Here's how to find the Venomous Viper armor and sword gear during the "Open Sesame" quest of The Witcher 3 DLC Hearts Of Stone. The Witcher franchise began with a series of novels by Andrzej Sapkowski, which follow the adventures of monster hunter Geralt of Rivia. The books were adapted into a Polish movie and TV series called The Hexer in the early 2000s, but fans of the series and even Sapkowski himself hated these live-action versions.
The franchise broke out in a major way thanks to 2007 video game The Witcher. The game has players guiding an amnesiac Geralt during a quest for the King and proved to be a perfect introduction to the story for newcomers. The Witcher 2: Assassins Of Kings was a big improvement on the original's gameplay, however, and was able to flesh out the world and characters in more detail. The Witcher 3: Wild Hunt from 2015 is considered the crowning achievement of the series, however, combining everything that worked in the first two games whilst providing an addictive experience.
The popularity of the series and Geralt himself is only set to continue, with Henry Cavil (Mission: Impossible - Fallout) taking on the role for Netflix's upcoming Witcher series. The Witcher 3 also received two expansion packs, titled Hearts Of Stone and Blood And Wine. Hearts Of Stone found Geralt escaping execution by helping a mysterious man collect a debt from a cursed nobleman. It's a fun adventure and any excuse to spend more time in The Witcher's world is a good thing. The Witcher 3: Hearts Of Stone comes with lots of new weapon and armor to find, with the Venomous Viper gear set being some of the best. Most of the diagrams needed to obtain this gear can be found during the "Open Sesame" quest, but they can be easy to miss entirely.
To obtain the Viper armor, Geralt needs to go to the auction house and find Countess Mignole. Speak with her until the option to buy the four Viper diagrams - including boots, gauntlets, trousers, and armor - presents itself. Speaking with Mignole is entirely optional so a lot of players can miss it the first time. Among the benefits of this Witcher armor is resistance to piercing damage and a whopping 50% resistance to poisoning.
For the Viper Venomous Steel Sword diagram, play through the rest of "Open Sesame" until Geralt comes to the vault at the end, where players can loot to their heart's content. There's also a chest next to an alter that continues the sword diagram. Geralt will need to be at Level 39 to actually wield this sword, but among its benefits is a 75% chance of critical hit damage and a 15% chance of inflicting poison damage.
Picking up these pieces during the "Open Sesame" quest will make Geralt quest a little smoother during The Witcher 3: Hearts Of Stone. Plus the Viper gear set itself is just quite stylish.
