In this video, you can learn where to find Pearl Oysters, Penshells, and Abalone in the Castaway Strait in ArcheAge. Penshells and Abalone process into the highly valuable Sparkling Shell Dust, and Pearl Oysters may yield the VERY rare Black Pearl item, which is needed for making one of the new gliders, among other things. ArcheAge is the property of Trion Worlds and XLGames..
