Info List
The skill levels will be:
Novice (1/10)
Learned (1/25)
Master (1/50)
Grand Master (1/100)
God of the Craft (1/*)
The numbers in brackets are levels, meaning: Novice (5/10) is a novice level 5. Each level has a percentage attached to it, getting to 100% means level up of course. Novice (10/10) that reaches 100% goes to "Learned (1/25) [0%]"
Note that this will not be seen often, and neither will the system. All of the crafting ranks are actually mostly never used. I only added this so you guys can get an idea of what kind of ranking there is, and give an idea of the value of the rank he will be at shortly after the story starts.
