The Quartermaster at the Nilfgaardian Garrison crafts the Viper Silver Sword for me, which will come in handy when I fight the Griffin in White Orchard. I also add Runestones to my weapons and an Igni Glyph to a pair of boots while I’m there. All in preparation for the Griffin fight to come. I could also craft some new armour, but I don’t bother. What I’ve got is fine.
