Hello, I have read that there might be problems when you find the diagrams of Witcher Gear before having the quest (when you get the quest later you might not be able to complete it). Thus it would be nice to get the quests easily.
And furthermore it can be frustrating when you only find the diagrams after you already outleveled the respective gear.

So if you know for sure where exactly to buy a specific map, please write it here and I will edit it here into the first post.
