Dusty Coastal Griffon Egg-alternative way

Dusty Coastal Griffon Egg is one of the 5 eggs we need for the collection "Open Skies: Crystal Oasis". There are a couple ways to reach this egg. The Griffon is a hidden mount that can be unlocked by completing the "Open Skies" collections for each of the maps in the Crystal Desert. These collections are able to be unlocked only after completing the Path of Fire storyline.
