My question is this.
In the help sction of the treating Injuries guide, it says "Lower grade medical items can be crafted into higher grades by use of the crafting screen."
How do you do this? I have yet to find the way to do so. Does it require a certain level Medical bench? a certain level for my character? or is there some book/item I need to find/buy/obtain?.
Any help on this would be greatly appreciated.
