How to make an Arcanite Buoy:
Mix up some Arcanite with some Buoy. Good luck!
You didn't think it would be this easy, did you? I still owe you for the chipped scale, old friend.
P.S. I hope you can figure out a way to actually make an arcanite buoy because I just made that nonsense up on the spot. I have no idea how they're going to find Maws.
