i think crafting could be a bit (A LOT) easyer if there would be a crafting master or crafting book that u buy/pay to and he would tell u the recipe and better item crafting=more money to pay.
trick: how to get lots of money + extra weight simply do this: mix 3 hide with 3 shells to make a beetle shield sell each one for 60 and save 12 weight if u sell it if not u save only 7 weight
