Blacksmiths are a crafting class, you don't fight with it. Throughout the beginning quests you'll end up being each of the crafters at one time or another.
Your world is just the server so it doesn't really matter unless theres people you want to play with.
Didn't really need your own thread for this *KAMEHAMEHA*
I know Im sorry but I wanted a fast awnser so I could start playing but I had to pick the class my self anyway >< picked blacksmith so I will do no battle at all ?
You don't need another character to level blacksmith, just change your class to blacksmith, or other crafting classes,or even other combat classes, 1 character can do all of it
