You can buy the Dragon Eggs from Starter Pack or directly buy the Dragon on the MarketPlace.
Players can essentially buy eggs from the Starter Pack and then incubate them to hatch into fully functional Dragon. The price is 15,000 DGE for an egg in the Starter Pack. This is a good price for players to have a chance to unlock a much more valuable creature.
Otherwise, players can buy a Dragon directly from the MarketPlace. Players can choose desired Dragon at a listed price. Once purchased from MarketPlace, Dragon creatures can fully perform in-game functions.
