>'and as a blacksmith,, it in no way means that you shoud not fight,, how else can you make a good sword if you do not know what a good sword shoud look like?'

When it comes to that, lets make it so his skill in the weapon affects how well he can create that kind of weapon. Ofcourse, that would mean that the smith must know all kinds of weapons, or he would be limited to being able to create just a few kinds of weapons. Perhaps make it choosable upon creation of the character.

Make the item created character-only. That way the smith has to decide who is to be able to use the item he create. Make the items rot_death aswell. And ofcourse put a timer on it, 20-30 ticks or something, perhaps even more before he can create another item. Should make bots rather ineffective.
Make the ore expensive and only available through purchase.

Well, there are ways to solve those kind of problems if you really want to. But its all up to the Imps to decide if they think its worth the work or not.
