Below is a walkthrough for the Buy a Forge task in Rune Factory 5.
Client: Darroch
Objective: Purchase a forge from Studio Palmo
Reward(s): Weapon Bread x1
After accepting this task from the Task Board, Darroch will task you with buying a forge from Palmo. In order to do this, you’ll first need to obtain a Forging License before Palmo will sell you one. You can check out our guide here on how to do that. After obtaining the license, you can then purchase the forge from Studio Palmo for 3000G, 25 Material Stone and 30 Lumber. Please note that if you have already bought a forge, this objective will complete automatically. Once you have the forge, return to the Task Board to complete the request.
