A Dangerous Game in The Witcher 3: All 3 Gwent Cards, Duke and the Best Choice
Witcher 3 A Dangerous Game walkthrough: where to find the Isengrim, Natalis and Fringilla Vigo cards, whether to kill Duke, money or cards, and the missable jade figurine.
In this article (0 sections)
Updated October 2026. A Dangerous Game is a Novigrad side quest in The Witcher 3 where Zoltan asks Geralt to track down three rare Gwent cards before a gangster called Duke gets them. It ends with a choice: take the money or keep the cards. It is missable, so do it before you leave for the Isle of Mists.
Quick answer
Starts: outside Rosemary and Thyme in Novigrad, after you rescue Dandelion (A Poet Under Pressure). Suggested level 12.
The 3 cards: Isengrim Faoiltiarna (Zed's house), John Natalis (Ravik at The Golden Sturgeon) and Fringilla Vigo (Caesar Bilzen's secret collection).
Best choice: keep the cards if you play Gwent; take the gold (150 crowns) if you don't. Either way you can still get the cards later from the prison warden in The Great Escape.
Duke: killing him or leaving him alone changes nothing.
| Detail | Info |
|---|---|
| Quest type | Secondary quest |
| Region | Novigrad |
| Suggested level | 12 |
| Starts after | A Poet Under Pressure |
| Reward | 150 crowns or the Isengrim, Natalis and Fringilla Vigo cards |
| Fails if | You travel to the Isle of Mists first, or already asked Zoltan for help in Brothers in Arms: Novigrad |
Missable: finish this quest before you go to the Isle of Mists. It also fails if you already asked Zoltan for help in Brothers in Arms: Novigrad.
How to Start A Dangerous Game
After you save Dandelion, go to Rosemary and Thyme. Zoltan is outside arguing with some thugs. Their boss, Duke, leaves with his friend Earl, and Zoltan explains: he has started trading Gwent cards and needs three rare ones, Fringilla Vigo, Isengrim and Natalis. He sends you to a fence called Zed.
Where to Find All 3 Gwent Cards
| Card | Who has it | Where |
|---|---|---|
| Isengrim Faoiltiarna | Duke's bandits, after they kill Zed | Zed's house on Glory Lane |
| John Natalis | Ravik (Ravvy) | Ground floor of The Golden Sturgeon |
| Fringilla Vigo | Caesar Bilzen | Hidden room upstairs in Caesar Bilzen's house |
1. Isengrim: Zed's house
Nobody answers Zed's door, so go back down the stairs, climb the ladder in front of you, then the next ladder, and jump across the gap to an open door. Inside, Zed is dead. Two of Duke's bandits are searching for his ledger. Kill them: one carries the Isengrim card and the key to the front door.
Then use Witcher Senses to find scratch marks under the stairs. Cast Aard at the boards to reveal a chest with the Ledger of Income and Outlays, and take it back to Zoltan. The ledger shows that Zed sold the other two cards to Ravik and Caesar Bilzen.
2. John Natalis: Ravik at The Golden Sturgeon
Ravik is on the bottom floor of The Golden Sturgeon, cornered by Earl and another thug. Earl offers a Gwent game for Ravik's life and the card. If you refuse or lose, Ravik dies and you fight; if you win, Ravik lives, but you still have to fight Earl. Either way you get the card, from Ravik or from his body.
3. Fringilla Vigo: Caesar Bilzen's house
Meet Zoltan outside Caesar Bilzen's house. Caesar invites you both to a long, drunken dinner about fishing. When Geralt is sent for more booze, go upstairs and use Witcher Senses:
- Turn the knife on the sideboard: a drawer opens with a triangular key.
- Put the key into the triangular hole in the bookcase: another bookcase slides away.
- Climb the hidden stairs to Caesar's collection and take the Fringilla Vigo card.
Don't miss the jade figurine. It is in one of the cupboards in the collection room, and it is the only way to start the side quest The Soldier Statuette.
On the way out, two dwarves sent by Cleaver come for Caesar. Fight them and Caesar thanks you and leaves town; walk away and they will probably kill him. It does not affect your reward.
Chasing Duke: Leave Him Alone or Kill Him?
At the meeting point the buyer is dead and Duke has the money. Zoltan holds off the thugs while you chase Duke through the towers and down into the sewers. There is no time limit. Kill the drowners, break the weak wall with Aard, and you find Duke lying wounded.
Get the money back, then choose to kill him or leave him alone. It makes no difference: he is badly hurt either way and the quest continues the same.
Tip: a second breakable wall south of where you find Duke leads to a tomb and the short quest A Tome Entombed. Do it now; the spot is hard to find later.
Best Choice: Money or Cards?
| Choice | You get | Zoltan |
|---|---|---|
| Take the gold | 150 crowns | Finds another buyer for the cards |
| Keep the cards | Isengrim, John Natalis and Fringilla Vigo cards | Pays his debts with the money |
Our pick: keep the cards if you play Gwent at all, especially if you are going for every card. If you don't care about Gwent, take the gold. Good news either way: if you took the money, the same three cards turn up later on the prison warden during the main quest The Great Escape.
