How do I get a Stone Dragon Egg?
Stone Dragon Eggs can be found at Level 7 Hills and higher or in the Shop.
Important: You can only get a Stone Dragon Egg at a Hill by sending attacks with a Great Dragon or Water Dragon. Your Great Dragon or Water Dragon must be present on a march to acquire a Stone Dragon Egg. However, drop rates for the Stone Dragon Egg have been increased to account for this requirement.
Players have the lowest probability of finding a Stone Dragon Egg at Level 7 Hills and the highest probability at Level 10 Hills.
Stone Dragon Eggs can appear in Level 7-10 Hills that you have already attacked.
