You know the special crafting tables that let you craft special sets?
I think it would be cool to be able to learn those traits.
You could spend a passive point on each table for each special trait.
Example. You find the Death's Wind station. Instead of having to keep coming back to this area, you could spend a point in a passive for metal and could craft metal items of this set anywhere. Spend points in wood and cloth and you could craft all three stations of that set from anywhere.
I don't think this would be unbalancing in anyway. Gives us a reason to spend more points into crafting, so players could be more specialized.
Any thoughts?
