1: Bringing your skill from 0 to 30 spends something around 1500 ingots, so it's best to train your skill on an NPC for 300gp. Approach an NPC and type vendor train. He will list the skills he can train. If the blacksmith skill is in the list, type: vendor train blacksmith. The NPC will tell you the price, which is usually 300gp. Drag the coins over the NPC and your skill will increase.
