A 2nd outpost is on the horizon for Dragons of Atlantis players! Sometime in the next few days, Dragons of Atlantis will release to players the ability to start a second outpost and raise a Stone Dragon. From the sound of their latest Facebook post/tease, the Stone Dragon will be a dragon with high defense.
My guess is that you will have to get a Stone Dragon Egg by farming level 7 or higher mountains, much like the Water Dragon Egg was farmed from level 7 or higher lakes. For now, I am continuing to build my outpost and city as well as train new troops to get ready to farm mountains and create my second outpost.
