The Blacksmith (鍛冶 Kaji) is a combat physical class introduced in Fire Emblem: Fates. One of the possible promotions of the Oni Savage class, Blacksmiths wield Clubs and Katana as their weapons of choice and are treated as a Hoshidan class. In stark contrast to Oni Savages, Blacksmiths have high skill stats and decent speed, but essentially have to give up on improving upon whatever magic they might have obtained before promotion. Statistically they are much closer to heroes, but prefer axes to swords and exchange a bit of skill and speed for a bit of additional defense.
Thanks to their Salvage Blow skill,they are an excellent source of income during skirmishes , should the player choose to engage in them. It is typically not reliable enough,however, to make a big difference during the main campaign,especially if the Blacksmith is a low-luck unit such as Kumagera. Their access to lancebreaker , coupled with their reasonable speed and defense,makes them a good answer to lance wielding units, but this only comes into play at very high levels.
