxenfurt and ask for the owner.

Go to Oxenfurt and find an auction house. The guards will not want to let you in because you do not have an invitation to the auction but Vimme Vivaldi will appear and you will enter with him.

2. Go to the upper floor of the auction house.

When you go inside and you tell Vimme what brings you here, he will promise you that he will try to introduce you to Horst Borsodi. Then follow him to the top floor where the auction will take place. When you get there, he will tell you a little bit about other people taking part in the auction.

3. (Optional) Meet Vivaldi's friends. 0/3

You don't have to talk to any of these people, but when you do you can get some benefits.

4. Sit down when you're ready to take part in the auction. / Wait for the auction to start.

When you speak to all friends of Vimme or just sit down on the bench, the auction will start. You can choose not to take part in the auction, but if you decide to bid, you will be able to buy three items at the auction. Buy them all to unlock the "Shopaholic" achievement / trophy.

1. Count Romilly's figurine, a statuette of an eagle - Price: 300 crowns. If taken to any blacksmith or armorer, it can be dismantled into two pieces: Count Romilly's will and an Ornate key, starting the side quest - A Dark Legacy.
2. Starry Night Over the Pontar, landscape painted by Van Rogh - Price: 20 crowns / 60 crowns (if you have to outbid Vivaldi). You will receive a new treasure hunt quest - Avid Collector.
3. The Professor's spectacles - Price: 350 crowns.

After the first part of the auction is over Horst will show up and Vimme will introduce you to him. Whether you are nice to talk to him or not, when you mention the house of Maximillian Borsodi, he will become very nervous and will order his guards to throw you out of his auction house.

5. Defeat the guards.

When you go outside, two guards (33) will want to beat you before they give you back your weapons. Show them that you are better than them and beat them in a fistfight.

When you defeat them, you will be hooked by a stranger, who also wants to get into the vault and will offer you a deal. He will tell you to come to an herbalist's hut near Oxenfurt and there you will talk about the details.

6. Go to the herbalist's hut near Oxenfurt and give the password.

Upon arrival at the hut of the herbalist, you will notice three Fallen Knights (33) banging on the hut door. They will attack you as soon as they notice you. Get rid of them and the herbalist will let you in.

When you tell him that you need some yarrow extract, he will open the hatch leading to the basement where you will meet the stranger.

7. Talk to the stranger. / Return to the Stranger to discuss the details of the robbery.

The stranger will introduce you to his plan of getting into the vault and inform you that you will need a few partners to be able to execute it. He will tell you the options you have and you will receive three new quests.

8. Recruit the rest of the crew and prepare for the robbery. 0/3

You must now complete the following quests before you can continue:

• Open Sesame: The Safecracker - You must recruit the person who will open the safe. This could be Casimir who uses explosives or Quinto who will do it quietly.
• Open Sesame: Breaking and Entering - You need to recruit someone who will help you get to the tower. After all, it can only be Eveline.
• Open Sesame: Witcher Seasonings - You have to create a special elixir and convince the cook to add it to the soldier's food.

9. Go to the herbalist's hut to prepare the robbery.

Go back to the herbalist's hut where in the basement you will meet other members who will take part in the robbery. The Stranger will provide you with an action plan and set a start time for the operation.

10. Be at the gateway to the Borsodi Auction House around midnight.

Be at the gateway to the Borsodi auction house around midnight. After a while the others will join you and you will start to carry out your plan. Eveline will climb the tower and drop the rope which you will climb up.

As there was a guard in the tower that should not be there, the Stranger will want you to draw your sword and kill any further enemies. But you will refuse to do so and will take the wooden sword lying in the tower. Then you put on your masks and move on.

11. Get to the vault in the Auction House's basement. / Defeat Horst Borsodi's men. / (Optional) Fight off the Redanian soldiers' attack.

Go downstairs to the auction house, where you will come across a few workers who will immediately call the guards (33). The fight will begin. After a while Horst will enter the room. When he realizes what is happening he will start running away.

You will chase after him but he will manage to escape and lock inside the vault. One of his men will use the bell and after a while a group of soldiers will appear in front of the auction house. The stranger will grab a hostage and leave you to negotiate to gain some time, and the safecracker will go to work at the vault door. What happens next depends on who you recruited as a safecracker.

If you have recruited Casimir, even if you manage to gain time, the explosion will cause the guards to run inside and you will have to fight them.

If you have recruited Quinto, you will avoid fighting the guards if during negotiations you will choose:

Pull back from the auction house. > Bring us a wagon and horses. > Doesn't matter. Long as it rolls. > I'll set one free now. The rest later.

or

Pull back from the auction house. > Tell me a joke. > Actually kind of funny.

12. Go down into the vault. / (Optional) Defeat the monsters.

Eveline will leave you, she will squeeze through the chimney so you will go to the vault without her. Make your way downstairs towards the vault.

If you have recruited Quinto to open the vault, after passing through the door to the vault, the trap will activate and you will fall into the cave with four arachnomorphs (32). You will no longer use a wooden sword but your own swords. Once you kill them you will be able to return to the vault.

If you have recruited a Casimir to open the safe, you can easily enter the vault as the explosion most likely destroyed the trap mechanism.

13. Search the vault for Maximilian's House.

Go on and enter the final room of the vault. You will meet Horst and his two bodyguards there. Then you will know the real identity of the stranger, it is Ewald, Horst's brother, whom Horst banished from home.

Horst will try to bribe you and the safecracker to switch to his side. You must choose which brother you want to support. If it was Casimir who opened the vault, he will alweys choose Ewald's side and Quinto will always take the side of Horst. Then the fight will start.

14. (Optional) Defeat Horst Borsodi.

If you have not accepted Horst's offer then you will have to fight Horst, his bodyguards and Quinto if it was him who opened the vault. You won't kill him, but Ewald will.

After the fight is over, Ewald will not want to give you Maximilian's house because inside there is his father's will, which he needs. You can convince him to keep the documents and give you only the box and then you will part in peace. You can also fight with him.

If you tell him to keep the documents because you just need a box:

15. (Optional) Defeat Ewald Borsodi.

If you have accepted Horst's offer then you will have to fight Ewald and Casimir if it was him who opened the vault. You won't kill him, Horst will.

After the fight is over, Horst will not want to give you Maximilian's house because inside there is his father's will, which should not reach the hands of Olgierd. You can convince him to keep the documents and give you only the casket and then you will part in peace. You can also fight with him.

If you tell him keep the documents and you just take the box:

16. Get out of the auction house.

Go through the tunnel and use the lever to open the passage to the outside.

17. Take Maximilian Borsodi's House to Olgierd.

Go to an inn in Oxenfurt and talk to Olgierd. Of course he will be more pleased if you bring him a box with the contents. You can listen to his story about why he hates the Borsodis and then this quest will end.
