Well, there's a quest where you go to a circle of energy on the right, and then he asks you to collect a few things for him. I remember, one is an Iron Tree Branch, and there are like 5 of them in the jungle on the right, and you can sell the rest, and you can also go and kill a copy of the boss to get a stone, which seems to be called adamantine, and then there's a Glow Grass in the arena, and then there's a Shield that's refined to a peak, which seems to be the case, and then you can continue to upgrade (and then there are Elven Scrolls that can be opened via Pandora's Box. There's a chance that you can hand-select a hidden item, and then you can select blacksmithing for unlimited free upgrades.)
