Open Sesame! is a main quest in the Hearts of Stone expansion. The task of infiltrating the Borsodis' Auction House is one of three difficult requests made by Olgierd von Everec.

Summary Edit

Upon reaching the Borsodi Auction House, you’ll be confronted by two guards who inform you no one is admitted without an invitation. Thankfully, before the situation can get too ugly, Vimme Vivaldi (an old acquaintance of Geralt’s whom you may recognize from the Vivaldi Bank in Novigrad) steps in and adds you as his +1. Once inside, you’ll converse for a moment about life, the universe, and nothing in particular until Vimme decides to head upstairs. Upon reaching the auction floor, he offers to introduce you to some of his… friends.

The Art dealer Edit

The Art dealer challenges your knowledge of a renowned painter’s work, assuming that you’re as cultured as your vertically-challenged associate. Prove him wrong by choosing the correct painting - the Portrait of a Merchant.

For pointing out the correct piece, the dealer will give you a tip: bid on the painting by the up-and-coming artist called Van Rough, and sell it at a much higher price to a fan and collector in Novigrad. Be cautious, though - if you share this information with Vimme, he’ll attempt to outbid you for the painting, and you’ll end up paying three times the original asking price for it.

The Countess Edit

This aging widow is a collector of rare and valuable Witcher gear, thanks largely to an infatuation she developed for the profession after a tryst with a Witcher in her youth.


Exclusive Witcher Gear

Don’t miss this opportunity to acquire some rare Witcher Gear only available during this one interaction in Hearts of Stone. Purchase the diagrams for the Viper School gear from the Countess when the “Merchant” icon appears during the conversation.

If you’re interested in learning more about the widow’s torrid affair with one of your own, you can offer to help find her earring on the balcony.

The Card Shark Edit

This interaction is fairly straightforward, though you’ll want to have a solid Gwent deck assembled if you want to stand a chance at defeating this opponent. He may use a Monster deck, and is effective at utilizing it's muster ability for his Close Combat units, or may select a different deck depending on what you gave as your preferred faction. Decide whether or not to give Vimme a fraction of your winnings before you play (he won’t take any offense if you don’t), then lay your cards on the table. Good luck!

Auction Edit

After meeting with Vimme’s acquaintances, the auction will begin. There are three items up for auction:


Not very likeable men - Horst Borsodi

  • Starry Night Over Novigrad, by the artist Van Rough - 20 crowns (60 crowns if you have to outbid Vivaldi)
  • A rare statuette of an eagle, potentially containing rare Witcher gear.
  • A pair of spectacles that once belonged to the hired assassin known as The Professor

Once bidding on these items has ended, the auctioneer will announce an intermission and Vivaldi will attempt to introduce you to the establishment’s proprietor, Horst Borsodi. Be as charming or as indignant as you like, sadly there’s no version of this conversation that doesn’t end with Geralt being “escorted” out by the guards.

Once outside, defeat the two would-be tough guys to trigger a cutscene introducing The Stranger, whom instructs Geralt to meet him at the Herbalist’s hut outside of town.

Journal Entry Edit

Olgierd's wishes were unusual, to say the least. One demand was for Geralt to bring him the house of Maximillian Borsodi. He didn't supplement this request with such key details as where this house was located or just how the witcher was to transport said real estate. Geralt only knew his first stop should be Oxenfurt, the city to which the Borsodi's had moved their world-famous auction house...
Horst Borsodi did not demonstrate a flare for hospitality. He greeted Geralt with unmasked disdain, then, upon hearing the witcher had come for Maximilian Borsodi's House, had him summarily tossed into the gutter. Geralt was still picking himself up when he discovered a stranger awaiting him there... a man who could help him fulfill Olgierd's wish.
The mysterious stranger revealed that he was planning to rob the Borsodis' Auction House. He swore Geralt would find Maximilian's House within it, as impossible as that sounded. First, however, the witcher would have to help him put together a full break-in crew of daring professionals and find a way to weaken the Redanian garrison. Though Geralt usually tried to live within the bounds of the law, this time he had no choice but to agree to help in this criminal enterprise.
Not everything went according to plan... to say the least. Geralt successfully broke into the vault, though at the cost of some nerve-wracking moments and a good deal of bloodshed. Once in the bowels of the auction house, he found out that his partner-in-crime was none other than Horst Borsodi's long-missing brother, Ewald. Cheated by his brother out of his inheritance, Ewald had planned his revenge during his long years of exile.
Geralt stands with Ewald:
Ewald had planned his revenge during long years of exile - and the witcher helped him bring this plan to fruition.
Geralt stands with Horst:
Yet now, on the cusp of his plan's completion, the White Wolf stood in his way. Geralt hadn't trusted Ewald from the very start and decided to hold his nose and support the disagreeable Horst rather than help Ewald commit fratricide.
Geralt stands with Ewald or Horst, but also demands the papers:
Yet when Geralt realized the remaining Borsodi brother was using him as well, he made sure he joined his recently murdered sibling in the afterlife. With no one left to lay a competing claim on it, Geralt took the golden casket known as Maximilian Borsodi's House and the will hidden inside it. Now he was set to fulfill Olgierd's request.
Geralt stands with Ewald, but does not take the papers:
Ewald killed his older brother, avenging years of poverty and humiliation in one furious moment.
Geralt stands with Horst, but does not take the papers:
Yet fratricide occured nonetheless -- for Horst killed his younger brother.
Geralt stands with Ewald or Horst, but does not take the papers:
The blood still on his hands, he gave Geralt the golden casket known as Maximillian Borsodi's House in compensation for his help, though not before taking for himself the will hidden inside it. With this is his possession, Geralt was set to fulfill Olgierd's request.
