Ghostly Pandaren Craftsman

This ghost spawns next to one of several trees just East of the Heartland in the Valley of Four Winds. You have to interact with him, and make sure that you have one slot of bag space. He will give you the rather useless Ancient Pandaren Woodcutter after a short conversation. Once someone has spoken to him, he will despawn, so only one person can get the charm at a time. Moreover, there are some rampaging virmen in the area, make sure that you clear the area surrounding the craftsman before talking to him, as he may despawn when you get attacked during interaction.

 As he is an npc, you can add him into NPCscan, his ID is: 64191.
