Below is a walkthrough for the Buy a Cooking Table task in Rune Factory 5.
Client: Elsje
Objective: Purchase a cooking table
Reward(s): Cooking Bread x1
After accepting this task from the Task Board, Elsje will ask you to get a cooking table. You should already have a free cooking table that Palmo gave during the first time you went to his shop. If that’s the case, then you’ll automatically fulfill the objective of buying one. If you have broken your cooking table, you can purchase another from Studio Palmo for 500G, 30 Material Stone and 10 Lumber. Once you’ve completed the objective, return to the Task Board to complete the task.
