The Witcher 3: Wild Hunt - Complete Edition

THIS IS A BLOOD AND WINE DLC ACHIEVEMENT

Really recommend making a save before crafting any Grandmaster gear as it is expensive. If you're willing to craft and use the armor, refer to the last section of the guide. You can complete another achievement in pursuit of this one, which requires you to find all Grandmaster diagrams (Turned Every Stone achievement).

For those only after the achievement: Go to Lafargue (Grandmaster Smith) located in Beauclair, South of The Grand'palace signpost in the map of The Duchy of Toussaint. Follow these instructions:
1. MAKE A SAVE BEFORE TALKING TO THE SMITH
2. Have at least 50K of the game currency
3. Craft one set of school gear (All armor and weapons should be of the same school)
4. You will have to craft the standard version and then the mastercrafted one to craft the Grandmaster gear
5. You will not have all resources available when crafting, whatever is missing can be bought from the vendor (If he has it), while others can be crafted when talking to him
6. Wear the entire set (Steel sword, Silver sword, Chest armor, Gloves, Trousers, and Boots) and wait for the achievement to unlock
7. When the achievement unlocks, you can safely load the previous save and restore your entire money and resources (You will lose the armor of course)


For those willing to craft the armor and use it, you can follow the previous steps, and here are bonuses for each school gear (Copied from BiggDope solution for Non-GoTY edition):
