If say a Paladin needs a sword, does a quest or npc give you one? Do you have to buy one? Or do you have to become a miner first to get the ore and then a blacksmith to craft it, in order to continue your Paladin adventure?
Or is it so that you can just make better weapons for fighter classes, meaning defeating monsters will become easier, when you also are a miner and blacksmith?
And on a different note:
What's the function of that tiny sun-like icon in the upper part of your lower screen? (where the map is)
