Hole Key
Access to The Hole (Rock Door)

 Hole Key allows you to open the underwater rock going to The Hole. Eventually this requirement is removed, likely during Luclin.

You can buy this inside Paineel from Rallia Hapera for around 106pp. She is on Heretics faction. Possibly only Apprehensively is needed since this is just a merchant. I was able to buy it at Amiably. **

 ** If you don’t have the Bone Crafted Key and can’t get down into the town on your own via the elevator, then you’ll need someone to let you down.**
