First things first - where is the blacksmith in Minecraft Dungeons?

Players will find blacksmiths in redstone mines.

Since Creeping Winter update, blacksmiths no longer unlock by completing Creeper Woods.

Start the Redstone Mines mission and work throughout the level.

As you approach the end of the level, you'll find the blacksmith in a cage to the right of the exit. Interact with cages to release them and unlock new merchants.

After this, he will appear in the main world camp.
