To access the blacksmithing station, simply head toward the Crafting teleport in the main city temple, as shown in the image. After going through the teleport, simply go to the right, and you will be at the blacksmithing station.
Interacting with the alchemy station will open a window that contains all the possible recipes available to craft, along with the required materials for each recipe. Each recipe requires a certain amount of BlackTalon Coins, the main currency of the server, as well as Gold.
In addition to material costs, the recipes will also require a certain amount of crafting skill to complete. This means that as you craft anything within Blacksmithing, you will gain experience for the Blacksmithing skill. You can see your current crafting skill progression on the character information panel, as shown in the image.
