Where Can I Find Galleon's Graveyard Keys?

Title ^^^^^^^

 

I found one near Llevigar one time, between all the orcs XD You can find them in every place that have the level range of the dungeon (Don't know it though)

 

Mostly in areas with the same level. So Dernel Jungle or around the Jungle Village for example. Another option is to use the Seaskipper very often you get it from the captain sometimes.

 

Seaskipper.

 

In Maro peaks there is a guy who drops them rare spawn tho

 

And Dark Forest.

 

that's the key guardian.
I choose Maro Peaks too. I saw 4 while trying to find Cyztash.
