How to get the Viper Witcher Gear

In this guide, we’ll explain how to get the Viper gear that was added in Witcher 3’s Hearts of Stone expansion. This includes the locations of the Viper armor and steel sword diagrams and the silver sword.

This medium armor set is themed around poison, so it has high poison resistance and the swords have a chance to poison on attack. The armor looks like a recolored version of the gear you start the game with.

All of the five diagrams you need to craft the Viper gear set can only be found during the quest Open Sesame in the Hearts of Stone expansion. Meanwhile, the Silver Viper sword doesn’t require a diagram and you pick it up on its own if you choose to help Olgierd in the expansion’s main quest line.

Read on for a detailed walkthrough.

Viper Armor Location

The four Diagrams for the Viper armor (armor, boots, trousers, gauntlets) can only be obtained during the beginning of the Open Sesame quest, when you are inside Vivaldi’s auction house. They are sold by Countess Mignole. You won’t be able to come back so don’t miss out on buying the diagrams.


Viper Venomous Steel Sword Location

The Steel Sword diagram can be found inside Borsodi’s vault during the game Open Sesame quest, in the final room.

Viper Venomous Silver Sword Location

The Viper Silver sword can only be found if you choose the “Help Olgierd” option during the ending of the expansion. You can then find the sword directly (no diagram required) inside the shadowy realm that Gaunter O’Dimm puts you in.

From the starting area, go straight down, then across the bridge, and then go left down the path.

After following the path, you should see some stairs leading up to an area with a red glow around it; jump up the broken stairs and you will find the sword inside a rock.

Viper Gear Stats

The Viper witcher gear set provides very high poison resistance and a chance to poison enemies on attack with your swords.

It’s the only Witcher School gear set that doesn’t have any set bonuses; however, its stats are still quite nice, especially if you prefer the idea of poisoning your enemies to death.

Here is a closer look at its stats.
