That is an idea but the way i play I never look too much into those details. I play quite chaotic. I never really look at how much damage I do. I only look at if I kill an enemy easier with a bow or a sword. yes so I look at the min/max damage stats etc. But ...
I also use the stores buying price. Is the price of an item related to its strength? That is, is there a formula to calculate what a store pays for an item?
