Below is a walkthrough for the Craft Some Armor task in Rune Factory 5.
Client: Murakumo
Objective: Craft some armor using your crafting table
Reward(s): Aquamarine x1
After completing the Buy a Crafting Table task, you’ll be able to accept this task from the Task Board. Murakumo will show up and ask you to craft some armor. The easiest recipe to make is the Shirt which requires a single Cloths and Skins type of material. The easiest to obtain is fur which can be dropped by the Wooly and Fleecy monsters. If you have Clippers that you can buy from the General Store, you can use them on the monsters for guaranteed fur. Once you craft the armor, return to the Task Board to complete the task.
