While mastercrafted witcher gear was the best available armor in the game for over a year, the Blood & Wine expansion gives you the ability to upgrade your sets to Grandmaster (level 40). The Wolf set is great for an all-around build and is arguably the best looking armor in the game. The Grandmaster Wolf set provides two bonuses:
- Allowing you to use up to 3 weapon oils at the same time
- Throwing bombs without delay
Start by talking to the Grandmaster Smith in southern Beauclair to get the Scavenger Hunt: Grandmaster Wolven Gear quest.
Next, travel to the archaeological campsite highlighted by the quest. Loot and read the journal to get your next destination.
To enter the room behind the portal you’ll need to loot the Purple Ruby from a nearby corpse; go back and use it to open the way.
After fighting the monsters, look for the weak wall to break with Aard.
You’ll then find another weak wall that leads into a chamber that contains all 6 diagrams of the Grandmaster wolf set; 3 on the left side, and 3 on the right.
You can now travel back to the smith to craft the set; he also sells many of the required materials.
