I've gone through the Carpentry recipe list and added levels according to Lodestone as best I can, but there are bound to be errors since the Lodestone doesn't seem to be very reliable when it comes to accuracy. If you can give me an idea for the rank of an item, please either post here or on the item/recipe page.
A lot of items are things we have no rank idea for at all. I know Maple Lumber and Plank are probably low, around 2-3 or so, but would like to hear input on that. Also, does anyone have a ranking order for wood?
