We have a new building in town called The Ancient Portal World. Here you can summon unique dragons that produce a new material called platinum. There are 6 mines in the island that will produce Ruby, Sapphire, Topaz, Emerald, Onyx and Diamond.
There are also 6 mini islands on the map. The first dragon you will be able to summon is the Guardangel dragon. Like the other dragons he will produce 10 platinum per hour at level 1.
The second dragon will be the Gorgoneia dragon and you will be able to place it in to the Magic habitat. Getting Gorgoneia will give you +9 Platinum per hour. Gorgoneia Since their costs are close to the same, definitely get Gorgoneia first! It will pay off fast!
Here is the first video i made about this world:
