Accidentally deleted my save so I'm going to just play Blood and Wine since I haven't yet. Thing is you don't have the superior variants of potions or oils when you start just the DLC's. Anyone know where I can just buy them?
There's several herbalists in Toussaint that sell high level recipes and the white gull based ingredients (aether, hydrangeum, ect) needed to make them. From memory, there's one near the Mettina gate in Beauclair near the grandmaster craftsman.
